Enjoy the results... It works clear, reliable and trustworthy!... So go ahead ...

At least you know the Admiral scheme works . I have personally made many schemes that I have found on the net and they do not work.
And if in this forum you can not find information on how to make a metal detector, then this hobby is not for you
Here you have a working circuit, ready PCB, data about the coil and proof that the device works I don't know what else you want maybe someone can do it for you?
I don't want to show off. but I have already made three Admirals thank the colleagues in this forum for which I'm thankful.

Hi folks
To be honest, personally I don't see any help here, only I saw videos of well constructed Admiral detectors by the members, instead of that, I will be appreciate if there is a conclusion of the experiment you realized, like a photos of the PCB done by (CEBRAIL, berntre-one ) and one answer only about the coil TX and RX, which one shield ??? ... Or both shielded and the chosen cable from the coil to the PCB. This will make the work easier to the other members to develop it and share the experience, not sharing what we done only by videos of working MDs . Sorry for being critical in a bed way, but I though this is the only way to share our hobby with the others. Thank you

I am agree with you 100%

Hello
25-28cm air test but if you set it up well you can hear it in the ground on that depth
I posted video on page 9 air test with my Admiral

[Zotchin]

Hi all
Is there an explanation video
I see many videos of metal detectors making but this no.

[Zotchin]

thanks for your help getsa Can you tell me what is the normal depth of the device? For example a 1 euro coin.To know the capabilities of the device. now catches them at 25-28 cm. Thanks again

Hi
25-28 in the air or in the ground?

[tchaikovski]

Same Question as

Zotchin

mentioned !!! Thank you

[Zotchin]

tx 10.35 volt rx 47milivolt 8.5khz

How did you rich 10 volts or without coil connected?
Another question when using oscilloscope to balance rx
Where can I attache the probe ? After or before connecting rx coil?
Thank you.

[CEBRAIL]

yes i have underground tests very good depth

[Emersonpaz]

Excellent results
CEBRAIL congratulations I was impressed with the detection distance. have you tested it in the field?
