Hello Electrosoft and Apocalypto . When you build a PI Circuit , first build a standard basic mono search coil !! Start with a 8 inch diameter , use 0.38 mm wire @ 28 turns that should give you close to 400 uh [micro-henry] inductance and around 2.8 ohms dc resistance . Then you can Test to see if your PI circuit is working properly !! Small euro coin should be detected easily at 12 inches [30.5 cm] in the ground . Then you can experiment with building larger searrch coils . Make sure your circuit is working perfect first , then play with much bigger coils . Always Remember , Do not go below 2.0 ohms DC resistance on any size search coil or you will damage Q1 IRF 740 on Delta Pulse .
Regards......Eugene
