Thank you for sharing information about admiral metal detector ,I also make the admiral but have a lot number of problems .

I forgot to mention that when the coils are nulling the oscilloscope is connected to pin 1 of the TL072. Greetings

Can I make a coil to my Garrett ATX, just for fun?
Can I make a singel coil, not a DD coil

[@pirusyasayesh5178]

Please help me
What was the diameter of the circle of the coils?
Show on the paper how to wire the coils on the cable
Learn how to adjust volumes to remove different the metals.
I tried a lot and still did not remove the ferrite :-( . because I am a beginner

[@HoBByTV_The_King_Detectors]

Coils diameter is 20cm circle & about cable I have video on this topic.I recommend you watch it

[@homeelectronic1775]

Hello. I made your circuit according to the swimming video, but the sine wave at both ends of my coil has some jumps, can you guide me where the problem is. Thankful

[@HoBByTV_The_King_Detectors]

You can send me pictures on Facebook to see what I can do :) Greetings!

@@HoBByTV_The_King_Detectors Hello . thanks for your response . The purpose of using a larger coil is to explore more depth. is it possible

[@HoBByTV_The_King_Detectors]

Yes ;)

[@homeelectronic1775]

@@HoBByTV_The_King_Detectors I sent a photo on Facebook. Thank you for your guidance and if I use a larger coil, what changes should be made in the circuit, frequency and number of turns of the coil. Thankful.

[@HoBByTV_The_King_Detectors]

I saw it, but apparently the coil you are trying is not correct because you should have about 8 Khz. Try with with the exact parameters TX 1mH is important. And recheck any solder joints on the TX circuit and is it right

[@homeelectronic1775]

Hello. If I want to use a larger coil, what changes should I make in the TX circuit? Thankful

[@HoBByTV_The_King_Detectors]

Hi! No need to change circuit just the searching coil has to be with TX - 1mH & RX between 7-12mH

What type cable did you use from coil to the board? And where can I buy?

[@HoBByTV_The_King_Detectors]

UL2547 Signal Shielded Cable, 20AWG

[@HoBByTV_The_King_Detectors]

you can buy it from Aliexpress

Свързан ли е паралелният кондензатор на бобината на приемника (RX) към краищата на бобината?

[@HoBByTV_The_King_Detectors]

Не не съм свързал паралелен кондензатор на RX.

Пиши ми във Фейсбук и ми прати схемата по която си направил платката да я разгледам.

How you make two tons?

I just posted in Facebook & Instagram part of schematic which is 2 tone mod. You can see there. greetings
