Air Integration — What It Is and Why It Matters

Air integration is a dive computer feature that tracks your remaining tank pressure in real time, either through a direct high-pressure hose connection or a wireless transmitter mounted on the first stage of your regulator. The computer uses your breathing rate and remaining air to calculate an estimated air time remaining (ATR) at your current depth and consumption rate.

Wireless air integration has become the standard on mid-range to high-end dive computers, with brands like Shearwater, Suunto, and Garmin offering proprietary transmitter systems. The main advantage is eliminating the need to constantly check a separate SPG console, keeping all critical data on one screen.
