Integrated Diver Display Mask

From Wikipedia, the free encyclopedia

The Integrated Diver Display Mask (IDDM) is a diving mask which contains a small basic heads-up display that lets divers monitor depth, bottom time, tank pressures, and related information while leaving their hands free for other tasks.

Oceanic / Aeris supply it. It was developed by Oceanic and the U.S.Navy. The United States military has adopted it.
