Air integration is handled through the separately sold Descent T2 transceiver, while the SubWave sonar system adds communication and awareness features that go beyond basic pressure monitoring. A diver can exchange preset messages with nearby partners and, when paired with the transceiver, monitor pressures, distances, and depths for as many as eight divers within the stated network range. The included DiveView mapping features also help with surface planning and site research.
The main trade-off is accessory dependence. A buyer who wants the advertised tank-pressure and team-tracking functions must account for the separate T2 transceiver, and the large touchscreen may not feel as natural to everyone. Even so, the X50i offers a rare combination of premium hardware, detailed dive data, mapping, team communication, an onboard log, and Garmin app connectivity in one package.
This is the strongest choice for a diver who wants more than a wrist gauge and values screen space, rugged construction, and ecosystem features. It is particularly suitable for travel, expedition planning, and buddy-diving situations where detailed information and communication matter. Choose it after confirming that its large format and optional accessory ecosystem match your preferences.
A Dive Computer Built for Detailed Information
The 3-inch touchscreen makes projected ascent profiles, depth charts, and other critical information easier to inspect at a glance. That extra room benefits divers who regularly review many fields or use the computer for detailed post-dive analysis.
Team Awareness Beyond Tank Pressure
SubWave supports preset diver-to-diver messaging and can share selected tank, distance, and depth information among nearby divers. That turns the X50i into a more connected safety tool when paired with the appropriate hardware.

The wrist computer can connect with up to five transmitters and show real-time tank pressure and saturation information in color-coded form. It supports air, nitrox, and trimix modes, while the customizable Bühlmann ZH-L16C algorithm lets divers adjust gradient factors for a more personal deco profile. A full-tilt digital compass, stopwatch, Bluetooth connectivity, and Mares app support broaden its use beyond pressure monitoring.
The principal consideration is that the supplied product information does not identify the transmitters as part of the package. Buyers should therefore treat this as a computer capable of hoseless tank integration rather than assume that a complete multi-tank kit is included. Its smaller display also provides less room for detailed graphs than the 3-inch Garmin or full-color screens of the SCUBAPRO G2.
The Quad Ci is a strong recommendation for divers who want five-tank support, configurable decompression settings, and app connectivity without moving to a watch-style multisport device. It also suits those who prefer a conventional wrist computer with physical controls and a readable color display. Verify the transmitter bundle and the required accessories before ordering.
Personalized Deco With Flexible Gas Support
Adjustable gradient factors allow the Bühlmann ZH-L16C model to be configured more closely to a diver's risk preferences and planning habits. Support for air, nitrox, and trimix makes it useful across a wider range of recreational and technical dives.
Multi-Tank Monitoring in a Conventional Design
The ability to connect as many as five transmitters provides more flexibility than many single-tank setups. Color-coded pressure and saturation information helps keep the essentials visible without turning the wrist unit into a full-size console.

We may earn a commission when you buy through this link, at no additional cost to you.
Positioning supports GPS L1C/A, Galileo E1B/C, and BeiDou B1l, giving the device access to multiple GNSS constellations. The wrist unit has a 2.2-inch full-color QVGA LCD, while the transmitter is rated to 200 meters and can offer up to 100 dive hours or two years of storage with its replaceable CR2 battery. The computer itself carries a 120-meter depth rating, and its ballistic nylon case, silicone strap, and stainless clasp support regular use.
There is an important distinction between the two components: the GPS transmitter is included, but the pressure transmitters that provide air integration are optional. The package also separates the computer's stated depth rating from the deeper rating of its GPS transmitter. Buyers should understand this division and verify accessory compatibility before planning to use more than one cylinder.
This Peregrine TX is ideal for divers who want integrated surface GPS without giving up wireless tank pressure support. It is especially relevant for travel, remote shore entries, and divers who want dependable location data alongside decompression information. It earns a place among the top picks because it combines air integration, navigation, and long transmitter endurance in a well-equipped package.
Surface Navigation That Starts Before the Dive
The included GPS transmitter adds multi-constellation location tracking for planning entries and identifying remote sites. Because positioning happens at the surface rather than underwater, it complements the wrist unit's dive data without replacing standard compass navigation.
Flexible Tank Monitoring With Long Battery Life
Up to four optional transmitters can be connected for multi-cylinder monitoring. The GPS transmitter's replaceable battery and stated endurance are designed for repeated use, while the wrist computer retains a focused full-color display for critical dive information.

The SCUBAPRO G2 is the broadest technical-focused package in this guide, combining a wrist computer and transmitter bundle with a 5.0 rating. Hoseless air integration reports cylinder pressure, calculates true remaining bottom time, and incorporates air consumption into decompression calculations. That combination makes it especially persuasive for technical and multi-cylinder divers who want gas information to influence their calculations rather than merely appear as a number.
Pros
- Exceptional 5.0 rating
- Transmitter bundle included
- True remaining bottom time
- Extensive display customization
- Five major dive modes
Cons
- Large feature set requires setup
- Transmitter limit varies by activation
We may earn a commission when you buy through this link, at no additional cost to you.
The 2.2-inch full-color TFT screen has a resolution of 320 by 240 pixels and offers Light, Classic, Full, and Graphical layouts. Its Predictive Multi-Gas ZHL-16 ADT MB algorithm supports up to eight nitrox or trimix mixes, and the dive modes cover scuba, freediving, gauge, CCR, and sidemount. A full-tilt compass with bearing memory, 120-meter operating limit, and generous 485MB of memory further extend its capabilities.
The listed transmitter support reaches eleven when all features are activated, but that headline should not be treated as a guarantee that every useful function remains available simultaneously. The number of modes, algorithms, and customizable options also gives the G2 a steeper setup curve. Divers choosing it for a basic recreational dive may find that they never use many advertised features.
The G2 is the most logical recommendation for a serious diver who wants a complete air-integrated system with advanced gas handling, extensive logs, and strong rating. It is particularly well suited to technical, sidemount, CCR, and multi-gas diving. For a new diver, the bundle's depth may exceed immediate needs, but it offers substantial room to grow.
Gas Awareness That Influences Dive Planning
True remaining bottom time uses workload from breathing to provide a more informative view of usable gas. Feeding air consumption into decompression calculations makes this system particularly valuable when a missed gas switch or unexpected consumption could change the plan.
A Large Dive Log With Flexible Layouts
The G2 can store 1,000 hours of dive profiles, along with tables and tissue-loading status. Multiple screen configurations let divers balance detail and readability, while USB and Bluetooth Low Energy support provide convenient transfer to phones, computers, and LogTRAK.

Its 2.2-inch LCD offers an easy-to-read display, while the tilt-compensated digital compass provides headings for navigation. The stated battery endurance reaches 30 hours of diving on a wireless rechargeable battery, and Bluetooth connectivity links the device to Shearwater Cloud for dive tracking. These features make it easy to keep the computer as the central information source both during and after a dive.
The Swift transmitter is described as an option rather than an included item, so the complete cost and setup depend on the selected package. Unlike the separately listed GPS-enabled Peregrine TX configuration, this listing does not identify a GPS transmitter as part of the package. A buyer comparing the two should focus on whether surface navigation or wireless charging and longer stated dive battery life matters more.
The Peregrine TX is a balanced recommendation for divers who want a clear color screen, reliable wireless pressure data, and a compass without paying for a watch-style sports device. It is particularly useful for multi-dive trips where convenient recharging and cloud-based log management reduce friction. Confirm the presence of a Swift transmitter before placing the order.
Gas Time That Feels Practical Underwater
The optional Swift transmitter supplies real-time pressure data, which the computer converts into gas-time estimates. This gives divers a continuously updated view of consumption without relying on a separate analog gauge.
Navigation and Logging in One Wrist Unit
The tilt-compensated compass offers a straightforward heading reference, while Bluetooth and Shearwater Cloud support move the dive record beyond the wrist. The wireless rechargeable battery is stated to last up to 30 hours underwater.

Wireless air integration monitors tank pressure and provides true remaining bottom time based on the workload created by breathing. The computer offers two algorithm choices: Predictive Multi-Gas Bühlmann ZH-L16 ADT MB PMG or ZH-L16+GF with gradient factors. The package also includes a case and silicone arm strap, and Bluetooth connectivity is incorporated into the product platform.
The monochrome screen is the clearest limitation for anyone who values graphical color cues or a large color canvas. The stated 4.3 rating is also lower than those of the leading models, so divers who place the greatest weight on buyer feedback may want to consider those alternatives. Within the air-integrated category, however, the Luna's simple layout remains an advantage.
The Luna 2.0 is best for a diver who wants pressure and remaining-time information without a complicated interface. It is well suited to routine recreational scuba and travel where reliability, legibility, and straightforward operation matter more than smartwatch features or elaborate team communication. Check the package for the required tank transmitter and confirm the intended algorithm before buying.
High-Contrast Readability in Difficult Conditions
Large characters, a wide screen, and an LED backlight improve legibility in low light and choppy surface conditions. The absence of color may be a drawback for some users, but it also keeps the interface visually direct.
Simple Controls for Everyday Diving
Only two buttons are required for menus and control. That restrained design lowers the learning curve and can reduce accidental changes when a diver needs to find a critical field quickly.

Air integration requires the separately sold Descent T1 transmitter. Through the SubWave sonar network, the Mk2i can monitor pressure on as many as five tanks and show remaining air time, consumption rate, and related information for nearby divers within the stated 10-meter range. It also includes six dive modes, multisport training tools, multi-GNSS support, ABC sensors, an underwater compass, wrist heart-rate estimates, and Pulse Ox.
The broad smartwatch feature set can be overkill for someone whose only goal is a simple pressure-reading dive instrument. GPS tracking does not work underwater, so the watch's surface navigation abilities do not replace an underwater compass. The transmitter is also not included, which must be considered when comparing complete packages.
The Mk2i is the best choice for an active diver who wants one watch for diving, training, travel, and everyday use. It is a particularly strong fit for divers who value long stated dive battery life, familiar Garmin features, and multisport data beyond decompression. Buyers focused only on technical gas management may prefer the more specialized computers in this guide.
One Watch for Scuba and Training
Built-in sports apps, advanced training features, music support, smart notifications, and contactless payment extend the Mk2i well beyond diving. This makes it easier to maintain one device for daily use instead of switching between a dive watch and a sports watch.
Reliable Dive Runtime With Optional Tank Tracking
The stated 80-hour dive-mode runtime provides ample room for multi-day diving. Adding the optional T1 transmitter enables five-tank monitoring, consumption information, and shared awareness over the SubWave network.

We may earn a commission when you buy through this link, at no additional cost to you.
The display is stated to be four times higher in resolution than the preceding design and offers 14 color options that can produce thousands of combinations. A new Big layout switches between standard and giant fonts, while programmable quick-change settings make frequently used controls easier to access. Bluetooth is described as six times faster for dive-log downloads and firmware updates, with additional data-security features.
The important limitation is that the supplied information does not explicitly confirm wireless tank-pressure integration. Even though the Perdix 3 belongs to a product family associated with optional tank transmitters, a buyer should verify current compatibility instead of assuming it. The absence of a customer rating also means there is no listed consensus to help assess long-term reliability or ease of use.
The Perdix 3 is most appropriate for a diver who prioritizes an exceptionally visible and customizable screen and wants a modern interface. It may be a strong platform for air integration if the manufacturer confirms compatible transmitters, but that confirmation should be the first step for anyone buying specifically for wireless pressure data. Its display-focused strengths make it worth close consideration.
A Display Designed for Constant Reading
The 2.4-inch AMOLED panel offers a larger, brighter canvas than earlier compact models. The Big layout adds oversized type for divers who prioritize immediate recognition over dense information.
Personalization That Improves Workflow
Fourteen color choices and programmable quick-change settings let users shape the interface for different environments. Faster Bluetooth transfers also reduce friction when moving logs to a phone or applying firmware updates.

Gas handling is versatile, with support for five open-circuit and five closed-circuit gases. The onboard log stores approximately 1,000 hours of dive records, giving divers room to preserve detailed histories and review them later. Battery choice is unusually flexible: stated endurance reaches 100 hours with a Saft LS14500, 60 hours with a 1.5-volt lithium battery, or 40 hours with standard AA alkaline batteries.
Although this is an established Shearwater platform, the supplied listing does not explicitly mention wireless tank-pressure transmitters. Air integration should therefore be confirmed with the manufacturer or seller before purchase. The conventional LCD also lacks the ultra-bright AMOLED qualities of the Perdix 3, even though it remains highly usable in the conditions for which its backlight is designed.
The Perdix 2 Ti is best for divers who value proven customer feedback, deep-diving capability, extensive gas support, and long battery options. It is less obviously suited to buyers whose main requirement is a confirmed, ready-to-use air-integration bundle. Confirm transmitter compatibility, but for a deep and demanding dive computer, its specifications remain compelling.
Built for Demanding Depth Ranges
The 260-meter rating provides a substantial stated operating depth for technical and deep dives. A tough aluminosilicate lens complements the durable design, while the readable 2.2-inch display keeps essential data accessible.
Battery Choice for Long Trips
Supporting three battery approaches lets divers balance runtime, logistics, and equipment preferences. A replaceable battery is especially practical for expedition diving, where carrying spare cells can be more reassuring than relying on a sealed internal design.

We may earn a commission when you buy through this link, at no additional cost to you.
The transmitter title suggests that a wireless pressure unit is associated with the package, while the detailed features describe support for optional wireless tank-pressure transmitters. Buyers should still verify whether one is included and which units are compatible. The computer supports Open-Circuit, Fixed PO2, Gauge, and Freediving modes, giving it flexibility across different breathing and monitoring setups.
Audible and vibration alerts provide two ways to notice important changes, which can be useful in noisy or high-stress conditions. The supplied information does not mention GPS, detailed storage capacity, or a modern AMOLED display. That narrower feature summary means the Teric should be judged primarily on its decompression model, tank integration, alerts, and compact form rather than smart connectivity.
The Teric is a strong recommendation for a diver who wants Shearwater's configurable decompression approach in a relatively traditional wrist computer with confirmed wireless tank support. It is well suited to technical and recreational divers who value alerts and air pressure without a large screen. Confirm the transmitter package before ordering, since accessory details can vary between listings.
Configurable Decompression With Clear Intent
The Bühlmann ZHL-16c model and adjustable gradient factors give divers meaningful control over deco behavior. Those settings are most valuable when they reflect a deliberate personal risk-management strategy rather than arbitrary changes.
Alerts That Suit Different Conditions
Switchable audible and vibration alerts let users choose the notification method that works best in the dive environment. The watch form factor keeps the computer compact while preserving air-pressure information and core dive functions.

Buying Guide – How to Choose the Best Dive Computer with Air Integration
The best dive computer with air integration is not simply the model with the most features. Start with your dive profile, gas use, navigation needs, and reading preferences, then verify whether the transmitter is included and whether the computer supports every mode and accessory you expect to use.
Confirm What Air Integration Includes
Choose the configuration that matches your actual cylinders, not the largest supported number. Single-tank recreational divers can usually keep the setup simple, while technical and sidemount divers may need multiple pressure readings. Always confirm compatibility before buying.
Understand Remaining-Gas Calculations
For technical diving, gas-time estimates and gas-aware decompression are more important than a basic pressure display. For simple recreational use, reliable pressure monitoring and clear remaining-time information may be sufficient.
Match Display Size to Visibility
Choose a large color screen for detailed profiles and surface navigation. Choose a simple monochrome screen for straightforward recreational diving, glare control, and minimal menu complexity.
Review Algorithms and Gas Modes
Match the supported gases and dive modes to your actual experience. Never adopt a complex configuration during a trip without understanding its behavior and practicing with it beforehand.
Check Navigation and Surface Location
Prioritize an underwater compass for navigational safety and dedicated GNSS for remote entries. If both are priorities, choose a model that integrates them without making the wrist unit excessively large.
Evaluate Battery and Charging Logistics
Choose rechargeable power for frequent short trips and replaceable cells for remote or extended use. Check the endurance of the computer and transmitter separately when both are part of the system.
Consider Durability and Wrist Comfort
For deep or technical diving, prioritize the stated depth rating and rugged construction. For everyday wear, balance case size, strap flexibility, and display visibility rather than selecting only on maximum specifications.
Plan for App and Log Connectivity
Prioritize reliable local operation and adequate onboard storage. Use app and cloud connectivity for analysis and sharing when it adds convenience, but do not assume it will be available on every trip.
How to Use and Care for Your Dive Computer with Air Integration
Begin by fully charging the wrist computer and transmitter, installing the pressure unit correctly, and pairing them according to the manufacturer's instructions. Confirm that the displayed cylinder pressure matches the tank gauge or another trusted source before entering the water. Learn the menus, set the correct gas, adjust date and time, verify depth and units, and review the configured algorithm before relying on the computer during a dive.
Treat the digital air estimate as a supporting tool rather than the sole basis for gas decisions. Check the physical gauge, follow a conservative breathing-gas reserve, and account for the possibility that a transmitter battery or radio link may fail. Use the compass, dive profile, and navigation tools as complementary information, and never assume a wrist display replaces disciplined planning or buddy communication.
After the dive, rinse the computer and transmitter with fresh water, paying particular attention to buttons, seals, transmitter contacts, and strap areas. Allow each component to dry before storage, and replace the transmitter battery during the interval recommended by the manufacturer. Download important logs, check for firmware updates when connected to a safe power source, and inspect O-rings, straps, contacts, and cases for damage before the next trip.
Frequently Asked Questions
Does air integration mean the transmitter is included?
No. Air integration describes the ability to receive tank-pressure data wirelessly, but the transmitter may be included, optional, or sold separately. The Garmin Descent X50i and Mk2i explicitly require separate T2 or T1 units, while the Mares Quad Ci supports up to five transmitters without identifying them as included. Always read the package contents and confirm compatibility before purchasing.
How many tanks can a dive computer monitor?
The supported number varies substantially by model. The SCUBAPRO G2 lists support for up to eleven transmitters when all features are activated, the Mares Quad Ci supports five, the Garmin Mk2i supports five, the Shearwater Peregrine TX supports four, and the Teric supports optional wireless transmitters. Confirm the number of units actually included before planning a multi-cylinder setup.
What is the difference between tank pressure and remaining bottom time?
Tank pressure is a direct measurement of cylinder pressure received from the transmitter. Remaining bottom time is an estimate based on consumption and breathing workload, so it can be more useful but also depends on accurate data and assumptions. The SCUBAPRO G2 and Luna 2.0 specifically provide true remaining bottom time calculations, while other models primarily emphasize pressure monitoring.
Can I use GPS while underwater?
GPS is not a practical underwater navigation system, and the Garmin Mk2i listing explicitly states that GPS tracking does not work underwater. A surface GPS transmitter can still help identify entry points and record locations before or after the dive. For underwater direction, use a compass and the dive computer's navigation features.
Are open-circuit and closed-circuit modes the same?
No. Open-circuit diving uses a regulator that delivers gas directly from the cylinder, while closed-circuit rebreather systems recirculate exhaled gas. A computer supporting both can serve more types of diving, but divers should understand the limits of its gas modeling. The SCUBAPRO G2 and Shearwater Perdix 2 Ti list closed-circuit support, while the Teric lists Open-Circuit, Fixed PO2, Gauge, and Freediving modes.
Should I choose a color display or monochrome LCD?
Color displays are useful for graphs, map detail, alerts, and quick visual differentiation, but they can add cost, size, and complexity. A high-contrast monochrome display remains easier to interpret for many recreational divers. The best choice depends on whether you need rich information or a simple layout that keeps critical readings prominent.
How should I maintain a wireless tank transmitter?
Rinse the transmitter with fresh water after every dive, dry it thoroughly, and inspect its contacts and seal for damage. Replace its battery on the manufacturer's recommended schedule and confirm that pressure readings agree with a trusted gauge before each dive. Carry a backup pressure instrument and establish a manual reserve plan in case the electronic link fails.
Do I need to use the manufacturer's app with these computers?
The core dive functions should operate on the wrist, while apps and desktop software are generally used for configuration, downloads, firmware, storage, and analysis. Products such as the SCUBAPRO G2 support USB and Bluetooth transfers, while Shearwater models connect to Shearwater Cloud. Check app compatibility and make sure you can operate the computer safely even when a phone is unavailable.
Final Thoughts on Choosing the Best Dive Computer with Air Integration
The SCUBAPRO G2 is the strongest all-around choice for divers seeking a confirmed bundle, true remaining bottom time, advanced multi-gas calculations, and support for numerous transmitters. The GPS-equipped Shearwater Peregrine TX configuration stands out for surface navigation and multi-constellation positioning, while the Mares Quad Ci offers a more conventional wrist design with five-tank support and configurable decompression settings.
Prioritize the features your dive profile actually requires: confirmed transmitter compatibility for air integration, a readable display, a suitable algorithm and gas mode, dependable battery logistics, and navigation tools that work in the environment where you dive. Large color screens and extensive feature lists can be valuable, but simpler equipment is often easier to understand and maintain. Verify the final package before ordering.
Product configurations, included accessories, software support, and prices can change over time. Review the current listing, manufacturer documentation, and accessory contents at the point of purchase so that the computer and any required transmitter form the system you intended to buy.
