RECALLS: Mares Nemo Dive Computer and TUSA RS-670 Regulators

CPSC Date: 4/14/2010

Name of Product: Mares Nemo Air Dive Computers

Units: About 600 in the United States, 140 in Canada and 15 in Puerto Rico

Distributor: Mares USA, of Boca Raton, Fla.

Hazard: An O-ring in the high pressure air connector can fail and leak air, causing a continuous but slow loss of breathing gas, which could require a diver to surface quickly, posing a drowning hazard to divers.

Incidents/Injuries: None reported.

Description: This recall involves the Mares Nemo Air Dive Computer, Nemo Air Dive Computer with Compass, Mares High Pressure Hose with Quick Connector for Nemo Air, and Quick Connector Assembly for Nemo Air. These computers have a digital screen which allows scuba divers to measure the time and depth of a dive and process other information to help divers determine safe dive times and ascent rates.

Sold by: Specialty dive shops nationwide from July 2008 through July 2009 for between $800 and $900 (U.S.) and between $880 and $990 (Canadian).

Manufactured in: Italy

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.
