The red 20-meter waterproof cap is reserved exclusively for underwater use with the DEUS II remote and features a pressure-balancing mechanism that prevents the flexible keypad from swelling and the loudspeaker from sticking during submerged detecting sessions. The cap maintains pressure balance to a maximum depth of 20 meters (65 feet), covering rivers, lakes, and coastal zones where recreational underwater metal detecting occurs. After each underwater hunt, remove the red cap immediately and replace it with the standard land cap before resuming surface detecting or storing the remote, as temperature variations on land will cause component distortion if the red cap remains installed.
