What the authority reported
This recall involves Poseidon M28A Dive Computers used for diving. They calculate continuously and present needed data for divers. The M28A works stand alone or in combination with the Poseidon SE7EN Rebreather. Only dive computers with a serial number starting with "M28A-" are included in this recall. The serial number and two metallic wet-switches are located on the back side of the recalled dive computers. Hazards: The recalled Poseidon M28A Dive Computers can stop working due to intake of water causing a malfunctioning depth sensor resulting in a loss of dive data for the diver, posing an injury hazard.
