Guardian Full Face Mask w/ ABV

Our Price: $798.00

The Guardian line of Full-Face Masks (FFMs) is OTS’ most recent innovation. Unlike many other FFMs which are modified gas masks, the Guardian was designed for diving from the ground up. Our design leverages the best features found on other FFMs with unique added features designed by OTS.

The second stage 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.

A locking mechanism secures the second stage to the mask to allow removal for post-dive cleaning and storage. As a safety precaution, the locking mechanism is located inside the mask to prevent accidental release during diving.

Another noteworthy design feature is the use of a double face seal. This allows a single mask to fit more faces. No more use of rubber tubing to fit smaller faces, measuring faces to order the right size FFM, or not being able to share masks amongst large and smaller faced divers.

Mask Bag and Hose included!

AGA, Interspiro Divator MKII Full Face Mask

Our Price: $799.00

The Interspiro line of diving full-face masks (FFMs) are high quality masks and have been field proven by Government, Military, Commercial & Public Safety Teams around the world. The FFMs are primarily used with scuba, but are often utilized with surface supplied gas as well as rebreathers.

The Divator II has been tested by Duke University to 1,800 feet (unmanned test) and found to be extremely reliable. Many professional divers around the world choose the AGA FFM. With the addition of our OTS Ambient Breathing Valve (ABV-1), standby divers as well as divers on the surface can effortlessly conserve their gas supplies by breathing surrounding air through the ABV.

All the Interspiro full-face masks have been tested by the U.S. Navy Experimental Diving Unit (NEDU) and are Approved for Naval Use.

Underwater communication is achieved by the addition of an Ear/Microphone Assembly (not included), which allows for through-water communications when paired with a communications unit like the SSB-2010, or hard-wire communications via the CR-4 ComRope. Alternatively, for a more compact/less expensive option, a Buddy Phone can be installed on the FFM for through-water communications.
