Unlike many other Full Face Masks (FFMs) which are modified gas masks, the Apeks Full Face Mask was designed for diving from the ground up. Our design leverages the best features found on other FFMs with unique added features.
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.
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.
