Which one is J1-1 and J1-2?

Is this right?

J1-1 is the left one
J1-2 is the right one

J2-1 is the upper one
J2-2 is the lower one

J1-1 is right
J2-1 is bottom or you can reverse it if you make double beep when test, its depending on TX RX coil placement,

I got about 30 cm. 25 with dicrimination 1 Euro coin.

[BKY1337]

This was with 22cm coil instead of 27cm, because i printed the template like it was in the pdf
and i haven't noticed that its smaller as it should be.

I needed about 124 and 119 Windings for the coil. If someone wants to make this coil use 128 and 125 and remove windings till you
get the right frequency.

I think 30-32 cm is very good for this size of coil.

I made a new coil, the 255mm one.

My resonances are 14,27 kHz and 13,51 kHz.

Everything works, i have more than 30cm for a 1 euro coin, over 50cm for scissors and maybe 1m for a coke can.
But i cant get a signal for a big aluminium pan. It was a teflon coated pan, but i cant get a tone for an other pan too.

Disc works, rejected ferrite and iron, and i can get 35 cm for a 1 euro coin. Its just 30-32 without disc because i have to turn the sense back because i have side signals.

But i have the problem with the big things like a pan. A stainless steel thermo bottle gave a signal at 1m depht.

I have another problem too , i loose depth when i put an isolating layer over the shield. Is this normal? I had this before with my smaller coil and i planned
to leave the coils like they are and put epoxy over them.

What does it mean "isolating layer" ?

[BKY1337]

I mean the tape layer after the shield. I have already made the isolating layer with thin ''tesa'' brand tape.
The problem is still present. It just does not detect the large pans (about 35cm diameter).

[BKY1337]

It works now, maybe it was the lamp hanging from above over the coil.

[BKY1337]

I have a problem with my detector. I have finished my build and found a toy gun and a lead seal from a flour bag.
Then the detector didnt work. I thought its the battery but its full. I have only a depht from 5cm for a coke can.
I dont know what happened. The detector detects metal when i sweep it over the PCB. Is this normal? I dont know how it was before.
I hope its not the coil.

[BKY1337]

I solved the problem , a cable broke at the solder point inside the connector plug.
