Miniature Ascent Rate Alarm: MARA
NOW AVAILABLE!

MARA (Miniature Ascent Rate Alarm) is a new, patent protected, diving safety accessory that assists divers in knowing exactly how fast they are ascending to the surface. This is important to prevent decompression sickness, known as the bends, or gas embolism (burst lung syndrome).

This unique device attaches to any diving mask and gives the diver an audible indication of how fast they are going to the surface. Allowing for a non visual indication of ascent rate ensures the diver is looking to the surface to prevent collision with surface objects.

MARA also signals a safety decompression stop of 3 minutes at 15 feet of water as recommended by most dive training agencies throughout the world.

This sealed unit is designed to last for approximately 5 years or 1000 dive hours before it needs to be completely replaced.

There is nothing like MARA on the market today.
