I purchased a used Surfmaster PI which already had the modification done to it. It is more sensitive to small gold but it also seems to be more sensitive to salt water. It signals any time that I move the coil off the bottom or if a wave goes over the coil. Is this normal? I can eliminate this problem by adjusting the pulse delay control but I wonder if I am then loosing sensitivity to small gold?
