Tech Specs

Oceanic Algorithm Expertise
At the heart of the O.i Wrist is the proven Bühlmann ZHL-16C decompression algorithm with Gradient Factors, delivering precise dive calculations and customizable conservatism levels for divers of all experience levels. Whether diving air, enriched air Nitrox, or managing multiple gas mixes, O.i continuously adapts to provide reliable guidance throughout every phase of your dive.

Multi-Gas Capability
Built for more advanced dive profiles, O.i supports up to three (3) gas mixes. If a more suitable gas becomes available during the dive, O.i notifies you with visual and haptic alerts.

Nitrox Ready
O2 22-100% for enriched air and decompression dives, with independent PPO₂ management and MOD awareness for each configured gas.

Wireless Air Integration
Compatible with the optional Oceanic Wireless Transmitter. Provides critical dive information including cylinder pressure, real-time Air Consumption, and Gas Time Remaining (GTR), O.i supports up to three transmitters simultaneously.

Scuba and Gauge Operating Modes
Choose full-featured Scuba mode for real-time decompression tracking and essential dive data, or Gauge mode for depth, time, and temperature monitoring when using O.i as a bottom timer.

Depth Rating
Depth-rated to 328 ft (100 m) for recreational and advanced scuba diving.

Connectivity
GPS surface position records your entry and exit locations for dive logging, while automatic time synchronization keeps the computer’s date and time accurate when connected. Stay connected after the dive with built-in wireless technology and seamless integration with the Oceanic+ app on iPhone and Oceanic WebApp on Mac, Windows, and Android. Divers can conveniently manage settings, install software updates, sync dive data, and review their dive history across compatible devices.

Integrated

O.i brings your dive equipment and digital experience together. Wireless air integration connects up to three transmitters, while GPS, wireless technology, and the Oceanic+ app let you log surface locations, manage settings, and sync dive data seamlessly—all powered by wireless induction charging that keeps O.i ready for your next dive or adventure.
