If you're going to detect in salt water or wet salt water sand and you want discrimination (and not go crazy digging iron targets) you need to get a multifrequency machine. The only one on the market that is also a great turf machine, is the Minelab CTX. All of the other salt water machines (Fisher CZ series, Minelab Excalibur, White's Beachhunter I.D.) aren't ideal for turf hunting for a variety of reasons......I.E. no TID or depth reading, and they're usually heavy and not well balanced. Now, if you're not going any deeper in the water than your knees, you could get away with a Minelab Sovereign, Explorer, or E-trac also. All three of those are excellent in wet salt sand and in a turf hunt.
