I got for gwe hours coil from Polish PI detector - SMETAK HS-3 and i check this out.
That coil has small coil inside and bigger outside like dualfield coil but in the plug there was 5 pins. With ihm meter i chesk one has 5ohm and the second 65 ohm resistance. The fifth pin i think is for gnd shield on the cable.
I think 5 ohm coil is the TX and 65 ohm coils - RX and my question is which is small one and which is big one. Small is located in center of the bigest one.
Unfortunetly i did'nt check inductance of them.
