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. MARA even provides a safety decompression stop of 3 minutes at 15 feet or 4 meters.
