Oceanic O.i Wrist Dive Computer

The Oceanic O.i is a wrist-mounted dive computer built around a 2.4-inch full-color TFT display and a rotating NavDial controller. Turning and pressing the dial moves through the screens and menus, and haptic feedback confirms each input, so the interface stays workable in gloves and in low visibility.

Decompression is calculated with the Bühlmann ZHL-16C algorithm using Gradient Factors, and the conservatism level is adjustable to suit the profile and the diver. The computer runs in Scuba and Gauge modes, accepts Nitrox mixes from 22 to 100 percent oxygen, and tracks PPO2 and MOD independently for each of up to three configured gases. A built-in planner previews no-decompression limits for a given depth and bottom time before the dive.

Wireless air integration pairs the computer with up to three transmitters, sold separately, for real-time tank pressure and gas-time-remaining. Integrated GPS records entry and exit points and sets the clock automatically, and a 2.4 GHz wireless link connects the O.i to the Oceanic+ app and WebApp for dive log sync, device settings, firmware updates and language packs.

Secondary screens including the digital compass with timer and the customizable Digital Dive Slate can be switched on or off individually. Screen orientation and NavDial position reverse for left- or right-wrist wear. Altitude is detected automatically from GPS and barometric data and folded into the decompression calculation, and no-fly time is counted down from the actual dive profile.

The display sits behind tempered mineral glass and the housing is depth rated to 328 feet (100 meters). The sealed rechargeable battery charges by wireless induction, reaching roughly 80 percent in about 30 minutes.
