Got back from my trip to San Diego and thought I'd share some of my trip with everyone. My MXT cratered while I was there and I had to send it back for testing. The coil went bad after about 6 hours of use and when you turned the machine on it went directly to overload and really screamed in your ear. They tested it and put a brand new coil on it for me. I did have a great time with it on the beach and that 12" coil is a humdinger and a nickel killer. In the 6 hours I used it I found 29 quarters,13 dimes, 21 nickels, 32 pennys of which one was a 1948D, and 1-1953 20 Franc piece, 4 rings, 3 earrings, a Chargers dog tag and a host of other beach things. I am going to buy some other coils but that 12" coil is a dandy and has great depth. Wet sand and dry sand, it worked well but does not like salt water and black sand combo. Here's a few pics. Thanks for looking. Shooter65
