All metal sounding off on every swing ????

My F75 picks up my Garrett Pro-pointer, when I switch the Probe on ,or off,,, I can hear it click in my headphones,, it is EMI,, but once I have located what I am probing for ,and resume my Tectin,, I just GB again, and off I go,, its bound to pick up the EMI of the probe once its switched on, as both are very sensitive,, but it should'nt be a problem to your hunting, or your depth, when its off,,,I think mostly its knowing your machine, and what settings work best, for the ground ,location, and weather conditions your in ,on any said day,, Oh yes,, ya should never try to airtest your detector, either in, a house, or anywhere for that matter,,. Too much EMI in a house in the first place,, and secondly,,, How can you "Airtest" a detector you have to "Groundbalance" before you Hunt???? ..Ludicrous...Or What??? ...Happy Hunting....Kuffy
