The M-48 Mod 1 is the next generation of the original M-48 mask. It still features the unique two-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 unit with regulator features the same as the original M-48, the adjustable 2nd stage scuba regulator (p/n 305-166).
The lower pod is also removable underwater 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, five 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.
Ships with log book and pen (p/n 125-001), air inlet swivel (p/n 305-017), and carrying bag (p/n 800-905).
Before attempting any diving in any type of contaminated water, a complete diving and topside course in hazardous materials emergencies should be completed. The divers and the topside team must be properly trained and have the proper safety equipment. All helmets and suits can leak water under certain conditions. Divers should use extreme caution when diving in contaminated waters.
