The Aquacom MK2-DCI is a compact, self-contained two- or one-diver air intercom. It will provide one or two divers, using a Full-Face Mask and Ear/Microphone Assembly, with clear communications either in the 2- or 4-wire mode. However, up to 6 divers can be stacked and all be on line together (4-wire mode).

The 20 watts of power ensures clean, crisp communications over long lengths of communications rope. State-of-the-art circuitry allows intelligibility that is second to none. Our unique battery protection microprocessor will protect your batteries from being damaged due to extreme low voltage conditions.
