O.K. Right now there are no waterproof headphones for the AT Pro. The infinium phones that Garrett will use do not work because they will not turn of the speaker function as yet. So don't buy a set of infinium headphones thinking they will work properly, they won't. Garrett is correcting the problem and should have the new phones ready when the release date comes up for the AT Pro. No dealer has them in stock, they haven't been released yet. The dry phones that come with the unit are waterproof at the detector so they can be used as long as you don't dunk the actual headphones. We'll just have to be patient, they'll get it right I'm sure.
