The M-48 MOD-1 is the next generation of the popular original M-48 mask.
It still features the unique 2-cavity design. This allows the lower pod to be removed while topside to conserve air, and allows normal speech while diving. It may also be used with a variety of different communication systems.
The lower pod is also removable under water to allow making gas switches, and to share gas in the event of an emergency. The evolution of the mask has given way to a dramatic increase in visibility, an improved buckle system, 5 leg straps, a mechanical equalizing device, and a variety of options for mounting external components, (lights, cameras etc.).
All of the components have been strengthened to bring this mask to a commercial level of ruggedness you will not find in ANY other lightweight full face mask. Future innovations for the mask are underway and because this mask has many available mounting options, it will be able to accept new components by Kirby Morgan, thus making it truly MODULAR.

Regulator - The MOD-1 purchased with a balanced SCUBA 2nd stage demand regulator. If your mask was not supplied with a KMDSI regulator installed by the factory, you will need to have an acceptable regulator installed in the pod.
CR Standards - These masks meet or exceeds all standards established by Dive Lab of Panama City, Florida, and are CR (Commercially Rated) marked.
Surface-Supplied Open Circuit - The mask should only be used for surface-supplied diving by divers trained and qualified in surface-supplied techniques and procedures. A fully functional emergency gas supply system and body harness must always be used when diving the Mod-1 or any of the KMDSI full-face masks models in the surface-supplied mode. When using this mask in countries that conform to CE standards the mask must only be used with components that have been CE certified. The maximum recommended recreational diving depth for the Mod-1 with open circuit scuba is 130 FSW (39 msw).
