if you cannot ground balance it? I received one, took it to the beach and couldn't ground balance it at all. I tried several places from high, dry sand to low wet sand and in between with no luck. I tried hunting in all metal mode for a little while anyway but it was noisy and when it did hit targets it often gave false I.D. lights on the target. Trying it in disc mode was even more noisy. I was digging bobbie pins and fish hooks that were giving good, solid yellow and green lights. I thought the west coast was where the problems were but I guess we have our share of black sand here too. Anyway, I've sent it back and hope that they will let me upgrade to the Excal without having to pay outrageous re-stocking fees as I do believe there is more wrong with this unit than just the ground balancing issue. I have never had these kinds of problems with my Sov GT. I purrs like a kitten and doesn't skip a beat no matter where you go. --Jerry
