I use it at the beach here in Ca all the time. I have two custom programs, one a modification of the "jewelry and beach" program, and the other using mixed mode. Mixed mode is a bit of a noisemaker, but it adds some depth when hunting in the wet mineralized sand. Like a previous poster, I prefer using it with the bigfoot coil. The standard 9 1/2 inch coil will work, though, but it's a bit harder to get rid of the false responses and still keep a decent depth. Don't know why this is the case because the standard coil is a deeper seeking coil in non-mineralized soil conditions. I use the XLT with the bigfoot mostly in the dry sand. If I'm going to do any serious wet-sand detecting, I'll opt for one of my pulse induction machines. So, will it work? Yes. Is it the best machine for saltwater beaches? Definitely not. But unless you are into the hobby enough to have invested in a stable of detectors to cover different situations, the XLT is, IMHO, the best all-around detector available when you consider functionality, reliability, availability of different coils, and price.
