We BROKE Metal Detecting: Oscilloscope Decodes SMF Detectors
HTML-код
- Опубликовано: 6 окт 2022
- Welcome back to the Metal Detecting NYC channel. We broke metal detecting for real! We reference a video that uses an oscilloscope to measure frequencies emitted from the XP Deus 2. The results are not what you think! We also take a deeper dive in to the capabilities of Nexus Metal Detectors, a company that produces handmade single frequency analog metal detectors whose products penetrate depths over 18 inches deep. We discuss what is marketing and what is real and we have insight from someone who knows how to build metal detectors (Nexus founder Georgi Chaushev).

Hi, my name is Merrill Kazanjian. New York City is an amazing place to go metal detecting. We have lots of parks, colonial history and great beaches for beach detecting. I have gone to all five boroughs of New York City To Metal Detect and beyond. I also currently own 19 metal detectors. I want to have the best and I want to help you choose the best as well. Below I will showcase some of the playlists on this channel:

Hello sir .am deeply burried treasure hunter .which machine is good for me to have
Hello sir am looking for burried gold during colonization and machine with big depth.
As a former senior engineering electronic technician, I will say that the XP as demonstrated in the video was showing multi frequency emission. A standard oscilloscope is not the correct device to analyze this feature. The correct device to use is a frequency analyzer, to determine what frequencies are being emitted and when.
If you do not understand how to measure the TX output of a metal detector with any oscilloscope I seriously doubt your engineering job had anything to do with electronics.
@@georgichaushev5617 Signals on an oscilloscope can overlap and I can guarantee I have worked with sonobuoys and proximity fuses, which are much more complicated than a detector.
@@vernowen2083 But the signals on the video do not overlap and are not complicated, but quite primitive actually.
LZ Lab on the video is a manufacturer of metal detectors like my self. Do you really think he or me do not know how to measure the TX output of a metal detector?
@@georgichaushev5617 how did you have the scope connected?
@@dkanetracy Pick up coil against the detector coil. It is the simplest and most effective way to measure TX output of any metal detector. All is revealed in great detail.
Hello Merrill. I'm also Bulgarian and I'm very happy to see you and Georgi collaborating. It's great that people from different countries and cultures get along and find ways to have fun together.
I like your content overall - very informative and entertaining videos, that's why I subscribed to your channel some time ago when I discovered my passion for metal detecting.
Greetings from Bulgaria,
Todor
Sometimes I wonder if all of the complexity being added to new detectors is more marketing hype than performance gains. It's nice to see someone like Georgi bring detectors back to the basics, where more is involved in understanding what the detector is telling you via audio vs making a half assed visual identification. My first detector was a Tesoro Tejon. A few knobs, easy to use, and I was pulling lots of coins, jewelry, and relics. A much simpler time.
As I understand it, Georgi is making exactly that. Arguably, he is evolving that technology further.

Hi Merill, Here is a Beach Depth Test video
White’s Electronics TDI Pro
18" deep with a US Nickel
TDI Pro test starts at
6 minutes, 47 seconds into video
ruclips.net/video/3pNtGN6rWYk/видео.html
Product Training Videos
13 The TDI Pro
ruclips.net/video/5SjUU53s544/видео.html
The Pulsescan TDI Pro uses a rechargeable Lithium Ion Battery pack as
the power supply. It supplies a nominal voltage of 14.4 volts
and approximately 500 ma of current during use.
14.4V X 0.500 Amps = 7.2 Watts per Pulse.
My first detector was a White's Spectrum XLT and as of yet never had a any equal to it,currently have White's Surfmaster PI,Garrett's Seahunter Mark 2,Fisher CZ 20 and Equinox 800.
@@lourummel2714 Here is video of old Nexus Bonanza (was only 500 Euros) no need to ground balance anywhere. 1 Euro at 16" in the salt water beach, somewhere in Italy.
You can compare the TDI response at 16" to the entry level Nexus response at the same depth. Coils are similar size 13"DD against 12" dual Mono. So the TDI should have advantage as the TX loop is much bigger than the one on 13'DD coil.
Not going to talk about total Iron rejection advantage, much lighter weight, zero interference problems ect.

I'm glad I found your channel a few months back. I have learned a lot. Thank you for your videos.
Great vid Merrill! As detectorists/consumers we should always be wary of the latest and greatest detectors which hit the market until they have been proven in the field by 'real' detectorists and not by biased marketing people. Definitely going to look more closely at Nexus and their range.
I'm a professional measurer (land survey tech) and have all manor of measuring devices. I also went to ITT Tech for a bit and may have to pick up an O scope. It's been years (and many brain cells killed) but I think I can remember how to use one. Thanks for making videos that inspire and teach, my man. And when I find an awesome permission up here in Kingston, I'll let you know. I'm working on a few.
I checked out the frequency pattern of the equinox when I first got it with my oscilloscope. The equinox instructions explain accurately whats happening with the different programs, with different frequencies being favoured or biased in each of the programs over the rest.
Cool can you tell me the diffence between park 1 and field 1 in terms of frequencys?
@@JACOB1556 The Minelab Equinox manual tells you that I think if you read the second paragraph of each separate mode description. To understand you need to be an electronics expert. People without years of real electronics training, practice and passion will struggle. Even then some will struggle to grasp the concepts.
That explains what I was seeing with the oscilloscope. Certain frequencies were being "favored".
But yet you became an XP Ambassador... lol... all in good fun
Multi in the water makes a big difference but single frequency sometimes on the Equinox does quiet it down with EMI present
The establishment of Nexus metal detectors actually has a strange connection with Gary Blackwell who now works for XP. Apparently, Georgi used to attend the same weekend metal detecting gatherings as Gary. Where Georgi was reputedly renowned for using a homemade metal detector with plywood coils shaped in the now famous Nexus coil formation.
Gary retold a story on his website about Georgi locating a deep signal with his homemade metal detector complete with plywood coil, that he was adamant was a non-ferrous target. Everyone who swung their own metal detector over the alleged non-ferrous target, said it was ferrous according to their machine. Yet when Georgi dug down to an unbelievable depth to retrieve the target, there in the whole was a non-ferrous target in the shape of a coin. Everyone present was flabbergasted!
Alas, Gary has now removed lots of the posts he once had on his website regarding Georgi and his prototype Nexus metal detector. But if you click on this link below to Gary’s website, you’ll read how highly he rates Nexus metal detectors:
www.garysdetecting.co.uk/nexus1.htm
Try a digital spectrum analyzer, I think they replaced the o-scope in ham radio.
I did a test with small gold chain clasp with the Deus 2 on the beach. With the Beach Sens multi frequency, no sound ! With the Mono frequency mode, perfect sound !
Merrill, Your video on the output power of the Manticore just happen to coincide at the same time with something I was working on with an older detector. It makes perfect sense to me that the FCC would put a limit on the power that is radiated by any brand detector. The FCC has limits on everything as to the radiated power and the spurious emissions that a device might produce that might cause harmful interference to another device such as a pacemaker. I am an electronic tech and I own an oscilloscope and other equipment related to the communications industry and RF analysis. I also own a Whites Spectrum XLT(7 frequency machine transmitting a sinewave) and now a Nokta Macro Legend. I also performed similar tests to those that were shown in the video using the oscilloscope. The patterns shown in the video show a square wave (10:45) that is being transmitted at a constant frequency, along with square waves that appear to be pulse width modulated (9:02 & 14:41) during the multi frequency programs. One pattern showing a rest period in between the positive and negative pulses(that was in their video). One of the final patterns shows what appears to be a randomly pulse width modulated signal that would be transmitted during the Multifrequency program. These exact patterns are also transmitted by the Legend. There was one pattern though that the Legend will not produce. That is, the signal shown (9:10) to have three levels to it. But I went back and watched it several times and I then saw him change the time base or volts/div on ch2 of the scope and get another signal picture which was just another pulse width modulated square wave during a multifrequency program. At (9:18) I see what appears to be one frequency being transmitted on the positive pulses and a different frequency being transmitted on the negative pulses. I have not seen this signal on the Legend. BUT again, I do not have a clear picture of what they are doing with ch 1 of the oscilloscope or where it is connected or what is triggering the scope traces. I am no expert in the subject but I think it is generally accepted that a single frequency provides deeper detection on certain objects which the frequency itself plays a big part. To me, based on what I am seeing, the term "simultaneous multifrequency" really means sequential or random pulse width modulated. I plan to do more testing. All of this does not take into account that all coils are resonant at some frequency that can easily be found on most coils. Now days, the use of electronics inside the coils themselves make this somewhat more difficult to determine. The efficiency of ANY metal detector coil is best when the coil is used at it's resonant frequency. For my White's XLT, this was frequency 4 which was roughly 6.2khz. The transmitted signal level quickly dropped off once you got away from the resonant frequency. The multifrequency machines must be either ignoring the resonant point of the coils or using some trickery such as switching capacitors in and out of the circuit to change the resonant points. Maybe that is what the electronics in the coils themselves are doing, along with implementing a pre-amp? I intend to do more testing on the legend and some of the coils (LG24, stock and LG35). And we haven't even touched on impedance matching the coil to the detector. If you are interested in my results, please let me know as this would be the only place I would post it. *UPDATE* After extensive testing I have proven that the multi-frequencies do provide better depth with M2 being the best performer followed by M1 and M3. 15Khz also seemed to be the best all around single frequency. I will be using M2!
Great video. This needs to be seen by a lot of detectorists. Those marketing people are a sly bunch for sure.
Good detective work, I love leaning new things that may improve my abilities, thanks, and keep up the good work.
Thank you Wayne!
I have been doing this since I started detecting... I told you 4 months ago I was watching one of your videos to find out what detector to get. I had mentioned then I knew the technology. I actually carry an owon handheld dual channel oscilloscope that I test when running detectors in field environments. The ultimate idea is to recreate a detector design with a scaled down version of the owon oscilloscope as the control box. There are interesting things that can be done once you have started playing with the sound wave generator incorporated into the mix
That sounds very interesting
I think the analogy about cars is spot on. Any product that tries to check multiple boxes is going to compromise on some aspects; however, I think this is the point that is missed here. Being really good at one particular aspect is fine but companies like Minelab are moving towards wide adoption and that means a well rounded machine that is not necessarily the best at one particular task, but rather does an overall good job in many different scenarios. This appeals most to their target consumer, who in my opinion, want a machine that can do a lot of the thinking for them and don't want or need a very specialized unit.
As far as marketing goes, I think this is a case of oversimplifying (dumbing down) the message for a broad audience and in fact the algorithms for the SMF have a ton of R&D behind them and are pretty damn advanced to the point of becoming seamless and invisible to the average user who just wants something that works.
i git a nexus detector myself and yessssssssssss they really go deep my best find was a silver thaler at around 52 cm deepth that should be around 20 inch ;)
So Merrill, love this video and have had the same thoughts about smf but couldn't wrap my mind around my thought lol.. I really enjoyed the tarsacci mdt8000 as a detector similar story and Dimitar did a great job on this machine . A hybrid between pi and vlf price point is the same as the manticore. High quality machine and has a found me great targets. As of now I am on the legend
Wow go Georgi!!! Thanks for sharing man . Love your content
Deep detecting has its place, but for the hobbyist who is seeking treasure targets, it is far more important to have target ID than depth. Most of us do not want to dig deep holes in hard ground only to find a pull tab or rusty iron object. Furthermore, simplicity of operation is paramount. The pre-loaded algorithms used by companies like MineLabs are pretty much spot on and make detecting sooo much easier than fussing with a bunch of dials.
My first target with my Minelab Vanquish 340 in coin mode was a solid 29/30 at aprox 2-3 inches but when I dug there a huge rusty nail was the first thing that popped out. I checked the hole with my pinpointer and there was a quarter at about 2 1/2 inches. No other detector I`ve ever had could do that.
Great video. I too would like to see this. If you remember the V3I Whites machine had three frequencies on it. This machine would also display all three frequencies and also what frequency did best on the object. Check it out.
Can't beat the whites v3i. It's a true multi frequency detector. I live mine! Steep learning curve... not a beginner detector and has pro programs that can't beat. I like that I can write my own programs on it.
Love this channel. The insight, the Humor, the unbiased presentation…Again, The H.A. Goodman of Metal Detecting. 🤙🏻
Incredible stuff dude. Major respect.
Merrill, I believe that is a TR-IB which is the same type as a Nautilus IIB - back in the late 80's and early 90's I had a couple of the Nautilus Rebels that were in a waterproof case - they were the deepest detector on our South Florida beaches at the time - I had a wire come loose one day when I was up at Ft Pierce, and I shorted it out - since I had a second one and have been in electronics since I was 14 I checked the good one and ordered two sets of all the IC chips in it including the transistors - Rather than spending the time to trouble shoot it I just replaced every IC on it - I wound up with a detector that could find quarters at least 18 inch down - Keven Reilly of Reilly's Treasured gold borrowed it a couple times and verified it was the deepest detector he had ever used - just before he passed, I changed the butteries in it since he was interested in it and when I turned it on it was dead, rather than changing the headphones I did a real stupid and revered the battery connections and smoked it beyond repair since I no longer had the spare to find the IC part numbers - I think it was in the box with five different coils for it I gave to Larane before covid - there are kits on line that will show you how to build a simple one -
after looking at the Nexus videos I wish I still had it to play with - I have a box with full electronics lab in it including the scope and also a curve tracer for looking at transiters for balancing them - I think there are some people down here still building the TR-IB as custom detectors - I do not remember what name they have on them at the moment - the ones we had down here with that duel 20 inch coil would be fantastic on the beach - Note: I think the Rebels were tuned to work only here in Florida - I took it to St Croix and the Caymon's and had to use my whites PI backup because it would not tune to be stable at either location - The Nexus may also have that issue and not work up where you are or down here without being retuned -
Merrill, the oscilloscope used to perform the test was utilizing only two probes therefore it can only measure two frequencies at any one time. The third line you see would be an internally generated composite of the two measured frequencies. Not a good test to see how many frequencies are being generated and likely that wasn't the purpose of the test. It could merely test the accuracy of the stated frequencies being measured. I saw an earlier statement from another viewer that correctly referenced a frequency analizer which would be better suited for analyzing how many frequencies. If we understood Bulgarian it would be clearer what the test was intended to prove. Keep the videos coming, love the content.
Anything that that emits an electrical signal or pulse can be measured (sinusoidal wave) like your heartbeat. The wave measures the length/time of the pulse (distance above and below center line) and the speed or frequency of the pulse (how tightly packed the up and down lines are). In my opinion depth is the most important factor because I dig everything anyway. I don't use a deus but I really doubt they would "misrepresent" frequencies.
Hey Minelab I can find my car keys, ring, ecigg, wallet with any color flashlight. I'm not gonna refuse to pick them up because I dont have the correct color light shining on them. 🤣🤣🤣
Merill,you hit the nail on the head,I to believe that marketing is a big hip when it comes to metal detectors,try the mono frequency on the deus 2 you might be surprised on how much better it works compared with deus 1.i am just saying that that the upgrades that they did on that program using the deus 2 is also proving what you show us on this great video Merrill my friend you are a true artist like myself,best of luck,thank you for insight very helpful info your always Juan.
i have done almost every manner of testing on this subject....MONO versus MULTI with the D2....
i almost NEVER even hunt in MULTI....never!!!!
the depth and operating stability and target ID accuracy of the MONO is stunning.
i simply toggle between frequencies based on machine stability...and off i go.
it allows me to run the D2 balls out....zero on the iron/zero on the react/6-7 in the audio responce//zero on the silencer with the SENS up in the 95-97 area
i have been routinely finding large cents down a foot in bone ass dry august dirt!!!!
on sites i slammed with the NOX in multi and mono!!!
so the D2 kicks ass big time but works MUCH MUCH better in MONO and the 300+ silvers i will get this year in addition to all the other incredible colonial through victorian goodies i have amassed is humbling to say the least....and MOST of the aforementioned history has been saved from sites that have been hounded by myself and other detector nuts relentlessly for years!!!......NO SHIT!!!!!
There may be a place for Nexus detectors where deep targets are sought, but for most of us hobbyists, we are not interested in digging two foot deep or more holes, especially in the packed dirt of parks or fields, and even more so when the target can't be identified as treasure before one digs. SMF works and works very well. It does what we need. It finds treasure targets and does that extremely well. With further development of SMF, there will be better target identification and faster recovery, but improved technology comes with time. Personally, I would not waste money on a Nexus.
Congrats on the 20k subs.
Thank you so much 😀
I'm an Electronics Engineer and I can state Georgi is a Genius!
Hi I'm Bulgarian and I love metal detecting I watch your videos and understand all what Georgi and others said, it's very interesting.
Thank you and welcome to my channel! 😀
It would seem inherently logical that the real dilemma concerning multifrenquency detectors is not the number of signals it emits to a target, but, how fast and accurately it can process all of this data and provide that information to the end user. A machine which produces fifty different frenquencies is useless unless it can precisely interpret this enormous amount of information instantaneously. In that regard, an oscilloscope would only provide the least important data regarding multifrenquency technology. The only real tests that would matter to an average layman detectorist is the old school method of placing a vast array of targets at various multitudes of soil conditions, depths and ferrous/non ferrous metals combined together in a small area. That would be the ultimate "proof is in the pudding" real world testing that all of us would be very interested in seeing
I have a Nexus Standard MP 2 and it is the deepest and most accurate detector I have ever tried. The coil cable has been damaged and it’s away for repair at the moment.
It is straight forward to use, you just have to take your time ground balancing.
Nexus is one of the best kept secrets in metal detecting.
I completely agree, a lot question the performance, some accuse me of making fake videos when I demonstrate Nexus ability to unmask and hit on deep targets, people have to understand that, it doesn't matter how long they've been metal detecting, when you use any Nexus machine you have to throw all your preconceived ideas out the window, they're not like any other detector out there and I wholeheartedly believe that they will remain unrivalled, people need to forget thinking the 'latest tech' must be the best, it isn't, it has simply made detecting more accessible to the masses which is great for the mainstream companies but not so good for the hobby, with all the group digs going on in the UK eventually they'll be no land left to hunt. One of the elements of the Nexus machines that I find fantastic is its ability to discriminate at extreme depth, when setup correctly the detector is never wrong, I don't dig any iron unless I've decided I want to dig it. People also seem to think Nexus is 'just about depth', it isn't, with the silver scout coils and the new 10' inch 18KHZ DD coil you have a machine that has the ability to hunt in really heavy iron contaminated ground. I use my MP V3 with the 9' inch silver scout coil to hunt on the River Thames in London and it does a fantastic job
Do you know how this compares to something like a Garratt ATX pulse induction type detector?
@@dalevanderzee4086 I have no experience with the ATX machine
@@dalevanderzee4086 I own Garrett ATX. It is way behind on the depth scale.
@@georgichaushev5617 Really, wow at the time I purchased it maybe 4 or 5 years ago, I was on the fence about Minelab or Garrett and saw some comparison videos on youtube on the depth and size of gold that the two could find and the Garrett was superior. I guess with everything, product development can improve greatly over time. I would be interested to learn more about your detectors. I will checkout your site. Thanks.
Interesting but i felt like i knew it, somewhere in the back of my mind! Its good to see and acknowledge this but then again… thats a big hole and after 2 of these im dead in the water. I think its part marketing but part comfort as well! I mean despite the “dual” freq i am not comfortable diggin deep holez. But i thank you for shedding light on this mate 👍🏼😄
Love the beers in the background. My kind of mad scientists!
Same here…I not only love going and finding stuff but I also am very curious about the inner workings as much as I can be without having access to the IP. Once someone is able to build an accurate IMAGER which reliably shows SMALL ROUND OBJECTS (coins and rings) to a depth of 15” and at a price point which is sub 2K….it’s over. Til then even the solo engineer/builder is still in the game, and is still a very viable player. Those of us who always ask HOW and WHY are true students of the hobby.
Imager will not put out of business any detector that can hit targets at 3meters plus depth, unless the alleged imager is as deep. But that's something for the future generations. I doubt any of us will live to see that day.
Big fan here. I would just like to add that I also built a hand made detector using only a one dollar mp3 device I just reverse engineered it. I was able to detect a nail almost 3 meters in opened space without emi but was unable to detect gold. Iron, Copper aluminum was highly detectable but couldn't detect gold unless it was less than an inch from the coil, I came up with conclusion that I was applying the wrong winding and wirse and the wrong frequency. After seeing this video I would like to use the XP deus
I am happy and proud that you know of existing of Bulgaria 🇧🇬. Welcome and visit Bulgaria for metaldetecting. There you can find a lot of old coins really old
Very nicely done again brother! I do need help with a waterproof cordless headphone for the Nokta Makro pulsedive. Does this even exist?!
Short answer: It all depends on what you are going to show the audience. It's not just about the oscilloscope or the spectrum analyzer, but also about how the signals are generated and how the experimental setup is arranged. Basically, you can sell anything to the audience if you do it smartly. If someone is honest, they will publish all the details and circuits from the measurement setup as well as the names of the devices used, so that even an experienced person can reproduce the measurements. Kind regards and thanks for your videos.😉😁
Yes thanks for the video definitely multi has a place in metal detectors particularly wet salty beaches environments so to has single frequency in certain situations They are all different tools to help us achieve the best possible outcome .👍
This is one of your best videos!
Thank you!
Very interesting but going back to 8 dials to set when i can just turn on my nox and legend and start detecting would be a downfall for me. It would be like going back to my bounty hunter. Might start hunting in single frequencies just to give it a try.
Just subscribed man.Nice vids.Keep safe,God bless.Watching from the Philippines.
Thank you
@@MetalDetectingNYC You're welcome. Keep safe, God bless!
Hi Merrill this will be my last video on your thread, this is demonstrating the MP V3 with the 9' inch silver scout coil hitting a US quarter completely covered in iron. The video was shot in London in the street I live in right next to the overland railway, it's a high EMI environment, again, there's no EMI interference. I usually wouldn't waste my time with these videos, unfortunately due to the rather nasty and ill-informed comments about Nexus by some on this thread it's only fair to demonstrate that they have no idea what they're talking about, I've explained to you, it doesn't matter how much you think you know 'me included' or how long you've been detecting, you have to throw all preconceived ideas out the window when you pick up one of these machines. One last point, my machine isn't setup in a certain way to "PASS THE TEST", it's setup exactly the same as when I take it out in the field and hunt with it. ruclips.net/video/A5RdsvxcS5c/видео.html
Post them anytime Paul! It’s not a problem at all. I will check it out when I get a second!
Have you any vids on it finding anything. I am interested in seeing your vid. Regards, Mario 🇦🇺
@@MrKeenaz Yes I have plenty on my channel
Neat. I dont know why anyone would doubt your detector. Metal iron magnetic and plenty more, silver diamagnetic and gold also and plenty more. They go in completely opposite directions(Iron VS Silver) and hence should be super simple one or another to be excluded from a signal, i keep wondering if majority of detectors keep failing to do so and why the hell is that since its most simpliest two different signal changes that you can receive honestly (its like detecting if something is + or - its very simple concluding which one it is in the software and/or hardware tho, its lot of work but a simple concept and a simple signal changes). Did you focus your work more toward the software side of things or the hardware or split? :)
G’day. I’ll be honest to say all I do is turn the unit on and hope that the signal I’m getting is of the right colour at the end of the day. Thank you for your input. It’s interesting. Regards, Mario.
Excellent video. I learned a lot.
I’ve always been told that any frequency can find any target provided the proper conditions are met. That is to say, if the mineralization is right, moisture is right, EMI etc. then any signal will work. What I personally think is that it’s not a question of multi frequency emission but rather the emission of specific frequencies with parameters modified to produce optimum conditions for those specific frequencies. It’s why the Deus II has a range of preset programs that introduce additional algorithms to correct environmental conditions (like BC reject) to improve signal integrity across a spectrum. The CTX 3030 was the first to try this, the difference being it added brute force in the form of raw power to the transmissions. JMHO.
"I’ve always been told that any frequency can find any target provided the proper conditions are met."
- Very much so. This Multi Frequency technology can assist only target ID, not the depth or the range of targets been found.
Another great video Merrill as always. Being 69 the older I get seems the less I know. I will tell you this… when I fished, lures caught more people than they caught fish. Not to disparage any company or machine, i believe the aforementioned statement holds true. Georgi seems to have it correct.
Ok, I have not done this with a Deus 2 but I have with an ORX which is similar in many ways - not in that it is a multi-frequency but in the architecture. So, the control unit is not handling unprocessed data from the coil. There is digital comms going from the coil to the control unit and vice versa. What he is looking at here is the comms going between the two units. Does that mean that the number of channels in the comms channel is the same as the number of frequencies? No, they are likely only related in that more data needs more channels - which it might well do with some configurations because it is using more channels. The reason that XP coils are so expensive and there are no aftermarket coils is that the coils have a lot of the processing built in to them. The control unit is interpreting the data stream from the, displaying the results, producing the sound and sending configuration information to the coil but the coil is sending pre-processed data. The reason that I say that XP detectors work that way is as follows: 1. The coil and the controller are paired via a serial number - and the coil sends other digital information such as the battery level. That has to be a digital channel. 2. If you look at the control board for a Deus or an ORX (and I am assuming the Deus 2), there is a microcontroller chip with built in storage and very little analog electronics. There is certainly not enough logic on that board to do fast analog to digital conversion. It has to be processing pre-processed data from the coil. I think that Gregori knows a hell of a lot about analog electronics but it looks like all the analog stuff with the exception of sound generation is happening in the coil, not in the control unit. Incidentally, if you compare an ORX and a DEUS 1 controller board, they are almost the same. There is an extra crystal on one board. Most of the differences seem to be in the firmware on the microcontroller.
Could I be wrong? Maybe but I don't see how. I am happy to be corrected.
Hmmm. Many types of technology. fbs (2) vlf, pulse induction , multi iq . All for different purpose, I believe. It doesn't mean that older technology is bad..... I just love the fbs 2 on the ctx 3030. 28 multi frequencies.....
I am so bummed I missed this video a year ago ! I actually make and design anti metal detectors lol they are in the field of nondestructive testing called Magnetic Flux Leakage (MFL) Georgi is right about the more frequencies you use the less power is available to induce a voltage in your target ! I see multiple frequencies here ! Some are +Vcc to GND some are - Vcc to GND, some are +Vcc to -Vcc ! I see at least 3 ! However the coil acts like a sponge absorbing energy converting it into a magnetic field stimulating current flow in the conductive target as the field collapses the target field then collapses and sends back a magnetic field that induces a voltage in the detector coil ! This is amplified and filtered for display ! A frequency analyzer would not be helpful here since they look at RF frequency signals that work from +Vcc To -Vcc ! Just saying 😉
PS love the content 👍
Great Video man!
Hell of a video. An eye opener, thanks a lot
Thank you!

(MFD)A method of detection of metal for use in environments of varying magnetic permeability, the method includes steps of:
transmitting an alternating magnetic field associated with a reactive transmit voltage from a transmit coil;
generating a transmit voltage signal with transmit electronics and applying the signal to the transmit coil, wherein the transmit electronics comprises a linear amplifier and switching voltage electronics, switching voltage electronics being adapted such that transmit voltage signal includes switched voltage components including periods of at least two different switched voltages, a first switched voltage during a first period, and second switching voltage during a second period, the linear amplifier being adapted such that transmit voltage signal includes a component which changes approximately linearly in time during the third period which is within the said first period;
receiving with receive electronics adapted to receive a magnetic field signal;

I need to learn more about those Nexus detectors. I wonder if they have the same limitations as other single frequency VLF detectors on a wet ocean beach, where a Nox or Apex really shine.
You can push any Nexus coil right in the salt water and it will be as deep as on the dry sand. The very first test published with early nexus detectors was on the beach of Herne bay, UK.
@@georgichaushev5617 wow, I will definitely look into them.
Reminds me of the xp goldmaxx power !
I’m content with my Notka Impact as I hunt Civil War relics in South Carolina. Most items are
8-9 inches while I did find a large artillery fragment at 20 inches. My sites are mostly wooded and large coils would be a detriment. IDK how they work. 🤷🏻♂️
You swing!!!! Lol with tears!
Do you think you can take one of your old single frequency ad a large coil and tweak the settings make it perform like the nexus?
I hope that Georgi will answer this. I think he has evolved what was offered years ago.
No. It's not that simple.
Great vid,,, so what's the chances of using the Nexus in shallow
I saw Georgi respond to a few comments. Im hoping he gets to this one. I will just say that he showed me an impressive test.
Coils yes, control box no. But I'll think of something for the near future.
Hi what do you think about this detector at the beach in the black sand ?
Thanks
Thank you for this information 😎
You bet!
Now not to toot my own horn. If you go back to the first video that Merrill did about ordering the Manticore and mentioning it works on SMF I wrote a whole essay (not unusual) I mentioned my old Whites DFX that did this. And I wrote that it's just as good as today's modern machines but it has to be dialed in with too many functions, meaning it's not turn on and go friendly. BUT, and this is a big Bertha Butt, but. But I said the multi frequency is superior in target ID and nothing to do with superior depth. Then I basically said being I dig all positive signals (the DFX runs target ID in positive and negative target responses) I don't care if new metal detectors aren't as accurate if they are as good in depth but I can turn it on and go without having to adjust every damn feature to get optimal results I'm up to getting another new machine. Again being I have been getting these new machines and quit at the AT pro but I'm in a toss up between the Deus and the Makro. I have a personal mental issue with Minelabs. Then I got a reply from another old DFX user commenting the same thing.
Merrill the Beach Hunter ID (BHID) runs on 3 and 15 kHz just as the DFX. The DFX came out of Whites engineering of the BHID but added individual control features to create a superior land machine. The DFX allows you to turn of either frequency so you can hunt in 3 kHz for coins like silver or copper or you flip to the 15 kHz if your targets are lower conductivity like gold, nickels or small aluminum. Then in heavy trashy areas you can pick one of two dual frequency modes Best Data or Correlate best date give you the ID on which frequency has the best response like the 3 kHz and your target was a Merc dime or the 15 kHz and the target was a buffalo nickel. It works best for coin shooting. Coorelate takes the signal from both analyzes it and gives the probable best ID. It is most accurate in the presence of high iron trash. We're talking a 20 year old detector that was so ahead of it's time and hard to learn it put itself out of business but if you want to understand a little more see the tech videos on the DFX it will help you understand why the BHID reacted how it does. It also teaches people how detectors operate. White biggest problem was they never spent money to advertise so they let other companies sneak up on them but they were a world leader for the longest time. You love digging gold try checking into the TDI or their !attest pulse detectors that actually have some discing features but you will not get a detector that digs gold deeper then a Whites TDI. BTW I have the BHID also in a 9 1/2" (950) coil and a 12" (300). And I have an old Whites pulse inductor with the diving (weighted) coil. The PI pro or pulse inductor has dug more chains, bracelets and earring then all other detectors combines. It's a depth monster. I easily dug gold rings well over a foot constantly. The trade off you get some trash. To me I take that trade off all day and have a mini jewelry store to show for it. I'm just saying? I respect everybody for what they decide but this info is not new. It's just been a trade secret. Something to think about in the future is Whites sold all their parents, tooling and trademarks to Garrett's so in the future Garrets may be worth taking a look into they have been working on building detectors for over a half a century including the technology this guy brought up. There's also beat frequency we don't hear about but exists and worked well it just wasn't pushed like these other methods were. I grew up with a dad who built detectors so I kind of seen a lot of crazy things including a coil wrapped around plywood he mad in 30 minutes to prove a point to me when I was a young know it all.
Good video people need to see more of this and less of Minelabs false claims. That's IMO of coarse
I'm in detectors since the late 1980ies, replicated 2 from scratch, coil included and still can say it's not easy ... at all.
First you have to understand how the first detectors work, BFOs, IBs, VLFs which are sort of a branch of the IBs.
and how they generate signals, catch up the received responses, amplify and process them.
Then you have to understand the different filters and their influence on the output.
You have to understand at least how the basic components work and play together, or do not: resistors, inductors, caps, diodes, transistors, opamps...
Ad the different coil shapes, like mono, dual (TR), quad, DD, 8, and some other amazing exotics. You've to love electromagnetism and soak your brain with it.
As I said, it's not easy and it won't be.
It's a whole history behind, with it's early brands and often same engineers involved. . And as a non US, I admit that all the real legacy is US, with the PI development being mostly UK (Eric Foster).
You shall read Carl Morelands "Inside the metal detector"! There is no go around.
I followed him 2 decades ago on the good old geotech forums, he knows what he talks about. Btw, geotech was the place where the chineese got sight and grip on the US patents to copy... but never archived the same quality dedicated US engineers were able to deliver. But its the reason whg yoh have to register for geotech.
It's not simply reproducing, it's more. Those who understood this are now producing Nokta, XP, etc.
Once you understood this, then go digital and multi freq
As for the oscilloscope... i guess by these modern youtube times, there must be online tutorials.
2 of my still in use best horses are IBs from the golden 1970ies and i own around a 30, oldies and recent ones. Not to speak about those i resold.
My secondary coil are my ears, amplifier is my brain, main processor is my nose.
Edit
No pun intended with the foregoing to anyone. I'm pure analog.
LOVED your conclusion!
My beach machine is the Excal, an early Minelab multi frequency machine (BBS) But inland, in the woods, my colonial coin and relic machine is the Minelab Xterra SINGLE FREQUENCY machine ! My go to coil is a large 3KHZ. coil, nothing comes close on big colonial coins and relics.
Single frequency is highly effective on colonial sites BUT BUT requires very effective MANUAL ground balance, sometimes every few minutes. It's not for lazy people.
I almost never go near old parks BTW so can't say anything about operating there or what machines might work or not. Neither the Excal or the Xterra is a good park machine in my opinion, and my fave places are the beach and the woods anyway. back in the day the analog White's 6000 DiPro was a killer park machine, and I still have mine though I seldom swing it any more. The 6000 was single frequency, as were all the machines in that era.
There used to be a couple guys that hot rodded the old analog machines, repalcing some factory capacitors and other parts with top of the line stuff rather than ordinary common parts used in large production. Both of these guys are dead now I believe. But their machines were killer compared to production machines, close to a hand built, hand tuned unit. Sadly, I never had mine done.
I was out last weekend detecting using the Vanquish 540 with the 10inch coil. I Did not dig 20-22 vdi. This guy shows up Gets out his Deus2 went over ground I swung over yeah I missed some rings(bubble gum Machine rings) He dug a few of them that morning. Does that make the Deus2 better detector then the Vanquish? No I just did not dig those Numbers/tone. I did hit a silver dime at around 8 to 9 inches down. And we both end up with a handful of clad. ( I sometimes wonder if single Freq, is better then Multi Freq. )
hey! nice channel
why dont you have a excalibur 2 for the beach??
CCCCCooolllll ............... Je pense que le multifréquence et meilleur pour les terrain minéralisé qu'une simple fréquence, la vidéo du nexus semble être sur un terrain avec 0 minéralisation, ca va toujours bien quand il n'y a pas de minéralisation.
Pozdrav! Great channel. I see that you are so passionate about metall detecting and related devices so i took some time to reveal few secrets that i hope you will find useful. I'm working on completely new type of crazy complex detector(aiming for 3 meters depths and clarity of signals and easy of use) but to help you understand about frequencies and all around : soil/ground does not like high frequencies, the higher the frequency the less the depth(unless you comppesate it with tons of power), yet higher the frequency more stronger and faster Eddy currents(electricity) will be induced in buried metals, hence they create electromagnetic field around them from where detectors have various means of picking it up(style choice haha), and as obvious those two things are contradictory(so what now high or low frequency?). So for example ground penetrating radar works on lets pick 79MHz for example or up to 500Mhz and it creates rather actual radiation in its signal antena(much as radio station) that punches thru the ground in contrary(and it manages to do so because of the high power output that is sent into the coils so it forces thru the ground anyway despite the high frequencies) and mainly purpose of it is to measure the time from when radiation was created until it returned/reflected itself back into receiver antena hence that way mapping subterrain cavities and shapes of objects since radiation that hits different materials has different return speed and yes it also can detect what material is in question, problem with this approach while art in itself is that as soon as ground becomes more conductive it performs much worse to the point where it can not penetrate more than few centimeters(clay beach, wet, high mineral ground) as also the specific radiation approach is supceptable to rays of radiation bouncing in wrong angles when it hit subterrain rocks. < what i admire about ground penetrating radars is that they can scan in 3D the object they are hitting(imagine seeing the exact shape of the coin you are scanning?) so i love that fact and will include this feature also in my machine by the way(comming from a 10 years of video-game industry can make it even fancy). Now regular detectors have very low output power(why?) , i guess keeping the price down since components and overall design of everything if works with less power needs cheaper and more common electrical components and when you add higher frequencies smd components it can contribute to the machine build costs, and then there is a weight factor of the whole device and so forth = result is that they are not powerful as they could be(depth) and not precise as they could be(cheap ass microcontrollers - so they can offer low prices to you all) by having limited processing power hence their processing of the signals received is limited by that microcontroller or microprocessor power. So if device keep being confused its because partially of that processing limit(either they was cheap-ing out on it, either their processing code is not fancy enough, either they do not care, or any combination in-between), thats the software side of things, for the hardware since devices detecting tech differs its hard saying but the fact is that coils play a huge role, and they do (number of turns, shape, dimensions/how big, how many and how they all collaborate together < which from detector to detector can be completely different) but what is the same for all of them and what i am noticing is that it seems not a single detector company our there understands how to make a good freeking electro magnet in a first place and then comes overall understanding of the electro-magnetic fields, what i want to say is that all of even existing detectors can be easy improved (clarity of signal, depth) with few tweaks of the coil, but when you are manufacturing something as it goes you want it to be cheap for you so you can offer cheap on the market. TAke for example famous double D coil , maybe it serves you well guys and it is easy tweaking those 2 or more coils to cancel each other so any disturbance causes easy signal for the machine to be processed, but notice i said a word "cancel", so if you want to look into the ground deep you are not supposed to freeking kill your electromagnetic fields haahhahaahha but enhance rather isnt? So there are planty of facepalm designs that may do decent here and there at specific conditions but its just hilarious all the coils im seeing out there (yes basics of electromagnetics are there, the teams who work in all those companies have that much knowledge but are basics that you can google in 10 minutes, there is so much more to it that can be done). But yet again not everyone has more than 150 bucks for a detector so things are okay i guess(i will never make them a competition with my device since mine gonna cost tears). I did speak about frequencies shortly and let me extend lil bit : so firing up slower frequency and low right after each other(as seen on the oscilloscope on the video) will cause exactly this : low frequency(goes slightly deeper and has less chance exciting materials in the ground in order for it to get a good signal < its fine for roughly trying to estimate if there is anything bellow in the ground and not being too much smart about what it is and also smaller the object the worse the signal) hence it is good for wet ground(beaches), for high mineral concentrations soils, clay, then firing the higher frequency(does not penetrate into the ground that much as low one does but in return it will have better signal from metals from the ground) hence it is just fine for shallow hunting in dry areas. So either both frequencies in the same time lets say forced into two separate coils or a 2 frequencies one behind another in a same coil does exactly what i explained regardless. Then comes the processing of returning signals from those two frequencies ranges < here you can play however you want(as far as your coding capability and creativity goes) in order to represent the user with interesting data. So what 2 or more frequencies actually mean? Its just having 2 devices in one, thats all(its like having 2 different detectors that operate on different frequencies with addition that both detectors can share the data and can agree on what they are looking at). So for dual frequencies ill give it a score of a 2 metal detectors and a half inside of one. With all of that said i laugh on all of that and my device will be 50 years ahead of all that, so wish me luck putting it together hahahahaha . I hope that this small electromagnetics speech makes you slightly better hunters guys from this day
IF they was really smart with those double frequencies i was thinking 2 minutes and realised that they could make a good inovative design by doing next : fire up low frequency so it penetrates deep(simple low frequency electro magnet that does not listen back), then what happens is that object deep underground can pickup at least some of those and send back its own electro magnetic field that is weak toward the surface= which efectivelly reduces the depth of the object in a virtual manner since its electromagnetic fields are now close to the surface which virtually/pseudo moves the coin toward the surface, then higher frequency coil that is a signal and listener in the same time will fire up right after the low frequency and now since the coin is "closer to the ground surface" this higher frequency coil will touch it / fire up and measure its own changes in phase shifts and voltage/amplitude. There, i did this in 2 minutes... It will be funny if no one remember to do this and it turns out its a 10 times better tech then what they have in double frequency technology ahahhaahha. MAybe this is exactly what they did or anything in-between i dont know. I dont care my approach is far more advanced even than this. And by the way even more help for you passionate hunters out there it is actually important from which side you are scanning one same spot (north , south, west...) simply because electromagnetic fields are behaving almost as they have "2 dimensions" so if the angle of the coin is not perfect oriented there is a high chance that your detector can just do a short "bip" that you gonna ignore most likely and both the detector and you gonna consider it as a mistake tho... which is mistake in-itself, so if you doubt one single spot has something for real rotate yourself arround that same spot and do both : the slow swipe over it and fast swipe over it, and by swipe i mean swing your detector - because depending on the material in question in the ground small chance exists that additional swipe introduces more stronger signal, because thats how Eddy currents works, faster the magnet comes near the any coil the more excited it becomes.
Oh one more thing, if you want fast recovery just shoot the opposite electricity(carefully calculated/preferably dynamic/ever changing based on the case) into the same coil(after the brain did signal about successful pick-up) on that way it gets into its own 0 state much faster. Simple as that(for the most detectors this is not welcome since they use the full signal even decaying end of it to figure out some stuff i guess). And recovers fast. This requires more software efforts and more hardware components so not many companies gonna make any big leap on this fast recovery side(and if they do they gonna ruin some other stuff, its all about balancing the usage, its unbeliveable hard making it "do perfect everything"). The other way is using the second coil depending on how winded it is and if DC pulse, just pulse with other coil so the one who is listener its magnetic fields gets cancel (opposing magnetic fields do cancel each other, in case that device brain does not need the complete cycle of the receiving signal).
There was a commercial that had the same music from “You Don’t Foo Foo on Copper” rap….. who’s that guy with the mustache? LOL Just saying Barry doesn’t like that Merrill, he may get you with a rusty crowbar.
I love your channel Merril
Me as well brother ! I don’t drink smoke etc and have no friends because of it haha ! Keep up the great work brother ! Thanks for sharing !
Definitely food for thought
I know this is reviving a long dead post but, are there any comparisons of SMF detectors being used in multi mode then compared directly after to the same one in single mode to compare in a real world test?
Nexus is an amazing detector.I used to have one Nexus Bonanza and sold it ,now can't afford to buy another. You need to check the Bulgarian detectors - Nexus,Golden Mask,Thracian, Wave Terminator, Pirat, Detech . They all are deeper then the "top" detectors.
Ok as someone fairly familiar with rf transmitting and someone that went to college for electronic engineering. An oscilloscope is a poor choice for testing multiple frequencies at once, especially if they are spread farther than a few kHz apart. The best choice here would be a spectrum analyzer. I would like to see this same test on a spectrum analyzer before any true conclusion can be made.
I appreciate the suggestion!
@@MetalDetectingNYC Now I am genuinely curious. I am going to have to dig out my analyzer out of storage and I will do a video of it with the equinox
I am not sure what college have you studied at, but from what you say you need to go back and read those books again, but for real this time.
An oscilloscope is the best possible tool to show any package of frequencies, because it is not only just showing the variables, but it does so in a graphic detail that no other tool does.
Analyzers are for "engineers" that do not know how to use an oscilloscope.
@@georgichaushev5617 I'm not denying that an oscilloscope can measure the frequency or frequencies. I'm simply stating that if someone wanted to see the full range of transmitted frequencies it would be more clearly visible on a spectrum analyzer. It would show what frequencies are being transmitted and at what strength. This would give a better picture of the transmitted frequencies and the spread of said frequencies. I'm not trying to belittle or undermind the experiment in any way. Just trying to simplify for those that may not understand an oscilloscope. No harm ment.
Hmmm...very interesting, I have a tek MDO 4104-6 and can help anyone interested in duplicating this experiment. I do not have any of these metal detecting machines, I only have a PI machine, the Garrett ATX with Deepseeker package. My MDO has a built in spectrum analyzer. We could look at the time and frequency domains of the signal simultaneously. Since I am very new to this hobby of metal detecting I do have a lot to learn on the inner workings of the machines used in this hobby. I have electronics and computer programming experience and play with microcontroller embedded programming on the ST line of microcontrollers. I am not sure how useful the frequency domain will tell you about the signal unless you are interested in the harmonics also being generated by the signal. To solve the problem with multiple frequencies my MDO has quite a large capture memory which makes sampling the signal over time much easier allowing you to drill down on specific sections of the waveform to examine its characteristics. The oscilloscope used in the video is very old crt type of scope with limited functionality. Let me know if anyone is interested in pursuing this further. Thanks to all for this interesting topic :)
Sounds like a metal detector shootout coming! As for measuring detector output and frequencies with an oscilloscope versus a frequency analyzer? That's an apples to oranges comparison. 2 different ways of measuring the same thing, both good at what they do if you know what your doing. Hard to beat a depth shootout in similar ground side by side though. Let's go with that!
Nice video I enjoyed it, catch you on the next one. 🇺🇸
Think the bigger question is what Frequency does the NEXUS use? While the Mibelab top 2 are the Manta and Nox are commonly run as Multi Frequency detectors they csn also be run as single frequency detectors, by selecting a singie frequency.....what makes the NEXUS able to penetrate to 18" ?
Does this mean that as an Example a Nox never truly runs a single frequency even if a single is selected say 4mgh? If the multi frequency in a NOX is the Park vs Beach vs Relic setting which rebalance the multi frequency output to favor certain objects?
I would like to know how he had the scope connected. I have 3 scopes and a retired EE friend of mine has a spectrum analyzer and we were going to do some test and haven’t quite figured out how to get the readings without having a direct connection to the TX which would pretty much require tearing the coil apart
A pick up coil against the detector coil.
To make another point. At 1:30 6 coins are on the floor and when the detector passes over it I hear only 4 beeps. The detector with the bigger coil has failed to pass the separation test. When the iron is placed over it, many times there are only 3 beeps this showing this detector with the big coil misses between 2/6 to 1/2 of the objects in areas with heavy iron.
If the detector gives you one tone on two coins this does not mean is missing them, but it means it is grouping the individual signals. The high tone indicates non-ferrous, not the individual beep.
The whole point is to get the coins no matter what. It is not important if the beeps are 5 or 2 or 3, but the fact that the very long Iron wire does not stop detecting them. Good separation is when Iron and non-ferrous are together and you can hear the non-ferrous, no matter what. This is what Nexus does very well.
Of course you can always go for SMF detector that will not find even one of those coins under that same Iron wire, but at least you can count some beeps.
You can make million points, but there is only one that counts.
You will not find any detector on the planet that can beat Nexus MP V3 in Iron contaminated conditions or on raw depth or/and discrimination at maximum depth.
@@georgichaushev5617 understood. The video shows off the discrimination as opposed to separation speed. I don't think it should have been juxtaposed against the manticore video. The manticore video shows a detector with great separation speed. Your videos doesn't (testing something different) and you are right, with a large coil, that type of separation shouldn't be expected. However given the setup of the manticore, the comparison was made, and the Nexus detector didn't separate as well. In NYC having a great separation speed is a must! We are completely inundated with iron.
@@georgichaushev5617 A detector that groups multiple like signals in NYC wouldn't be too helpful. We have large cans, copper pipes and tin lids everwhere. One way to decide not to dig is to listen to the size of an object.
Also when you say "Good separation is when Iron and non-ferrous are together and you can hear the non-ferrous, no matter what." That is actually discrimination. To be able to discrimate against the iron and hear the non ferrous. Separation is the ability to separate multiple targets, which is difficult with bigger coils.
@@TheDetectingZone
That was the whole point of my demo. Coins UNDER Iron, not next to, not in between, but right UNDER. Try any detector you can get your hands on and see what comes out. Then we can discuss NY parkas as if they are the only places on Earth littered with iron.
@@TheDetectingZone Before you attempt to teach others, especially someone twice your age (me in particular), you have to be able to demonstrate real expertise in design and manufacture of metal detectors. Clicking the programs of digital detectors doesn't count for a dung, because that doesn't teach you how actually metal detectors work.
Separation is the ability to separate the non-ferrous from Iron when they are together or close by. It has nothing to do with counting coins or individual targets under the coil.
After all what would be the point in separating the same types of targets if the detector can not separate the good from the bad and can not see them near or under iron.
Since you evidently know nothing about coils I would suggest you to leave the coil topic until you learn more about it.
I can demonstrate how 20" coil beats any time any detector on separation, unmasking you name it regardless of their coil size. Because those have nothing to do with coil size despite what your eyes are telling you.
There is much more to the metal detectors than meets the eye.
Correct me if I am wrong, the Oscillator scope was the wrong tool to measure SMF Khz waves?
Spectrum Analyzer is the correct tool, I gathered or not?
Also is changes from the earths natural occurring electromagnetic field and interrupted by a metal detector for milliseconds to seconds more of something to do with Nuclear Physics understanding whats going on with the ground disruption, I understand the electrical engineering side that takes the readings but is the secret sauce really Nuclear engineering understanding of the earth's magnetic field being disrupted? I'm here to learn.
if you want to get a nexus i would suggest the nexus standart mk2 which is the best they have in my opinion greetings from bavaria
Mk2 was a great detector, the pinnacle of resonant tuned designs, but it has been long surpassed by the MP series and now is an archive model no longer in production.
Never Been a fan of multi frequency detector, I like my gold kruzer I use it for most all my hunts .
😮Wow!!! Amigo
This detector is good do you think this detector will be good for the beach?
And in the black sand?
Good video
I can’t wait to test!
I was thinking that I heard that XP frequency combinations in it’s various multi frequency programs is proprietary. If so, wouldn’t you think that they would have made it a little bit harder to decipher?
Just a thought
The honest answer is that is BEYOND my metal detecting tech knowledge. I see your point. I will infer that any detector does require a pulse in the ground to function and that is something that is possible to measure.
An Oscilloscope can measure anything that comes out of the TX coil of any metal detector, regardless of "proprietary" claims.
@@georgichaushev5617 facts
@@georgichaushev5617 Totally agree, that term proprietary only means it is a way they chose to output their signal. Almost any signal can be replicated today. Microcontrollers and their embedded DACs and ADCs are so cheap and easy to use the sky is the limit. Microcontrollers are extremely powerful and with a handful of electronic components you can do amazing things. I play around with the STM32 line of MCs from ST which are fabulous and cheap.
Can't make output frequency proprietary! Oscilloscope will measure voltage/time for any metal detector output provided it is rated to measure that frequency.
Thanks 👍
How heavy is the nexus with a standard not giant coil? What’s the warranty? I’m sure smf is kinda more of a marketing technique but in my coin garden my nox and d2 smokes my buddy’s old whites machines. I think if I was in Europe the depth might be more of an appealing reason to buy. But out here I want speed and light swinging.
Even with the 9" Silver Scout coil, which is feather light, the Nexus will be heavier than Deus or NOX and similar. If light swinging is paramount for you, Nexus is not going to be the best choice.
You just need to ask Adell''s (sp?) opinion. She'll straighten this multi frequency thing all out I'm sure
Haha I’ve only been saying this forever…. The whites DFX came out in in the early 2000s …. There only filtering these machines for ease of use .
My friend Bojan is from Bulgaria and speaks..... you got it..... Bulgarian! Also, he is engineering minded!
Merrill,
8 inches to better target ID is for weekend relaxing terasure hunting good enough.
And the statement that `"if you transmit more than one frequency over a period of time will result in proportional lower power output at each of those frequencies resulting in overall lower power output" is just a statement, maybe truthful, without any evidence based on some electrical rule.
Simple result: SMF is for normal treasure hunting is simply better than single frequency. And my question is: How long is your spade? Have you ever dug "empty hole" (i.e. just mineralized soil, namely wet and without any metal object)? If I compare my ORX and Déus II, with the SMF Déus II and Programme 1 General I never did (see also XP metaldetector skill school with Gary Blackwell), instead of with ORX when I dug it just last Sunday in a very wet spring soil. The same story was years ago with XP Gold Maxx Power (and other detectors I also had - Tesoro, C-Scope etc.).
I don`t challenge the knowledge and skill of Georgi Chaushev in any case and my thumb to your video is up!
I guess it is all about what they are testing, one band or multiband (more probes), since most scopes have only dual inputs (1,2), I wonder what the multi range 40k -5 k at one blast or step by step?
Since all detectors use only one TX loop you need only one oscilloscope channel to test them.
You know a channel’s good if you are inspired to put two comments…. Keep at it Merrill, and soon 50k views and 1k+ likes will be the norm…. Keep swinging!
Honored! Im trying to grow as a detectorist and video maker.
@@MetalDetectingNYC My first target in my new yard with my Minelab Vanquish 340 in coin mode was a solid 29/30 at aprox 2-3 inches but when I dug there a huge rusty nail was the first thing that popped out. I was disappointed for sure. But I checked the hole with my cheap pinpointer and there was a quarter at about 2 1/2 inches. No other detector I`ve ever had could do that. I mean, unless it`s just a fluke? I haven`t had much time with the machine yet. Waiting on cool weather here in Louisiana so I don`t get attacked by angry yellowjackets or copperhead snakes....again.
Hey Merrill, great video. These are some of the ??'s that i'd like to ask them that build these machines. Every metal has a different electron. Gold has 79, Aluminium has 13. So why does an aluminium pull tab (the bane of us all) ring up the same as gold? Which is 66 electrons away? I've always wondered why they couldn't hone in on just the gold electrons and just build a detector just for nugget hunting. Minelab "Gold Monster" 1000 is a great detector for piking up gold but again, it'll pick up both ferrous and nonferrous metals. Even if the meter tells you iron you have to dig anyway (unless your underground on a mine wall). So even the "great gold metal detectors" are multi- frequency.. I say they should be able to make a detector that will specialize in gold and one for silver. If you want to dig everything go buy a $89.00 find it from Dollar General. Yee-Haa!!! Let freedom ring!
I might be getting out of my (growing) level of understanding but it is not just electrons that are measured. It is the mass of the object, the shape of the object plus the conductivity of the metal that affects whats called a phase shift that registers on a given target id scale.
This because the process of detecting metals have little in common of how many electrons are circulating around an atom's nucleus. Metal detectors are not capable to account for particles on atomic level. They only react to Eddy currents that occur in the metal targets as a result of the transmitted to what's them electro-magnetic field.
@@georgichaushev5617 Wow! Yet ferrous (or magnetic) and non- ferrous are on a molecular level. Magnetite is a natural ferrous mineral that a detector can pick up. Maybe i'll investigate this further. Something doesn't sound right. To me, they are picking it up on a molecular level and there's a big difference in the "Eddy" of the current from 13 to 79. If they can pin point an "Eddy" generally why couldn't they be able to selectively pin point an "Eddy". So if you can put the electro to use and eliminate the magnetic. That would seem to me to be able to not pick up any magnetics. Why include them anyway? Au, Ag, Cu, Pt....etc are not magnetic. So i think i'll work on eliminating the magnetic out of the electro- magnetic field.
@@MetalDetectingNYC Hey Merril, see my comment to Georgi above.
@@richardbeee Forces on a molecular level are not strong enough to disturb the balance of the loops in IB detector, thus nothing can be detected on a molecular level from a metal detector. If the balance between two coils is stable there is no actual detection present.
What Induction balance detectors measure is the changes of the balance in the receiving coil, not return signals from targets. That balance can not be disturbed to a sufficient level by e single molecule so that response can be registered.
Besides the sheer amplitude volume of any force in any metallic molecule is way bellow the noise threshold of the most sophisticated electronic circuit, which also means is out of chance for any metal detector to register.
There is plenty of literature on metal detectors available. You should read and study those rather than fill your head with scientific fantasies.
Use simple logic if you do not understand the science.
If detectors measure anything on a molecular level they should be able easily to detect targets the size of a single molecule, but that detector doesn't exist yet.
One of the best metal detectors ever made was the Nautilus DMC 2ba. It was a hand made single frequency USA made beast of a detector.
I have always wanted to try to operate an older detector and see if it can compete with todays ringers. I have never swung a Nexus, but I sense that he has improved on an old formula.
Very much so. I second that. Any Nautilus will batter to death any SMF detector hands down. And Nautilus is using only 14kHz concentric coils. Not even DD or any other fancy stuff.
@@MetalDetectingNYC I have a 1980's Sears and Robuck TR discriminator made by whites. You are lucky if you can find your toes in steel toe shoes with that thing! Seriously, I think it would struggle on coins over 3-4 inches deep.
@@662OutdoorAdventures There are many older detectors that can be deemed useless today, just as there many new detectors to fall in that same category.
Very interesting. I will never swing a coil that's over twelve inches. I metal detect because it's fun and a heavy coil takes the fun out. I'm 77 yo and weight does make a difference.
I agree and so does digging deep holes. cheers
The silver 11.5" coil on the video is only 450 grams.
Bro, whats the best pinpointer for saltwater beach and under water? Only interested in gold tbh, big gold small gold )
I have been using the Garrett Carrot which is NOT the ideal saltwater pinpointer. I have to eventually get in to rating pinpointers but its not in the budget right now.
@@fullhalf420 i have heard it really struggles with the small gold items
@@MetalDetectingNYC thanks. Ordered tc-110 off aliexpress for now.. will wait for the video befor plungi g big money )
