You need a shop made with mortis and tennin with pegs and wedges in the joints, and glue on wall board and ceader shingle roofing. And the power all on one wall so it can easily be shut off. For testing. A building a mri can be used in, no metal a skylight with poleblight shining in from 200 meters away. Minimum power, no metal. Itvwiuld be a perfect shop haha
That was good!! You should team up with Nuggetfinder in a partnership to make metal detector coils.
Do you actually have a video going through the coil design and manufacture? That would be very helpful.
I should but I would need to get more core material and I do not have a router anymore.
Thanks for your good information about metal detectors .i have a question about what is the ZVT technology wich used in GPZ of mainlap
That is a bipolar transmit system.
Hallo sir. Thanks for sharing all those constructing details. I would like to ask if the thin wire which connects the two carbon sides, is also connected to the negative of the battery (ground).
Yes, correct
What was your ratio of carbon and graphite? What did you add the graphite and carbon to make the solution to apply to the coil? Did you use a spray gun and how to do the four quadrant taping without making a mess of things? I read below you use a blender to get it finer. Was the blender typical one purchase at a store? The goal is 80 to 120 ohms per/sq.inch. Best I have done is about 600 ohm with many coatings shielding. This has been good info about ML coils.
I did these coils years ago, half the time i cannot recall last week.
Hi Woody
Great information, I will try your methodology. My few tries at making graphite paint has resulted with high resistance 600 to 900 ohms. Any advice on reducing the resistance would be much appreciated.
Thank you for your videos and have a good day,
Chet
The only way to get lower resistance is to reduce particle size by using a high speed blender.
@@DetectorMods Sounds like an outside job with a mask on to keep the fine particles in check.
Thank you,
Chet
Hi thanks alot alot alot.. i waiting this informatiom for along time thanks to you and to your son divd ☺️☺️☺️☺️
It's my pleasure
@@DetectorMods i made a pi metal detector ( felezjoo) it good dvise . all what you saying in video it good sulustion about shielding or the best over it i think you are the tallk about shielding perfect c....caus i askink in another placse no one anser me thanks for everything ......☺️☺️☺️☺️☺️☺️☺️☺️
Hi...about cabel of coil what made from? I mean what element get in cabel ..... thanks
Hi there! This information is pure gold!
I've been building the surf pi detector and I don't have access to 0.25mm2 tinned copper core
Is it better for the coil to go stranded tinned plated Copper 0.22mm2
or 0.25mm2 stranded copper core?
The guy who sold the pcb recomended
30 turns of 23AWG with a coil inner diamer of 15.3 to get 1.5 Ohms and 310 uH
23 turns of 23AWG with inner diameter of 25.3 to get 1.7 Ohms and 340 uH
Thank you for reading this! It will help a lot!
The Surf P.I is easy enough to get working with 0.5mm diameter 0.22 or 0.25 mm strands, 280uh to 340 uh will work.
@@DetectorMods Thank you sir!
Thanks for the info. How did you inserted the litz into the polypropylene sleeve?
I had it made for me.
very love chanell❤❤❤
In your opinion, in gpx5000, in wet sandy ground that has a little salt, with a 25 inch mono nugget finder coil, which option has the most effect on the silence of the device? Thank you, please explain what is the solution for such fields.
I would be adding variable frequency to stretch out the delay in the detector to minimise the salt response.
I watch that video 20time its very good
Just make sure not to make a resistive conduction ring or covering without an overlapping break.
@@DetectorMods i make sure no one have that informatiom about detector metal ( colecting all in one video) for that i thank you so much ..when i finesh my detector i will show how look it ...🕴️🕴️🕴️🕴️🕴️
shielding pcb of detector i mean box of detector what best shielding cover????
@@stoop-tech1060 to shield the pcb use Mu metal and soft ferrite sheet.
@@DetectorMods thanks... you know am jumping injoy and happynes thanks thanks thanks...☺️☺️ Please i have aloooooooooot question i mean in next time ...بارك الله فيك و في عائلتك 😊😊😊😊😊😊😊
good afternoon, tell me your video about gpx5000 coils. or tell me the parameters for the 26" coil. number of turns, wire thickness, resistance, inductance. thanks
Look at the newest video
❤❤❤❤ good men
Could you make me a 15 inch search coil for my Fisher CZ 6 metal detector? How much would you charge for a 15 inch diameter search coil for my Fisher CZ 6 metal detector? I want to use it for deep cache hunting and relic hunting.
I have no idea about the required specifications to make that coil, we only make pulse induction coils.
Hello, do you have a website, or email that I can contact to discuss mods for my gpx 5000, and gold monster 1000? Thank you. Great video, I'll be continuing to watch more.
Detectormods.com
When I put the coiltek 6 file on my gpx 5000, does it reach the sensitivity ratio like the Monster gold device
The Gpx is pulse induction and Gold Monster is VLF, Pulse induction is deeper penetrating but not as sensitive.
Hi Woody
Thanks for this information.
Please what is the number of turns in this coil (18 inch).
For memory it is around 18 or 19 turns depending on the type of wire and its insulation .
@@DetectorMods Thanks Woody
I bought the Litz wire from you, and I have neat and good circular tires, and I wrapped it well, and the coils were compact and regular, but for about (300uH).
The (18 inch) coil only gave me 15 turns.
And he gave me a coil (22) =13 turns.
and a 25-inch coil only gave my12 turns
I tried an inductance meter on a mono coil (12x15) for an original Minelab, and it gave me the measurement (300uH).
So I made sure that
Please, dear Woody, where is the glitch?
Hello First, thanks for all the valuable information that you share with us I have a question please help me I want to make a GPX file, not a small file, at least 30 inches, but I don't know much about measuring resistance, hertz, and others. I had an idea and before implementing it I want an answer from you If you take two coils, for example, two coils of 18, and remove the wires and connect them to each other, and create a disk of 18 x 2 = 36 Will it work ^^ Just connect the wire of the two disks to each other and understand in a circle the size of the disks whether it works or not Thank you very much If it does not work, I hope that you have a fixed table for a specific number of turns and a specific thickness of the wire for a diameter greater than 20 inches. Please advise me, thank you very much.
Coils in series or parallel have to be made, it will not work by joining two commercial coils together. Seems like i will be making another video.
^^ Even if I removed the wires from the coil and wrapped them myself again, but with a diameter equal to the diameter of two coils together instead of 18 inches, the coil would be 36 inches and with the same number of turns in the 18 inch coil. Nexus 32 or 42 inch is too expensive, and if you can make a cable disk only without the external structure, I will buy it from you. Thank you very much for your cooperation and good treatment
It will work but it is not linear, you will only need to add only a couple of more turns, also it is not good to solder litz wire on a winding, if you do solder, put a small ferrite sleeve over the join.
@@DetectorMods thnx allot
I will try thnx man
I make one ^^ it’s work
35 Inch Henry = 27m H and the resistance is 0.76 When it approaches the ground, it makes a noise. Should the graphite coating be on all the disk? Is there any support ^^
note When I put my fingers on the metal buttons of the device, it makes a loud noise
Hello there
Would you be interested in making me a 3 meter coil
If there is such a beast
I am looking for something 5 plus feet down
Now
I do not know if this is Even possible
Do to my lack of knowledge in this field
Kind Regards
Kelly
Contact Dave at Detectormods.com he makes huge coils.
Boa informação
Hi...about cabel of coil what made from? I mean what element get in cabel ..... thanks☺️
Cable for the coil has to be made from insulated strands of copper wire , Litz wire, the inside centre core and the outside shielding as a spiral wind , this type of cable is used in medical ECG and TV studio camera video cable.
@@DetectorMods thank you so much so much so much .....did you konw .no one has informatiom like what did all iducation station media or youtube or facbook ...ect .) like what you has in formation about detector metal ....however .. thanks thanks 🕴️🕴️🕴️🕴️🕴️🕴️
Begitulah mono coil, saya sudah mencoba membuat sendiri coil untuk mesin gdx8000 china , mulai dari ukuran kecil sampai ukuran besar dan semua bisa digunakan🙏
Yes.
Tuan yang baik, coba anda membahas dan mempelajari tentang coil DOD yang di pakai gpz7000 untuk di pakai di gpx4500 ,vpx5000 , apakah itu akan lebih bagus penggunaanya di lapangan berbatu panas 🙏🙏🙏
People do not realise that the GPX 4500 and 5000 have 2 separate input channels and separate transmitter all on the coil plug, so easy to build centre transmitter and two separate receiver coils, you can 180 phase swap one receiver coil for excellent noise cancellation.
@@DetectorMods thanks for the enlightenment, I hope you make an experiment about it and will be able to contribute to hunters having trouble, thanks
