Quick take
Choosing dive computers & instruments is less about picking the biggest screen and more about matching the setup to how you dive. Do you want a watch-style computer, a console, a compass, or a wrist unit designed around a different setup? Condition matters too: the four choices range from new to used, untested, and visibly worn. Price alone does not settle the fit. Compare format first, then weigh the package and condition attached to each choice.

Product notes
Oceanic Atom 2.0 Dive Computer Watch

The Oceanic Atom 2.0 is the clearest match for a watch-style setup that includes a transmitter in the package. The bundle also includes a USB download/upload cable, watchface protector, extension strap, manuals, and a battery already installed in the computer, giving the package a defined set of extras. The unit is used but characterized as like new and fully functional after checkout dives. The important limitation is the transmitter battery: the buyer needs to provide batteries for it. The package also includes only one watch lens guard, so accessory quantities are not entirely identical across the bundle. At $325, it sits above both Suunto choices.
Suunto Cobra Dive Computer Air Integrated Console

Suunto Cobra Dive Computer is the straightforward pick for a new console with a clearly described operating set. It supports Air, Nitrox from 21% to 50%, and Gauge modes, while the unit includes RGBM decompression, real-time tank-pressure monitoring, a backlight, audible alarms, and an extra battery. Those details suit a diver who wants the stated modes and readouts in a console format. Its limitation is format: this is a console rather than a wrist-watch computer, so it does not serve the same wear-on-the-wrist role as the Oceanic or Shearwater. The price sits in the middle of the four choices at $200, not at either end.
Suunto Cobra Air Integrated Compass Console

Suunto Cobra Air Integrated Scuba Dive Computer Compass Console stands out for the combination stated in its name: air integration, a compass, and a protective case. That makes it the most direct match for someone prioritizing navigation equipment alongside a console-style dive computer. The trade-off is explicit: it is used and untested. That condition should remain central to the decision rather than being treated as proof of operation. At $119.95, it is the lowest listed price in this comparison, yet the lower entry point comes with that condition concern. Choose it only when the compass-and-case package matters enough to accept the uncertainty.
Shearwater Perdix Wrist Dive Computer

Shearwater Perdix Wrist Dive Computer fits a buyer seeking the Original OG model without air integration. It has 54 dives, giving the buyer a specific history to weigh. The concrete physical limitation is the buckle condition: the buckles are broken, with only one arm on the male end. Scratches are reported on the housing, and the screen protector is scratched while the underlying screen is not confirmed. The package is computer-only, with blue bungees possibly included, so it is not an accessory-rich bundle. At $500, it is also the highest listed price, making the physical wear especially important to factor into the decision.
Final recommendation by use case
- Watch format: Choose the Oceanic Atom 2.0 Dive Computer Watch.
- New console: Choose the Suunto Cobra Dive Computer Air Integrated Console.
- Compass and case: Choose the Suunto Cobra Air Integrated Compass Console only if its untested condition fits your tolerance.
- Wrist computer: Choose the Shearwater Perdix Wrist Dive Computer when the Original OG, NO AI configuration is the intended setup and the broken buckles are workable.
The best match here is determined by the setup you want to wear or connect, not simply by the $380.05 price spread. The Suunto Cobra with compass has the lowest entry price, while the Shearwater asks the most and carries the clearest physical-repair concerns. The Oceanic and new Suunto Cobra occupy the more defined package paths for watch and console buyers.
