An air integrated dive computer combines your dive computer and submersible pressure gauge into a single unit, using a wireless transmitter on your regulator to display real-time tank pressure and Gas Time Remaining (GTR) on your wrist or console. Unlike a traditional dive computer, which calculates decompression from depth and time alone, an air integrated system captures your actual gas consumption — the only real-time proxy for your in-water exertion and physiological nitrogen loading.

Why Gas Consumption Is the Missing Safety Variable
Traditional dive computers calculate decompression using just two inputs: time and depth. They treat every diver identically — the same weight, fitness, and exertion level — regardless of what is actually happening underwater.
The missing variable is individual effort. When you work harder underwater, you breathe faster. A higher breathing rate means more nitrogen delivered to your tissues per minute — beyond what any time-and-depth model can predict. The best real-time proxy for that effort is gas consumption: your Surface Air Consumption (SAC) rate.
Air integrated computers capture SAC rate on every dive. This data now underpins emerging research linking gas consumption to post-dive inert gas bubble grades — a measurable indicator of DCS risk. The computer logging your breathing rate today is building the dataset that personalised decompression algorithms will run on tomorrow.

Wireless transmitter systems are not interchangeable between manufacturers. Each brand uses a proprietary protocol.
| Brand | Transmitter | Max Units |
|---|---|---|
| Shearwater | SWIFT TX | 2 |
| Garmin | Descent T1 | 5 |
| Suunto | Wireless Tank POD | 1 |
| Scubapro | G2 Transmitter | 2 |
| Mares | Transmitter T | 1 |
⚠ Transmitter protocols are brand-specific. A Suunto transmitter will not pair with a Garmin computer. Always verify compatibility with your specific model before purchase.
Frequently Asked Questions
An air integrated dive computer combines your dive computer and submersible pressure gauge (SPG) into a single system. A wireless transmitter screws into the high-pressure (HP) port on your regulator first stage, reads tank pressure in real time, and sends that data to your wrist or console display. The computer then combines pressure, depth, and breathing rate to calculate Gas Time Remaining (GTR) — a constantly updating estimate of dive time based on your actual air consumption, not just decompression limits.
The best overall air integrated dive computer in 2026 is the Shearwater Teric for most divers — combining technical-grade Bühlmann ZHL-16C algorithm, AMOLED display, and dual SWIFT transmitter support. For technical divers, the Shearwater Perdix AI offers superior glove-readability and sidemount capability at a lower price. For travelling divers, the Garmin Descent Mk3i provides up to 5 simultaneous transmitters and daily GPS smartwatch functionality.
No. The Shearwater Peregrine is not air integrated. It does not support the SWIFT wireless transmitter. For air integration in the Shearwater range, you need the Teric, Perdix AI, or Perdix 2.
