What do you think of Excalibur II vs Deus II for 10-50m depth saltwater corroded metal and precious metals detection?The XP DEUS II has a rating of 66ft....Bone conduction headphones which are a game changer under water. I have used the Excalibur too....What type of diving detecting are you doing? Here is a video of the Deus II in action...I test , teach and review Metal Detectors for companies.
