Ocean Reef G. Divers Underwater Receiving Unit

The M101A G.divers is a receive-only unit operating on one channel. The M101A fits on any standard mask strap, conventional masks or full face models. It might be handled and shared by more divers thanks to the high quality speaker.  The M101A’s reception is so strong that , infact, it is not always 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 (dependent upon environmental conditions and distance). 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 unit’s total battery is approximately  30 hours.
