I tried mine once at Carrabelle beach. I found lots of clad. It was winter time (off season for beaches), and detectorists do hunt this beach, so that's probably why I only found clad. It was a treat though...the detector worked just fine, no complaints. Not much trash either. I'm no expert, but I think the CZ7 is ideal for beach hunting. My wife didn't find so much. Oh, we didn't go into the water either. Too cold.
