What is an Integrated Dive Mask (IDM)?

Full-face diving masks have long been used by commercial divers but have always been too complicated and expensive for recreational divers. Ocean Reef has created a comfortable, easy to use and affordable integrated dive mask with their Neptune Space line.

More than just a full-face mask, the Ocean Reef Integrated Dive Mask not only combines a regulator into a mask but has a series of optional integrated solutions such as a frame for corrective lenses, surface air valve, underwater communication unit, visor lights, dive data recorder and more.
