Make the bends a thing of the past with MARA®:
Miniature Rate Ascent Alarm

MARA makes diving safer by monitoring ascent rate to help prevent decompression sickness or “the bends”.

This small diving accessory fits on any mask strap. It sounds a series of alarms to the diver if it detects they are ascending too fast. Divers can easily hear the tones even when wearing a hood.

When you can’t see or hear your dive computer MARA is always there.

MARA is ideal for a wide range of divers:

• new divers still learning to control their buoyancy
  
  
• underwater photographers with hands full who can't read their computer
  
  
• anyone who can't afford a dive computer with an audible alarm
  
  
• divers in low visibility situations or night dives where gauges are difficult to see
  
  
• divers who can't see or hear their dive computer

"After being alerted by the MARA® alarm beeps through my hood, I confirmed that my ascent was too rapid on my computer and took action accordingly. You have a new fan!"
