Take control of your dive with this US Divers Matrix Masters Dive Computer. Turn on this computer and after a self diagnostic check the unit enters Surface mode which displays the depth, time, wait to fly timer, and pre dive planning sequence. When the Matrix Master goes deeper than five feet, it switches from Surface Mode to No-Decompression Dive Mode. In No-Decompression Dive Mode the computer displays the current depth, no-decompression time, maximum depth, bottom time, compartment loading bar graph and ascent rate indicator. This unit also has a decompression dive mode and a dive log mode. These computers are AS IS but were tested and powered on with new batteries. Batteries not included
