A great machine, don't think you will be sorry for buying one. Make sure you get a good set of headphones, this is must. I beach hunt with it and a cz20, my 20 will not pick up the small gold like the MXT so I use it to water hunt. I would recommend getting a 6x10 DD coil, this is my choice beach hunting. The MXT will hunt the wet sand with no problem provided that you re-balance going from dry to wet. The way I do it is to ground balance in the salt position then lock your setting. Do the same going from wet to dry only ground balance in the ground position on dry, then to lock. Bottle caps can be frustrating for a while, but they will generally bounce around on the vdi reading. A coin tends to lock on solid with a lighter sound than a ring, the rings will lock on solid too. Don't run your disc. to high, I would not go over 2. Just take your time, don't rush, learn the machine. It will pay off. hopes this helps some. will be looking forward to seeing some of your finds.
