Choosing dive computers & instruments means balancing three questions: do you need air integration, do you prefer a console that shows tank pressure, or are you choosing around a specific computer format and condition? The four listed prices span $200 to $899.99, a $699.99 spread, so the useful comparison is package contents and named functions-not price alone.
Quick take
- Wireless transmitter package: Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger.
- Console and tank-pressure focus: Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery.
- 55mm computer format: Shearwater Teric Dive Computer Black 55mm.
- Named model in new open-box condition: AquaLung i330R Dive Computer NEW OPEN BOX.

Decision matrix
- If the deciding item is an included transmitter: The Shearwater Teric package explicitly includes an air-integration transmitter and charger.
- If tank pressure is central: The Suunto Cobra is identified as an air-integrated console with real-time tank-pressure monitoring and an extra battery.
- If physical selectors matter: The black Shearwater Teric lists a 55mm case, silicone band, and Android compatibility.
- If named dive modes matter: The transmitter package lists Air, Nitrox, Trimix, Tech, CCR, and Freediving modes, while the Suunto Cobra lists Air, Nitrox from 21% to 50%, and Gauge modes. These are different named mode sets, not an automatic performance ranking.
- If condition is the priority: The Suunto Cobra and AquaLung i330R are listed as new, while both Shearwater Teric entries are used; the AquaLung is specifically described as new open box.
Product notes
Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger
The Shearwater Teric package with transmitter is the direct choice when wireless air integration is central. It includes the transmitter and charger, and its named features include a full-color AMOLED display with sapphire crystal, digital compass, Bluetooth connectivity, wireless rechargeable battery, and audible and vibration alerts. The listed modes cover Air, Nitrox, Trimix, Tech, CCR, and Freediving, while the stated depth rating is 200 m / 660 ft. The concrete trade-offs are its used condition and highest listed-price position among the four. Choose it for the included transmitter and broad named mode set, not simply because it carries the Teric name.
Shearwater Teric Dive Computer Black 55mm
The black Shearwater Teric suits shoppers narrowing their choice by a defined computer size and included accessories. It lists a 55mm case, silicone band, Android compatibility, multi-gas decompression, a Genuine Charger, a case, documents, and a 15001 M/L band. Those specifics make it a focused Teric purchase for someone who wants that configuration. Its limitation is that it is used, along with a $424.99 listed-price gap above the Suunto Cobra. That makes the case size, silicone band, Android compatibility, and Teric model the concrete reasons to select it, while condition and price remain the main constraints.
Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery
The Suunto Cobra is the clearest match for a console setup centered on pressure information. It combines an air-integrated console with real-time tank-pressure monitoring, RGBM decompression, Nitrox support, an extra battery, a bright electroluminescent backlight, and audible alarms for ascent rate, depth limits, and safety stops. Its named modes are Air, Nitrox from 21% to 50%, and Gauge. The limitation is scope: that mode set differs from the Shearwater transmitter package's named Trimix, Tech, CCR, and Freediving modes. Choose the Cobra when its console format, pressure monitoring, Nitrox support, and extra battery align with your needs; its listed condition is new.
AquaLung i330R Dive Computer NEW OPEN BOX
The AquaLung i330R suits a shopper who wants a clearly identified model in new open-box condition. It was powered on to verify function and never used in water, while the title keeps the choice centered on the i330R rather than a bundled transmitter or console. The practical limitation is the $79 listed-price gap above the Suunto Cobra, plus the open-box condition itself. That makes this a model-and-condition decision: choose it when the AquaLung name and i330R designation matter more than the Cobra's explicitly described air-integrated console, tank-pressure monitoring, RGBM Nitrox support, and extra battery.
Final recommendation by use case
- Wireless air integration with a transmitter included: Choose the Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger.
- Console pressure monitoring and an extra battery: Choose the Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery.
- A 55mm Teric with silicone band and Android compatibility: Choose the Shearwater Teric Dive Computer Black 55mm.
- The i330R model in new open-box condition: Choose the AquaLung i330R Dive Computer NEW OPEN BOX.
The deciding trade-off is package specificity versus listed-price position. Match the computer to the named feature, mode set, console format, or condition that matters for your dive plan rather than treating the price range as a ranking.
