The Periscopic Mask – is an upgrade from the wide variety of existing leisure full-face masks to a new class device of adventure, sport, and rescue. We shifted the tube to the left and inserted two mirrors – in the top of the tube and on the glass inside the mask above the left eye. We made more than a dozen modifications to fix the safety errors that are in ALL other masks created before the Periscopic Mask. We added to the mask an adapter for a mini air-tank & made it suitable for a speed.
Our mask operates in three distinct modes:
Snorkeling – no air tank, depth up to 20 feet;
Adjacent – air tank attached, depth up to 3 feet;
Diving – for certified divers, air tank attached, depth up to 33 feet.
