The M101A is a receive-only unit operating on the same frequency as the GSM units, M105 units, and any previous Ocean REEF communication systems. The M101A fits on any standard mask strap, conventional masks or full face models. The unit automatically activates upon contact with the water. The M101A uses a 9v alkaline battery and has a “low battery” alarm which beeps every 30 seconds when the battery is low. The M101A’s reception is so strong that it is not necessary to attach it to the mask strap. A diver may hold the unit or attach it to a BC, allowing other divers to listen to the transmission.
