MARA: Miniature Ascent Rate Alarm

The Miniature Ascent Rate Alarm - MARA, was designed to make the sport of diving safer. It has been found to be exceptional for the training of new and seasoned divers alike to ensure they ascend at a safe rate. As a well trained diver, you know a safe ascent rate is one of the most important aspects of diving.

MARA ensures the diver is aware of how fast they are ascending to the surface with no effort from the diver.
