Choosing dive computers & instruments is less about picking the most feature-heavy console and more about matching the setup to the dive: do you need a compass named on the console, air integration, a new-in-box unit, or a bundled accessory kit? The four choices here cover those priorities differently, and price alone does not settle the condition question-one console is explicitly marked "Untested," while another is New in Box.
The useful shortcut is to identify the feature or condition that matters most, then use price as a tie-breaker. A compass-equipped console, an air-integrated Suunto, and an Oceanic accessory bundle serve different shopping priorities before model details enter the decision.
Quick take
Start with your non-negotiable: compass wording, air integration, new condition, or included accessories. Compass wording appears in the Aqualung and used Suunto product names. Air integration appears in both Suunto names, while the Oceanic Atom 3.1 is the choice with the most clearly itemized extras. The used Suunto carries the explicit "Untested" designation, making condition especially important when comparing the lower-priced choices.
Listed-price comparison
| Product | Listed price | Price bar |
|---|---|---|
| Aqualung i330R | USD 300.00 | |
| Suunto Cobra Air Integrated - Untested | USD 119.95 | |
| Suunto Cobra Air-Integrated - New in Box | USD 195.49 | |

Decision matrix
- Compass-first console: Choose the Aqualung i330R when the "2 Gauge" and "Plus Compass" wording is central to the purchase.
- Air integration plus compass wording: The used Suunto Cobra Air Integrated combines both phrases with a protective case, but its "Untested" designation needs to remain part of the decision.
- New-in-box air integration: The Suunto Cobra Air-Integrated is the direct match for a new console with tank-pressure, depth, time, and no-decompression-limit tracking.
- Accessory-kit priority: The Oceanic Atom 3.1 suits shoppers who want the computer alongside an extra strap, battery, tools, interface cable, and paperwork.
Product notes
Aqualung i330R
The Aqualung i330R is a natural fit for a diver who wants a 2 Gauge console paired with a compass. Its console also has a bright color screen, rechargeable battery, four modes, three nitrox mixes, and Bluetooth connection. The used console was part of a regulator set that received a full service and has not been used since that service, giving the purchase a concrete service-history detail. The limitation is the USD 300.00 price, the highest in this comparison, plus minor cosmetic signs of use. Choose it when that named console layout and compass matter more than choosing a lower-priced unit.
Suunto Cobra Air Integrated - Untested
Suunto Cobra Air Integrated gives a direct low-price route to a console that names both air integration and a compass, and its protective case is part of the package. The USD 119.95 price is the lowest in the comparison, making it the price-led choice for shoppers who want those named features. The important limitation is equally clear: the word "Untested" appears in the product title. It is also a used unit, so condition belongs in the decision rather than at the margins. Choose it when the compass, case, and air-integrated console format are the draw and the untested designation is acceptable.
Suunto Cobra Air-Integrated - New in Box
Suunto Cobra Air-Integrated is a direct match for a new-in-box purchase. It tracks tank pressure, depth, time, and no-decompression limits, and includes nitrox compatibility, audible and visual alarms, a user-replaceable battery, and a large display. Its condition is New, with original factory packaging, manuals, and accessories. The trade-off for a compass-first buyer is that the product name focuses on an air-integrated console rather than naming a compass. At USD 195.49, it occupies a middle point in the group. Pick it when new condition and the named air-integrated functions outrank a compass-first requirement.
Oceanic Atom 3.1 Dive Computer
Oceanic Atom 3.1 fits a shopper who wants a named model accompanied by an accessory bundle. The included extras are concrete: an unused extra strap, extra battery, battery-change tool, PC interface cable, CD, box, and paperwork. The title also calls out use on 4-5 dives and a factory screen protector, while the condition is Used. The trade-off is the USD 250.00 price, above both Suunto choices, and the bundle may be unnecessary if the computer alone is the priority. Choose it for the Atom 3.1 identification and included gear rather than for a compass or air-integration requirement.
Final recommendation by use case
For shoppers making price the first filter, the used Suunto Cobra Air Integrated is the direct pick, provided its "Untested" status is acceptable. For a new-in-box air-integrated console, choose the Suunto Cobra Air-Integrated. The Aqualung i330R is the focused choice for the named 2 Gauge and compass format, while the Oceanic Atom 3.1 is better aligned with a computer-plus-accessories purchase. When two priorities compete, condition separates the Suunto choices, while console format and included gear separate the Aqualung and Oceanic options.
