OTS Guardian Full Face Mask

The Guardian line of Full-Face Masks (FFMs) 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 Guardian FFM comes in the following colour combinations (skirt/hardware): black/black, black/blue, black/red, black/pink, blue/black, and yellow/black.

Take your underwater communication, comfort, and safety to the next level with the OTS Guardian Full Face Mask. Designed by Ocean Technology Systems (OTS), the Guardian is a lightweight, low-volume full face mask that delivers exceptional visibility, natural breathing, and reliable performance for recreational, commercial, public safety, and scientific divers.

Unlike traditional scuba masks and regulators, the Guardian covers the entire face, allowing divers to breathe naturally through both the nose and mouth while keeping the face protected from cold, contaminated, or irritating water. Its advanced design reduces jaw fatigue, increases comfort on long dives, and provides a secure, watertight seal for a wide range of face shapes.

The Guardian is also communication-ready, making it an excellent choice for divers who require underwater communications systems for training, professional operations, or team diving activities. The large panoramic lens offers an expansive field of vision, helping divers maintain better situational awareness and confidence underwater.

Whether you’re exploring reefs, conducting inspections, or working in demanding underwater environments, the OTS Guardian Full Face Mask provides the comfort, protection, and performance serious divers demand.
