Two different days at a lake beach with the Scuba Tector. First day, few finds, chased off by thunderstorm after an hour of hunting. Day 2, more finds after about 2 1/2 hrs. Visibility zero. All had to be done by feel, which actually was kind of fun. Exception was the kids that would throw rocks on my back and tap me on the back to make sure I was alive. The full-face snorkel mask draws alot of attention, as does my stationary body in the water as I retrieve an object. Gold remains elusive. I scored a pair of sunglasses and eye mask though. As I scanned the bottom, I just felt my hand hit them.
