Ocean Reef Introduces the GSM Mercury Unit

Ocean Reef is proud to introduce GSM Mercury, the most advanced ultrasonic wireless underwater communication unit OCEAN REEF has ever made.

This unit is blending four different OCEAN REEF units into one: the extended range of the Gpower, the like-stereo sound of the GSM SL, the clearness and double channel option of the DC and the battery life of the Gdivers.

It’s foldable inside the mask and easy to operate with a brand new rechargeable, changeable battery and new design with an autonomy of approximately 30 hours.

GSM Mercury is digital, double channel unit and depending on the surrounding environment conditions, it reaches a range of 800ft /250 meters.


DAT (Digital Activation Transmission)

This automatic activation system is an exciting innovation in underwater communication exclusively from OCEAN REEF. The DAT™ system allows the option of transmitting in a hands-free mode rather than manual mode. A series of impulses are sent out, automatically keeping the unit in transmit mode for 30 seconds. After the initial 30 seconds of transmit mode, the unit will return to receive mode for 20 seconds accompanied by a series of impulses in a different tone from the first. DAT™ is useful when it is necessary to have both hands free while transmitting, making diving more comfortable and safer. Another benefit of the DAT™ system comes in the case of an emergency; by activating the DAT™ a series of impulses will emit every 30-20-30 seconds, which can be received at a great distance by search and rescue workers and other divers. DAT system is an Ocean Reef Exclusive.

Two is always better than one: Mercury features two speakers to have louder and clearer communications and two separate channels to guarantee privacy for separate conversations, i.e. teams, students/instructor.
