Hello! I made TH version but heve some trouble. The detector work fine. Good GEB and DISC. The coil is from Wave, frequency 8kHz. balanced- 50mV on pin 1 4053. The problem is depth... about 20-25 sm for 1 euro coin in air. Treshold is nice. Where could be the problem?

@ Lubo
how much is tx amplitude? and what diameter is your coil?

[Lubo-BG]

26Vpp coil is dd 32sm

thanks

Hi Ivica, is there any chance to be adapted Tesoro Cibola/Vaquero coil? I mean SEF 12x10
I think to order one in next 7 days, but i wan't if cannot work on this machine.
Cibola inductance are 0.95mH for TX and 15mH for RX. How to calculate right capacitor tank?

Had some PCB's made up of "mag_redu_pcb" version:using 1206 sized SMD components.
Should arrive this week Tuesday.
I have been studying the schematics and PCB layout this morning.
