Choosing dive computers & instruments is a practical matching exercise: the right pick depends on how you weigh format, condition, and included equipment. Here, listed prices span $119.95 to $325, with choices that differ in condition, format, and package details. Start with the decision map below, then use the product notes to weigh each tradeoff.
Quick take
The listed price range is $119.95 to $325. That spread makes condition and included equipment as important as the headline number. A careful choice starts with the format you want, then the named function or accessory that matters for your dives, and finally the condition wording. The product notes below keep those tradeoffs separate instead of treating every dive computer as interchangeable.

Decision matrix
Use these filters in order:
- Format: Decide how you want the computer presented for your setup before weighing extras.
- Capability: Give priority to the function or accessory stated most clearly in the product title rather than assuming an unmentioned feature.
- Condition: Separate Used, New, and New OPEN BOX before comparing prices.
- Price: Use the exact figures in the table as a tie-breaker, but do not let a lower figure erase an untested caveat.
Product notes
Oceanic Atom 2.0 Dive Computer Watch Air Integrated Nitrox With Transmitter
The Oceanic Atom 2.0 is the clearest match for a wrist-mounted setup that combines air integration, Nitrox, and a transmitter in the product name. The package includes the transmitter, USB download/upload cable, extension strap, manuals, and a watchface protector, reinforcing its watch-style format. The tradeoff is condition: it is a used, older model rather than a new unit. The transmitter also needs batteries supplied separately. Choose it when the wrist-watch format and explicitly named transmitter matter most; its limitation is that the accessory package still leaves transmitter batteries for the buyer to provide.
Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery
Suunto Cobra Dive is the console-oriented choice for shoppers who want a named mix of air integration, RGBM decompression, Nitrox, Gauge mode, and an extra battery. Its Nitrox range is 21%-50%, and it also has an electroluminescent backlight, audible alarms, altitude adjustment up to 10,000 feet, and a 492-foot depth rating. Those numbers are scope markers, not promises of performance. The limitation is format: the title presents a console rather than a wrist-watch computer. Its New condition makes it a direct fit when a console and the named functions align.
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested is the clearest fit for a compass-console brief. A protective case is part of the package, and the title directly calls out air integration and compass capability. Its concrete limitation is the word Untested, alongside Used condition: operation has not been established. That caveat matters more than the price if dependable readiness is your priority. Choose this Suunto when the compass-console format and lower price come first, and accept that untested status is the defining compromise.
AquaLung i330R Dive Computer NEW OPEN BOX
AquaLung i330R Dive Computer NEW OPEN BOX suits a shopper who puts new condition ahead of a named wrist-watch or console format. It was powered on to verify function and has never been used in water, giving the choice a clear open-box distinction. The limitation is its use history: the unit has only been powered on to verify function, rather than used in water. That makes it a less direct match for a shopper who specifically wants an in-water use history. Choose it when the i330R model phrase and open-box condition fit your priorities.
Final recommendation by use case
- For a watch-style transmitter package: Choose the Oceanic Atom 2.0. Its title directly matches that brief, with the separate transmitter-battery requirement as the main caveat.
- For a console with Nitrox and an extra battery: Choose Suunto Cobra Dive. The New condition and named console functions make the match direct.
- For a compass-console setup: Choose Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested when its compass and case matter more than the Used, untested status.
- For a New OPEN BOX model: Choose AquaLung i330R when its model phrase and power-on verification history fit better than the named features of the other choices.
The strongest match depends on the feature or format you will actually use. Treat the exact condition wording as a deciding factor, especially for the two products carrying Used or open-box caveats.
