OTS Guardian Full Face Mask

The Guardian line of Full-Face Masks (FFM) is OTS' most recent innovation. Designed to meet the demanding needs of today's Commercial/Professional Diver, it leverages the best features found on other FFMs with unique features designed by OTS.

The second stage regulator is horizontally mounted close to the diver’s face. This design minimizes the difference in ambient pressure exerted on the second stage diaphragm and on the diver’s body irrespective of the diver’s position—eliminating the need for manual adjustments.
