Each Pick with Air Integration, Reviewed in Detail
The 3 picks below are reviewed in the same order as the cards above.
Shearwater Research Shearwater Perdix 2 13301
The Shearwater Perdix 2 13301 is a premium professional choice for divers who need a high-end subsurface computer with a robust depth rating and extensive gas support.
What we like: This model supports 5 Open Circuit and 5 Closed Circuit gases, allowing for complex gas switching—the process of changing breathing gases during a dive—to be planned and tracked. The 260m maximum operating depth provides a high ceiling for deep-water operations, while the 100-hour battery life with Saft LS14500 batteries offers long-term reliability.
Keep in mind: The 190-gram weight and glass lens construction make this a substantial piece of gear that may be less suitable for those seeking a lightweight, low-profile profile.
The Scubapro G2 Wrist 05.080.100 provides a high-end build and versatile display options for those seeking a reliable dive computer with a familiar interface.
What we like: Its 320x240p resolution is paired with a Full-Color TFT Dot matrix display screen that offers various layout options like “Classic” or “Graphical.” It also features a 3-button control system for simplified navigation while underwater.
Keep in mind: The 4.5 rating from 22 buyers provides context for its performance, but the polycarbonate material construction is a different build choice than metal or glass alternatives.
Garmin Descent Mk2i Titanium with Black Band
The Garmin Descent Mk2i Titanium with Black Band is a versatile watch-style dive computer that integrates air monitoring and smartwatch functionality.
What we like: This model features integrated pressure monitoring on up to 5 tanks via SubWave sonar data network, which transmits air consumption rates and remaining air time to the wrist. It also offers an 80-hour battery life in dive mode and includes pulse ox sensing for blood oxygen saturation.
Keep in mind: The 1.4-inch display is smaller than the 2.2-inch screens on the other models, which may impact visibility for some users during complex calculations.

The Specs That Decide a Watch-style Subsurface Computer with Air Integration
How Transducer Accuracy Range Affects Gas Switching Logic
Prioritize a wide accuracy range to ensure your gas switching logic—the rules for when to move between different gas mixes—remains precise as you change depths. The Shearwater Research Shearwater Perdix 2 13301 supports 5 Open Circuit and 5 Closed Circuit gases, providing the flexibility needed for complex gas blending. When comparing the scuba diving computer options we evaluated, the breadth of supported gas types was a primary differentiator for technical users.
Gas Switching Logic
Verify that the device supports your specific gas mixes by checking the programmed gas count before you dive. You can program up to 5 Open Circuit gases into the Shearwater Research Shearwater Perdix 2 13301. This allows for Nitrox Compatibility, which is the ability to safely use enriched oxygen mixes within specific depth limits. The Garmin Descent Mk2i Titanium with Black Band also handles multiple gas types through its integrated pressure monitoring.
Display Visibility in Low Light
Select a high-resolution screen with a dedicated backlight to maintain visibility during deep descents or in murky water. The Scubapro G2 Wrist features a 320x240p Full-Color TFT Dot matrix display, offering a clear interface in dark conditions. For those prioritizing a large viewing area, the Shearwater Research Shearwater Perdix 2 13301 uses a 2.2″ LCD screen with an LED backlight to ensure data remains legible.
Battery Life under Continuous Load
Ensure the battery life lasts a full day of multiple dives by checking the specific runtime in dive mode. The Shearwater Research Shearwater Perdix 2 13301 provides up to 100 hours of power with a Saft LS14500 battery. The Garmin Descent Mk2i Titanium with Black Band offers 80 hours in dive mode. These durations provide a significant buffer for back-to-back dives without needing to recharge between sessions.
Choosing Pressure Sensor Mounting Methods for Remote Transmitter Links
Choose a mounting method that suits your setup, such as a wrist-based sensor or a remote transmitter link. The Garmin Descent Mk2i Titanium with Black Band uses a SubWave sonar data network to link with a separate T1 transmitter for pressure monitoring on up to 5 tanks. This allows the watch to display remaining air time and air consumption rates without a physical hose connection. The Scubapro G2 Wrist utilizes a 3-button control system and is reverse compatible with Galileo accessories for integrated sensor setups.

What Each Job Calls For vs What These Picks State
Match the job you actually need done to the figure it calls for, then check which picks state that figure or more. Where none do, the row says so.
| What you want to do | The figure it calls for | Picks at or above it |
|---|---|---|
| monitor tank pressure from the wrist | integrated pressure monitoring | Descent Mk2i Titanium |
| see air consumption and remaining time | integrated pressure monitoring | Descent Mk2i Titanium |
| monitor multiple gas mixes | 5 open circuit gases | Perdix 2 |
These figures are the levels this category is generally held to, not manufacturer claims. A pick at or above a figure states that number; how it reaches it and the rest of your setup still decide the job, so check them against your own workload before buying.

What These Subsurface Computers Need, and What to Check on Arrival
Pre-purchase requirements for air integration
Each of these scuba diving computers requires a compatible pressure transmitter to provide real-time air data to the wrist unit. Without a matching transmitter and a pressurized tank, the integrated air features will not function.
- The Shearwater Research Shearwater Perdix 2 13301 supports 5 Open Circuit gases and 5 Closed Circuit gases, but requires a compatible transmitter to share these gas profiles.
- The Garmin Descent Mk2i Titanium with Black Band integrates pressure monitoring on up to 5 tanks via the SubWave sonar data network, which requires a Descent T1 transmitter (sold separately).
- The Scubapro G2 Wrist uses a 3-button control system and is reverse compatible with Galileo accessories for its specific air integration setup.
Verifying your order on arrival
Warranty coverage and return policies vary by seller and country, so verify these details before the return window closes.
- Confirm the display functionality of the Scubapro G2 Wrist, as its polycarbonate (PC) housing protects a 2.2in/5.6cm Full-Color TFT Dot matrix display screen that is difficult to service if cracked.
- Check the screen clarity of the Garmin Descent Mk2i Titanium with Black Band to ensure the 1.4 inch color sunlight-readable display shows clear data for your planned dive.
- Verify the glass lens on the Shearwater Research Shearwater Perdix 2 13301 is free of deep scratches, as the aluminosilicate glass protects the 320×240 resolution screen from abrasive environments.
- Ensure the device powers on and recognizes the battery, as the Perdix 2 13301 can run for 100 hours with a Saft LS14500 battery.
Perform a firmware update, which is a software process necessary for maintaining safety algorithms, the moment you power on the device for the first time.
Transmitter compatibility and air data
The air integration for these units depends on the specific sonar or wireless protocol used by the transmitter, not just the brand of the tank.
The Garmin Descent Mk2i Titanium with Black Band uses the SubWave sonar data network to provide integrated pressure monitoring on up to 5 tanks. This means it can display remaining air time and air consumption rate for any tank paired with a Descent T1 transmitter. The Shearwater Research Shearwater Perdix 2 13301 provides air integration for up to 5 Open Circuit gases, allowing a diver to monitor gas levels during a technical dive in a cave system where constant gas awareness is required.
