California`s Scubapro said Wednesday it was recalling 670 of its X650 second-stage regulators.

A manufacturing error could cause the main housing of some regulators, which divers place in their mouths to breathe, to change shape over time, which could cause the cover and diaphragm to become dislodged, Scubapro said. If this occurs, airflow will be interrupted and the regulators will no longer function, posing a drowning hazard to users.

There have been reports of incidents or injuries.

The recall involves some 670 X650 second-stage regulators, all of which are marked with a blue capital 'X' next to the numbers '650' in white. Affected regulators have a visible bump located on the right side of the unit between the letter 'C' and where the mouthpiece attaches to the regulator body.

Consumers should stop using the product immediately and contact Scubapro to determine if they have an affected second stage regulator. If so, they will receive a free replacement regulator. Questions may be directed to (800) 803-3948.
