Air integration is a vital feature for monitoring your air supply during a dive. To ensure you have the most accurate information, consider using a dive computer with air integration from this curated list.

Why Air Integration Matters

Understanding your remaining air supply is critical for safe diving. Air integration provides a way for your dive computer to monitor tank pressure in real time, rather than relying on the diver to check their submersible pressure gauge.

This enables more accurate tracking of air consumption rates and smarter planning regarding turn pressures and ascent rates. For technical divers carrying multiple tanks, air integration simplifies monitoring gas supplies across different mixes.

Overall, air integration gives divers enhanced situational awareness and safety.

How Air-Integrated Dive Computers Work

Air-integrated dive computers connect to a diver’s first-stage regulator via a high-pressure hose. This allows a pressure sensor in the dive computer to monitor tank pressure and transmit data via a wireless connection.

The diver can view the pressure of all connected tanks on the dive computer display.

Advanced air integration dive computers use this pressure data in conjunction with depth, time, and breathing rates to estimate remaining bottom time and make ascent rate recommendations.

Key Features of Air-Integrated Dive Computers

Air-integrated dive computers also provide a number of advanced functions and capabilities not possible with standard non-air-integrated models.

Here are some of the most important features:

Precise Tank Pressure Readings

  • The pressure sensor integrated into the high-pressure hose provides real-time monitoring of tank pressure rather than relying on periodic checks by the diver.
  • This enables the computer to give warnings when tank pressure reaches critical thresholds, such as reaching turn pressure and reserve pressure.
  • The continuous stream of pressure data is accurate to within a few psi, versus periodic checks that may miss pressure swings.

Wireless Transmission

  • The pressure data is transmitted wirelessly from the high-pressure sensor to the dive computer display.
  • This gives flexibility in positioning equipment rather than needing to mount the dive computer on the regulator.
  • Wireless transmission eliminates hoses going to the dive computer. Most systems have a range of 6 feet or more.

Air Time Remaining Estimates

  • The computer uses real-time pressure data along with the diver’s breathing rate to estimate the remaining bottom time.
  • As the breathing rate increases due to exertion, the computer dynamically updates the estimates, unlike manual systems.
  • This allows the diver to monitor no-decompression limits based on the air supply.
  • Warnings can be given when reaching the minimum air reserves needed for ascent.

Ascent Rate Monitoring

  • Knowing the remaining air supply, the computer can recommend safe ascent rates.
  • If air is limited, the computer may suggest faster ascents to the first stop compared to dives with abundant air.
  • This balances decompression needs and air requirements.

Multiple Tank Monitoring

  • For technical divers, air integration allows easy monitoring of multiple tanks.
  • The pressure levels of all tanks are displayed in a consolidated view, rather than needing to check SPGs.
  • If tanks have different gas mixes, the computer keeps track of which supply is in use during different phases.

Pros and Cons of Non-Air-Integrated Dive Computers

Non-air-integrated dive computers rely solely on the diver manually inputting changes in tank pressure. The diver must periodically check their submersible pressure gauge (SPG) and input this data into the dive computer.


  • Lower cost than air-integrated models
  • Simpler setup without hoses
  • Universal compatibility with any regulator system


  • Tank pressure must be checked manually
  • Does not automatically factor air supply into dive planning
  • Higher risk of running out of air if not monitoring SPG
Air Integration Improves Dive Planning

How Air Integration Improves Dive Planning

One of the biggest advantages of air integration is that it allows dive computers to incorporate real-time remaining air supply information into their dive planning algorithms and warnings.

This provides major improvements in situational awareness and safety.

Precise Turn Pressure Warnings

  • The computer can give turn pressure alerts based on the real-time tank pressure data rather than relying on the diver’s periodic checks of their SPG.
  • This reduces the risk of unintentionally descending below planned depths due to not checking pressure as frequently.
  • The warnings can factor in the remaining no-decompression time and ascent rate to optimize turn pressures.

Dynamic Time Remaining Countdowns

  • The computer displays the estimated bottom time remaining based on real-time breathing rate and tank pressure data.
  • As the exertion level changes, the computer dynamically recalculates the time remaining, providing a countdown that is more accurate than manual systems.
  • This allows the diver to more precisely monitor no-decompression limits based on up-to-date situational data.

Optimized Decompression Ascent Rates

  • Knowing the precise remaining air supply in real-time, the computer can recommend ascent rates that balance decompression needs and air requirements.
  • This may involve slightly faster ascents to the first stop compared to dives with more air supply.
  • The result is decompression schedules customized based on your tank status rather than generic ascent rates.

Emergency Air Supply Management

  • If air supply becomes critically low for any reason, the computer can provide emergency ascent rates and stop depth recommendations to get the diver to the surface safely with minimal air.
  • For situations like a bad SPG reading or regulator failure, air integration data improves decision-making.
  • It allows computers to adapt emergency recommendations based on real-time pressure trends.

Are Air-Integrated Dive Computers Necessary?

While air integration clearly provides significant advantages, non-air-integrated dive computers can still be completely adequate for some divers’ needs if proper protocols are followed.

Here is a closer look at when air integration is most beneficial versus situations where it may be less essential.

Recreational No-Decompression Diving

  • For single-tank, no-decompression recreational dives within no-decompression limits, periodically checking SPG and manually inputting pressure changes into the computer is generally reasonable.
  • The need for real-time air data is reduced when staying well within limits and maintaining reserves for ascent.
  • Following the good practice of checking SPG every few minutes can sufficiently supplement a non-air-integrated computer.

Technical, Multi-Gas Diving

  • For technical divers carrying multiple tanks, making decompression stops, and managing multiple gas mixes, air integration is highly recommended.
  • The complexity of this diving requires constant monitoring of supply across different tanks, and real-time data enables this level of awareness.
  • Air integration greatly reduces task loading for these divers by consolidating pressure data.

Infrequent or Inexperienced Divers

  • Divers who only go out a few times a year may find air integration useful but have difficulty justifying the cost for the limited number of dives.
  • Inexperienced divers who struggle with situational awareness can benefit from air integration but likely need to improve their fundamentals first.
  • Air integration provides significant advantages but should not replace developing core dive skills.

Addressing Technology Complacency Concerns

  • Over-reliance on technology can lead to dangerous complacency, where divers forget to perform basic self-checks.
  • Even with air-integrated computers, divers should maintain the habit of periodically checking their SPG as a redundant safety protocol.
  • Air integration provides more data but should not be an excuse for losing dive awareness.
