Ocean Reef M-101A GDivers Underwater Receiving Unit is a receive-only unit operating on one channel. The Ocean Reef M-101A GDivers Underwater Receiving Unit fits on any conventional mask strap or full-face mask models. It might be held and shared by more divers thanks to the high-quality speaker. The M101A's reception is so strong that, in fact, 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 Ocean Reef M-101A GDivers Underwater Receiving Unit automatically activates upon contact with the water. The Ocean Reef M-101A GDivers Underwater Receiving Unit 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 life is approximately 30 hours and is depth rated for 120' (40 meters) with an operational range of 600' (200 meters). Product comes with an owner's manual.

Ocean Reef M-101A GDivers Underwater Receiving Unit Optional Upgrades:
Add a Damper - When Communicating underwater at short distance or in closed environments, it is often possible that audio distortion is caused by excessive transmission strength. The transmitters are relatively powerful and if they are used in a pool of very close to each other, distortion can be created. The audio goes "off the scale", and becomes difficult to understand. The Damper can be inserted on the antenna; it is made of a spongy material with many tiny air pockets. The combination of the two materials creates the filter needed to reduce the transmission power as needed and makes conversation intelligible again.


Add an additional NACS - NACS (Neptune Adjustable Communication Support) (code 33054). The patented NACS is an adjustable support arm for the Ocean Reef GSM GDivers Communications System and other Ocean Reef underwater communication units. It can be installed on the left side of the mask and prevents the communication unit from hanging on the mask strap. By relieving the weight of the communication unit, the NACS also allows the mask strap to slide easily through the buckle; thus, the strap can stay loose while the mask is donned, and the communicator stays out of the way. (NACS NOT INCLUDED with the M-101A)
