Undersea Systems International Inc., dba Ocean Technology Systems, of Santa Ana, CA. is recalling 1,700 Guardian full-face diving masks in the United States and 80 in Canada in cooperation with the U.S. Consumer Safety Commission and Health Canada.


The purge assembly on the diving mask can disengage from the regulator, resulting in loss of air to the diver. This poses a drowning hazard to the consumer. The firm has received one report of a disengaged assembly. No injuries have been reported.


This recall involves Guardian full-face diving masks with serial numbers 9051284 through 100070954. The serial number is printed on the main regulator body. The diving masks were sold in black with blue accent colors. The Ocean Technology Systems' logo is affixed to the front of the mask.


The masks were manufactured in Taiwan and sold by diving equipment retailers and via direct sales nationwide from September 2010 through November 2010 for about $800.
