[QUOTE="PhaseTech, post: 518591, member: 3149"] Wet sand is like a big conductive target, the less you see of it, the better the detector can handle it. So most often than not, a smaller coil is less affected by the salt than a larger coil. A small concentric is going to be better than a big DD, but a small DD would be even better. But then if you go too small, you physically can't get the depth. In saying all that, the best compromise between depth and stability I could get out of a 505 was to use the 10.5" round DD in 18.75 kHz. And as Goldpick said, this is key to stability "You will also need to run the coil off the beach surface by an inch or two, especially on the wet sand or you may get excessive falsing." [/QUOTE]
