Welcome to the forum Jim. I've got the Big Foot and LOVE it for school yards, etc. With the MXT's Big Foot, the back of it will double beep and the front half will only beep once when there's a target. When you have your target in the front half of your coil, swing it back and forth until you know the center of the target with trigger pulled.......push the coil forword until it stops shouting at you. Your target will be exactly in the middle of the coil where the rod is attached. EASY and I love it. Or when you find the target, pull trigger back, listen for the loudest signal, pull your coil back and when the signal stops, it's at the center front of your coil. Takes a bit of practice, but you can pinpoint an object so easy with the Big Foot coil. Usually 9 times out of 10, I can take my probe and hit the coin with the first approach to pinpointing (only use it for cladding). Good luck and enjoy your new toy.
