Choosing dive computers & instruments is less about picking a single feature and more about matching the console to the way you dive. Air integration, a compass, multi-gas modes, rechargeable power, and price pull the decision in different directions. The fastest way to narrow these four is to decide whether included air hardware, compass use, a specific Teric configuration, or the lowest listed price matters most.
Quick take
- Shearwater Teric with transmitter: The most fully specified package, with the transmitter and charger included alongside an extensive mode list.
- Shearwater Teric Black 55mm: A more specific Teric configuration with a 55mm case, silicone band, charger, and case.
- Suunto Cobra: The New, lowest-priced choice with an air-integrated console, Nitrox support, and an extra battery.
- Aqualung i330R: A Used console that explicitly pairs a dive computer with two gauges and a compass.

Decision matrix
- Need the broadest named dive-mode set: The Shearwater Teric package lists Air, Nitrox, Trimix, Tech, CCR, and Freediving modes, along with the transmitter.
- Need a console with tank-pressure monitoring: The Suunto Cobra combines an air-integrated console with real-time pressure monitoring and Air, Nitrox, and Gauge modes.
- Need a compass called out directly: The Aqualung i330R configuration names a compass alongside two gauges.
- Need a specific case and band combination: The Black 55mm Teric lists a 55mm case and silicone band, plus Android compatibility.
- Need to weigh condition: Suunto is marked New; the Shearwater and Aqualung choices are marked Used.
Product notes
Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger
Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger is the clearest fit when the transmitter matters: the package includes wireless air integration, the transmitter, a wireless charging station, and a charger. Features include a full-color AMOLED display, sapphire crystal, digital compass, Bluetooth, rechargeable battery, audible and vibration alerts, and Air, Nitrox, Trimix, Tech, CCR, and Freediving modes. Its depth rating is 200 m / 660 ft. The main limitation is its Used condition and highest listed price. Choose it when the included transmitter and mode set fit the planned dives.
Shearwater Teric Dive Computer Black 55mm
Shearwater Teric Dive Computer Black 55mm suits a shopper who wants the Teric configuration identified by its 55mm case and silicone band. The package includes the computer, charger, M/L band, case, and documents, while Android compatibility and multi-gas decompression are also specified. The named contents do not include an air-integration transmitter, unlike the other Teric package. That package distinction is the important limitation when comparing the two Shearwater choices. It is also marked Used. Choose this version when the 55mm format, silicone band, and Teric computer matter more than having a transmitter included.
Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery
Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery combines air-integrated console wording, RGBM Nitrox, and an extra battery in its product name. It supports Air, Nitrox from 21%-50%, and Gauge modes, with real-time tank-pressure monitoring, an electroluminescent backlight, audible alarms, altitude adjustment up to 10,000 ft / 3,000 m, and a logbook storing up to 36 hours of dive profiles. It is the New choice in this group and has the lowest listed price. Its concrete trade-off is the operational display limit of 262 ft / 80 m alongside a 492 ft / 150 m depth rating.
Aqualung i330R 2 Gauge Scuba Dive Computer Plus Compass
Aqualung i330R 2 Gauge Scuba Dive Computer Plus Compass is the direct match for a compass-led setup: the configuration explicitly names two gauges and a compass. Additional features include a bright color screen, rechargeable battery, Bluetooth connection, four modes, and three Nitrox mixes. At the $300 level, it sits below both Teric entries while offering a clearly named compass combination. The limitation is its Used condition, with minor cosmetic signs of use described. Choose it when the two-gauge-and-compass configuration is more relevant than the transmitter-inclusive package.
Final recommendation by use case
- For an included air-integration transmitter: Choose the Shearwater Teric Dive Computer w/ Air Integration Transmitter, Charger at USD 899.99.
- For the lowest listed price: Choose the Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery at USD 200.00.
- For a compass-centered console: Choose the Aqualung i330R 2 Gauge Scuba Dive Computer Plus Compass at USD 300.00.
- For the specific 55mm Teric setup: Choose the Shearwater Teric Dive Computer Black 55mm at USD 624.99.
The decision is therefore straightforward once the priority is clear: included transmitter hardware favors the first Teric package, the lowest price favors Suunto, compass wording favors Aqualung, and the 55mm case points to the second Teric.
