ScubaCom O2D is the result of cooperation between experienced rescue divers and electronics specialists with many years of experience in the communications sector.


ScubaCom O2D is a diver communication unit for excellent voice communication between up to two divers and a signal person above water. The connection is established with a diver communication rope, which also serves as a safety and signal rope, an underwater headset for the diver and an above-water headset for the signal person.
