I am looking into buying a Garrett AT PRO. I presently have a Minelab E-Trac and It's a great detector but I'm looking for one to use in shallow water. I'm told that they do pretty good in the wet salt water sand. My E-Trac does very well in the salt water but if I drop it in a few inches of salt water it becomes a very expensive paper weight. Would be a bad day indeed. Can I get some advise from AT Pro owners. Positive or negative..Thanx a bunch..Joe B.,
