Tabata USA is recalling about 250 TUSA RS-670 SCUBA regulators. The first stage balance chamber plug can loosen from the scuba regulator causing a high-pressure leak and creating unstable pressure. This poses a drowning hazard to divers.

This recall involves R-600 first stage scuba regulators with the following serial numbers: UR600022 through UR600029, UR600031 through UR600103, UR6000637 through UR6000676, UR600708 through UR600716, UR600737 through UR600776. The serial number and TUSA logo are printed on the regulators.
The regulators were sold by authorized TUSA distributors and diving and equipment stores nationwide from May 2009 through September 2009 for about $450. They were made in Japan.
Consumers should immediately stop using the scuba regulators and return the product to TUSA or an authorized dealer for a free inspection and replacement.
For additional information, contact Tabata USA at (800) 482-2282 between 8:30 a.m. and 5 p.m. PT Monday through Friday, or visit the firms Web site at www.tusa.com.
The recall is being conducted in cooperation with the U.S. Consumer Product Safety Commission (CPSC).
