ahmdi, детектор работает с двумя катушками. Две катушки можно вставить в один корпус. The detector works with two coils. Two coils can be inserted in one box.
ahmdi, I also did the CHANCE-03 scheme with the changes. Changed the circuit and looked for another design of the coils. The information is posted on the forum. Please answer, what changes did you make in the scheme? And why?
