US Divers Matrix Module

The MATRIX is a wrist- or console-mounted dive computer that can track multi-level air dives but is not Nitrox-capable. It is no longer in production.

What Does It Need?

Normal service on this model involves periodic battery replacement. Indications that it is time for battery replacement include:

• A “low battery” indicator appears, as covered in the Owners Manual.
• The computer was functioning properly when last used; however, after a period of inactivity, it simply will not turn on.
• The computer will turn on but shuts down shortly afterword, or displays erroneous information.

The cost for battery replacement is US$45, plus return shipping costs.

Be aware that any problems a Matrix may have that cannot be fixed by replacing the battery are not repairable. In this case, it’s time for a new computer.
