MARA® Miniature Ascent Rate Alarm
NOW AVAILABLE!
MARA® (Miniature Ascent Rate Alarm) is a patent-protected
diving accessory designed to make diving safer.
MARA 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 diving safety device
attaches easily to any diving mask. It gives the diver an audible indication
of how fast they are ascending to the surface.
MARA contains superior electronics and a high end industrial pressure sensor.
It detects changes in water pressure and analyzes it against time and electronic
dive tables. If MARA detects the diver ascending at a rate faster than 30 feet
or 10 meters/minute, it sends an alarm warning to slow down. It even provides
a Safety Stop at 15 feet or 10 meters.
MARA comes with a 1 year warranty. This sealed unit is designed
to last for approximately 5 years or 1000 dive hours before it needs to be
completely replaced. MARA is battery operated and only activated
under water. The battery is non-replaceable and customers may return their MARA to
the manufacturer for recycling.
When you can't see or hear your dive computer, MARA is always
there to help you ascend safely.

"I have been using the MARA system while teaching and diving recreationally
for the past 6 months. While it cannot replace my dive computer, the MARA
system provides an audible ascent alarm that I have come to rely upon whether
doing multiple ascents with students or coming up after an extended pleasure
dive. My dive computer only warns me when I exceed the optimal ascent rate
of 30 feet per minute, and the alarm is barely audible. As an instructor,
I appreciate the safty and simplicity of being able to maintain ascent rate
standards without having to take my eyes off my student. My MARA tells me
exactl how fast I am ascending whether 30, 40, 50, or 60 feet per minute,
all while I am in full control of my student."
