found out something else today with my safari first off i dug a few IHs in very nice shape!!! and some trash ,this one area i tried to pinpoint a target and i kept getting this pulsing sound it seamed like it was about 2' long i thought something was wrong with the detector but i had to dig anyway to see there was anything in the hole and it was a power line for the outside lights they had going to the driveway ,i never knew the detector would pulse on a live power line in pinpoint mode, i think that is good to know ,has anyone else ever noticed this??
