I use an MXT here at Va Beach without problem. I have used the 6x10 coil, but have also used both the stock and even the new S12 coil with success. I can also run the sensitivity at max most of the time down in the wet sand. The most important thing is to ground balance properly. Just pump the coil up and down over the area you want to hunt until it quiets down. If you tend to wander away from that type of sand, it may get chattery and you'll need to rebalance. Also, if the water comes up and laps over the coil it will likely give you false chatter. Its just not meant to hunt in the water. You'll have to get another machine more suited for that environment if that's the case. I also hunt in salt mode with disc set to "3" or a little below. I have no problem picking up low conductivity targets (foil, etc) with that setting. Hope this helps, and good luck to you ..... Bill
