But main question here is ; can we detect/locate it at long distances? I never succed that, neither anybody else i know. That is the problem.

Ivconic, look, don't know in reality what happens, but is possible with no much sensitive method cover 5 meters, but deppend what system you use. The more long I "invent" was capable to find treasure of all silver items at 70 m and at depth only 70 cm. With this sensitive system, electric lines are problem. If you isolate, don't detect or distance is "short". This system use as input CA3046 array transistors, with gain 1,000 times and 1 uA sensibility. Of course, this is not the only circuit. The signal out of the CA3046 go to a stretcher based on 741. Output of this go to the beep generator, any stage with independent battery, this is important.
