Kirby Morgan does not make a vacuum controlled test device for our one way valves (555-195). This device was used back in the 1980s (not made by Kirby Morgan) but this tester was phased out long ago. Vacuum controlled one way valve testers are not necessary and are no longer commercially available for our equipment. The current and approved method for testing the one way valve is covered in the Kirby Morgan Owners Operations & Maintenance Manuals.

Kirby Morgan helmets are heavy duty professional life support equipment and are not intended for use with a self-contained gas supply (not intended for SCUBA use). There is no provision for surface swimming once the SCUBA air supply is depleted. This could lead to serious injury or death by suffocation or drowning. We are sorry but Kirby Morgan does not offer a light weight, recreational diving helmet that would keep the ears dry.

The SuperMask® was designed with multiple gas switches in mind. When the pod is removed, you can use any second stage regulator, or you can mount a second pod with another second stage to the mask. This can be during the dive or when hanging in deco on a surface supplied deco gas or from bottles at the deco stops. When using a surface-supplied gas, having a pod mounted to the second stage allows for hard wired communications to the surface.

The removable pod enables you to handle all out of air situations. Simply unlatch and remove pod and use your alternative air source, octopus, bailout system or buddy breathing to the surface.

Many of todays most popular regulators can easily be mounted to the SuperMask® pod. However, due to a wide variety of manufacturing specs, some regulators do not fit. Please see the regulator section.

The M48 SuperMask & M48 MOD 1 do not automatically come with regulators.  This depends on the POD chosen.  The customer chooses a Mask (SuperMask or MOD 1) and chooses a POD.  Any POD goes with any Mask.  The three main SCUBA PODs are:

1. 805-015 SCUBA POD with Tilt to Purge
2. 805-026 SCUBA POD with Balanced Purge Tube
3. 200-130 SCUBA POD with Balanced SCUBA Regulator installed

If you require the regulator, order POD part no. 200-130 to go with the Mask of your choice.

With the SuperMask® there is no need to keep the mouthpiece constantly clamped in your mouth during the dive. This makes your dive very comfortable, no jaw fatigue on long dives such as cave penetrations or prolonged decompression times, especially with the larger rebreather hoses.

This mask has a remarkable fit. Not only does it fit most people, including those with small faces, but also most people with facial hair such as beards and mustaches.

You must be a certified scuba diver and should be completely familiar with all the operational features of the mask before diving it in open water. It is recommended that you first dive in a calm, clear body of water such as a swimming pool, if possible, to become completely familiar with all the operational features of the mask. While it's operation is not complicated, the diver should be able to adjust the regulator for optimal breathing as well as unmount, mount and clear the pod.

The masks can be configured to use various wireless and hard wire communications systems. We do not sell the communications hardware. Ask us for recommendations on communications.
