Hi all, first time on this site. I'm new to detecting -recent retiree and close to Long Island sound in CT so I thought this would be fun. I have been out a few times with my ATPRO and so frustrated I am ready to chuck it into the ocean. It beeps at everything. I adjusted the sensitivity, and then it doesn't beep at all. I read saltwater is a problem for theses detectors, but I'm using it on the sand. And I read that black sand can be a problem, but I am using the ground balance and still no luck. I've tried the STD settings and the PRO settings. So far I'm not having any fun. Any users out there that can make some suggestion?
