MARES Dive Computer Recalled

As reported by the Associated Press about 600 Mares Nemo Air Dive Computers manufactured in Italy and distributed by Mares USA of Boca Raton have been recalled because a piece in the high pressure air connector can fail and leak air.

The failure with the O-ring could cause a slow loss of breathing gas, which could require the diver to surface quickly, posing a drowning hazard. The recall also involves 140 dive computers in Canada and another 15 in Puerto Rico. No incidents have been reported. Specialty dive shops nationwide sold the items from July 2008 through July 2009.

Mares Computer O-ring

Remedy: Consumers should immediately stop using the recalled dive computer and connectors, and return the products to their authorized Mares dive shop for a free replacement O-ring connector assembly. The O-rings in some units may already have been replaced, but this recall requires replacing the metal quick connector fitting at the end of the high pressure air hose that holds the O-ring. Replacement connector assemblies have a groove machined around the middle of the fitting, but recalled units do not. All consumers should take their Nemo Air dive computers to a Mares dive shop to confirm whether this connector fitting has been replaced.

Consumer Contact: For questions, contact Mares at (800) 874-3236 between 9 a.m. and 5 p.m. ET, visit the firm’s web site at (this is a pdf file that can be downloaded) or e-mail the firm at
