Choosing dive computers & instruments starts with a setup decision: do you want a console-mounted computer with air integration and a compass, or a wrist computer with a different feature mix? These four choices also span used, untested, and new-in-box condition, so the right pick depends on how much the format and condition matter to you-not just the model name.
Quick take
- For a console with compass, rechargeable power, and multiple dive modes: the Aqualung i330R is the most feature-specific match.
- For a new-in-box air-integrated console: the Suunto Cobra Air-Integrated Scuba Dive Computer is the straightforward choice.
- For a used console with a named compass and protective case: the Suunto Cobra Air Integrated is the lower-priced format match, with an untested condition attached.
- For a wrist computer: the Shearwater Perdix is the only choice here explicitly identified as a wrist model, but it is marked NO AI and has visible hardware limitations.
Listed-price comparison
The listed prices run from $119.95 to $500, a $380.05 gap between the lowest and highest choices. That spread makes it useful to separate console format, condition, and air-integration needs before comparing models.

Decision matrix
- Choose by mounting format: The Aqualung and both Suunto Cobra titles identify console setups. The Shearwater title identifies a wrist dive computer.
- Choose by air integration: Air integration is explicit for both Cobra choices. The Shearwater title explicitly says NO AI, while the Aqualung is described as a PSI console with compass.
- Choose by navigation: A compass is named with the Aqualung and both Cobra choices, making those the clearest matches when compass wording matters.
- Choose by condition: The Aqualung, used Cobra, and Perdix are marked used. The other Cobra is marked new and described as new in box.
Product notes
Aqualung i330R 2 Gauge Scuba Dive Computer Plus Compass
The Aqualung i330R is a console choice for divers who want a compass alongside a PSI dive computer. Its feature set includes a bright color screen, rechargeable battery, four modes, three nitrox mixes, and Bluetooth connection. That combination gives it a broader feature profile than a basic computer-and-compass pairing. The tradeoff is its used condition, with minor cosmetic signs of use noted on the console. Choose it when those specific display, battery, and mode features matter more than having a new-in-box unit. Its $300 listed price also places it between the two Cobra choices and the Shearwater Perdix.
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested
This Suunto Cobra combines three concrete setup cues in its title: air integration, a compass, and a console with case. It is the clearest choice for someone seeking that particular combination without moving to a wrist format. The limitation is equally prominent: the unit is marked untested and used. That condition creates more uncertainty than the new-in-box Cobra, even though both use the Cobra air-integrated console format. The protective case is a useful included detail for storage, while the compass wording supports a navigation-focused console decision. Its $119.95 listed price is the lowest in the comparison.
Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console
The new-in-box Suunto Cobra is the direct match for a buyer who wants a console-mounted computer with air integration and a new condition. Its feature list includes tank-pressure, depth, time, and no-decompression-limit tracking, plus nitrox compatibility, audible and visual alarms, a user-replaceable battery, and a large display. The limitation is the console format itself: this is a hose-mounted unit rather than a wrist computer. At $195.49, it sits below the Aqualung and well below the Shearwater while offering the most clearly stated new condition among the console choices.
Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI
The Shearwater Perdix stands apart on format: it is explicitly a wrist dive computer, and its title identifies it as the Original OG model without air integration. That makes it the natural fit for a buyer who specifically wants a wrist-mounted computer and accepts the NO AI configuration. The limitations are substantial and concrete: it is used, the housing has scratches, the screen protector has scratches, and the buckles are broken with only one arm on the male end. It also comes without a box, with the description offering blue bungees as a possible strap solution. The $500 listed price is the highest here.
Final recommendation by use case
- New-in-box console: Choose the Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console for its explicit condition, console format, and air-integration description.
- Lowest listed price: Choose the Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested if its compass-and-case combination fits and the untested condition is acceptable.
- Feature-rich console setup: Choose the Aqualung i330R 2 Gauge Scuba Dive Computer Plus Compass for its rechargeable battery, bright color screen, four modes, nitrox support, and Bluetooth connection.
- Wrist format: Choose the Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI when a wrist computer is the priority and its used condition, broken buckles, and no-AI configuration fit your setup.
