Hey all. Bought the Excal 2 from Demarco Detectors. What an awesome guy. Called me twice to answer questions. Just a stand up dude. Took her out this morning. Have some questions. This is what I was searching on:descriminate 4, sens 6, disc on. Pulled alot of bottle caps in waist deep water. One question. The machine seemed to now and again catch a high signal or almost thresh hold, and stay at that tone until it seemed to pick up another target, then it would switch to another tone? Also, I tried doing some dry sand hunting. Weird. Lots of signals, but hard to get solid ones? Found a new penny on the top of the beach, and went over it, kind of weird. I'm not sure I would know a solid quarter if I hit it. Does in hit loud and solid on dry beach? Should I use pin point on dry beach? Dug about 25 or thirty bottle caps in the water, just trying to get used to it. Des in Buffalo
