Recalls of Mares Computers and Tusa Regulators

If you’ve got a Nemo Air dive computer, contact your dealer now. Mares issued a recall last summer for the slow-leaking O-rings on its Nemo Air computer’s Quick Connector hose, but it turns out the replacement O-ring issued wasn’t the solution. On February 1, Mares announced another recall for the hose. “We determined the replacement o-ring was not the best fix so we designed a whole new quick disconnect system to replace it,” Mares’ national sales manager Steve Lamphear told Undercurrent. “The computer itself works fine, it’s only the Quick Connector that can leak through.” Mares’ Italian technicians redesigned the entire metal fitting at the end of the Quick Connector hose holding the o-ring; the new replacements have a groove machined around the middle of the fitting. All Nemo Air computers need this replacement, so contact a Mares dealer to get the new Quick Connector hose replacement, free of charge. If you want Mares to do the replacement, call Customer Service at 800-874-3326 and give them your computer’s serial number for shipping info.

Tusa is recalling its RS-670 regulators distributed and sold between May and September 2009 because loosening of the BLC plug on the first stage may cause a high-pressure leak. We contacted Tusa twice for more details, but no one returned our calls. If you’ve got an RS-670, check the serial number printed on the first stage. Affected units have serial numbers between 22 and 29, 31 and 103, 637 and 676, 708 and 716, and 737 and 776. Take your regulator back to the dealer, contact Tusa by e-mail at, or call 800- 482-2282 to mail it back for a BLC plug replacement, covered under warranty.
