The Mares Mission Puck 3 Dive Computer-AS-ONE combines a compact pressure gauge, an analog compass, and the Puck computer in an ergonomically shaped chrome-plated brass housing. Designed for scuba and diving gear, it uses a simple, single-button interface with the Easy Access system to reach core functions quickly, keeping you focused on the dive ahead.

With Nitrox support from 21% to 50% and a maximum displayed depth of 150 m (492 ft), this unit provides practical depth and gas data in a small, easy-to-read package. The built-in logbook stores up to 35 hours of dive profiles with 20-second sampling intervals, and a user-replaceable CR2450 battery supports long-term use. An integrated compass, multiple lanyard attachment points, and a reliable ascent-rate indicator contribute to a straightforward and functional diving experience.
