Design, functionality & construction
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.
