Any wireless metal detector technology can’t work under water. It would be OK if it were just the headphones as you can always use the wired ones. But what is to be done when the machine has a wireless coil? Right you are, you should add a few cables to the coil and make an antenna. Here’s a photo review: how to fit the coil antenna for underwater search to your XP Deus. Plus, have you ever seen the XP underwater headphones? These ones look unusual. It seems to me it’s not really the original accessory, and the chances are you can find the aftermarket ones too, as well as a waterproof remote control cover.
All about the XP Deus metal detector is collected here. Besides, there is a series of posts related to an underwater XP Deus. On Knowledgebase pages there is also additional information divided into special sections – search coils for the XP Deus, repair and updating, tests on gold and brick, a depth test and comparisons of all sorts, user manual and much more. Happy hunting to all (and no winter for us!)!
