Having used the Impact in very highly mineralised ground since May I have been extremely impressed by its stability to handle hot ground.The only times it overloaded was in extreme mineralisation (100% reading on the meter).I am also impressed with DEEP mode as it goes at least twice as deep as the GEN mode on larger objects.GEN mode at 20 Khz is very sensitive to small objects of 0.1 gram in size and much better at pinpointing.Anyone interested in prospecting for gold will find the Impact as a very capable detector for the money.
