The Mares Quad Dive Computer is a wrist-worn scuba dive computer built around a large, three-line “Jumbo Size” segment display and a mirrored four-button layout, with a maximum displayed depth of 150 m / 492 ft and a user-replaceable CR2450 battery rated for 200 to 300 dives.
Who it is for
The Quad suits recreational and nitrox divers who want a straightforward wrist computer with an easy-to-read screen and simple button operation, both on land and underwater. Its gas switching and multi-mixing capability make it a fit for divers who use enriched air or switch gases during a dive, while the Deco Dive Planner and Runaway Deco Alarm help divers plan surface intervals and stay aware of mandatory deco stage increases.

Compatibility and sizing
The Quad is available in four color combinations: Black/Yellow, Black/Blue, Black/Black, and Black/White. The original wrist strap can be swapped for bungees for divers who prefer that fit, and the computer supports Mares’ BLUELINK bluetooth system for recording and sharing dive data with a smartphone. Each unit ships with a compact instruction manual printed in 20 languages, inserted into the original packaging.
