![]() 2Khz is not good frequency for my project because i need very long antenna. The schema of receiver that you attached is good but not for 100Khz. It need more stages so to keep the same gain (100 for every op.amp). Regards ![]()

You can use the electromagnetic antenna in outpou amp or use loop antenna.It does not take a very long antenna.It is suitable for the detection of frq 50 hz to 500kh . 50hz for very deep and big goals and 500kh for normal deep and big or small goals.I built a transmitter and receiver, and it works well.I used the antenna coil. I receive signals from a distance of 50 meters.I have not yet tested for metals., But I believe that this method is effective.my transmitter working in 4.5kh G.L

By the generators and frequency meters Here, the detector can be a good outlet

OK, but how you know which frequency is set? You need here additional frequency counter.
