On the previous page, CEBRAIL posted several videos of the device's operation, everything works fine for me. If you want to throw the board away, I have no advice on this.

Hi again, I have a headache of trying and trying, well i tried everything, in my case i connected S1.2 with S1.1 this is two tone separation i heard low pitch of ferros i guess//black metal// and S1.2 with S1.3 mono tone, it means All metal right ??? Please i think if this board not work i will throught it away

Hello againe nikko10, sorry for bothering you againe, i removed the Transistor you highlited but it remains the same, i will check the voltage in TX and RX and i will poste it here, please if you need any further information to check in, keep me informed. Thank you

[nikko10]

if the parts are intact, it works without problems

My problem nikko10 is only my admiral can sense ferros metal everything is working great with your help, no sense of gold, alluminium, bronze .... nothing, just feeros metal, i am going to try to change the 330nf cap next to TX coil maybe it will work

I tried it but no chance at all, there is no cut out black metal in monotone, this is why makes me so confused ... ? !!!

[nikko10]

With the "Discrim" knob, you need to cut out black metal so that it cannot be heard in monotone mode, then switch to two-tone and a second tone appears.

Thank you nikko10 for help finaly it works and insane sensibility but only on metal ferros, no sense on the other metal at all, i solder all the highlited white correction in the PCB you offered even the TL072 on top left. Now i am confused

Admiral with two tones not working, because there is a missing part in PCB

Hey fellas,
Sorry my English is not good enough, well i built the first admiral version and it works great in Air, i didn t tested yet in field but is seems work properly, and i decided to build the Admiral 3 as they called, (With two tones), not working how:
Audio working great (Pot)
Threshold aslo working, when i try to adjust the pot in 1/3 turn it continues making continues sound, i think it is working but without sense at all
Disk and the GEB i dont know because there is no sensivity at all obviously
Where is the problem mmm, this is way i ask you guys for help
I check 6 times the PCB but no luck, mey be if i have the Schematic it will help a lot for maybe a missing part as i highlited with yellow color in PCB exactly in 47K resistor.

yes nikko10 admiral performance is very good in soil, if the coil values are good, it is very good in soil
