The Mares QUAD 2 Dive Computer is a dependable choice for scuba and diving gear, delivering precise decompression calculations and versatile gas support for a wide range of underwater missions. It handles Air, Nitrox (21–99%), and Trimix (Hypoxic, Normoxic), with gas switching to adapt to varying dive profiles and conditions.

Its Bühlmann ZH-L16C algorithm with customizable Gradient Factors provides tailored decompression planning for both recreational and technical diving. The device features a crystal-clear segmented display, a glove-friendly four-button interface, and a decompression planner with a Surface Interval function. A logbook stores up to 100 hours of dive profiles at a 5-second sampling rate, while Bluetooth connectivity enables syncing with the Mares app for firmware updates and dive-log sharing. Automatic altitude adaptation keeps readings accurate during altitude diving, and the user-replaceable CR2450 battery offers up to 100 hours of dive time for reliable performance across trips.
