I decided with the warm weather coming to buy a set of the underwater headphones to use in the water with my AT PRO. I saw a deal and went for it. They came today and I hooked them up and they don't work. The sound still comes out of the detector NOT out of the headphones! I called Garrett right away and was told they are on back order for at least 2 WEEKS(maybe longer). I call the person I bought them from and he was more then happy to refunds my money plus the shipping cost back to him, but I would still be out of headphones!!( he had know more) so I decided to wait it out for Garrett to get new ones in and exchange them.Now I found out that the EARLIER water headphones don't work on the AT PRO although they're all have the same connectors. Go figure!! It's going to be a long 2 weeks or more. water season is getting close!!!
