Choosing among dive computers & instruments comes down to a practical split: do you want a console or wrist format, and how much do condition and included extras matter? The four choices here range from a used, untested Suunto Cobra to a used Shearwater Perdix, with two new Cobra console computers between them. The right pick depends on matching the configuration-not just the model name-to your intended setup.
Quick take
The prices span USD 119.95 to USD 500, creating a $380.05 spread. The three Suunto Cobra choices are console computers, while the Shearwater Perdix is a wrist computer. The Cobra entries differ in condition and included details such as a compass, original packaging, and an extra battery. The Perdix takes a different approach with no air integration and visible hardware wear. Start with your required format, then use condition and price to narrow the choice.

Decision matrix
- Lowest price with a compass named: Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested. The title includes both the compass and case, while Used and Untested make condition the key trade-off.
- New console with a broad named feature set: Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console. It is marked New and includes air integration, Nitrox, pressure tracking, alarms, and a user-replaceable battery.
- Extra battery and multiple modes: Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery. Its details specify Air, Nitrox, and Gauge modes along with the extra battery.
- Wrist format without air integration: Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI. The wrist design is the central distinction, but the used condition and broken buckle arms matter.
Product notes
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested
The Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested is a direct match for a shopper who wants the compass named in the model phrase. Its air-integrated console format and included case further define the setup, while its USD 119.95 price is the lowest in this comparison. The limitation is explicit: the item is marked Used and Untested. That condition separates it from the new Cobra entries, even though the model family is similar. Choose it when the compass and lower price are central to the decision; avoid making it the first choice when new condition is essential.
Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console
The Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console fits shoppers who want a new console computer with original packaging. Its feature set includes air integration, tank pressure, depth, time, no-decompression limits, Nitrox, RGBM, audible and visual alarms, and a user-replaceable battery. That creates a clearly specified console-oriented brief. Its limitation is the console format itself: someone seeking a wrist computer will need a different configuration. Choose this Cobra when new condition and the named console package matter more than an extra battery being called out.
Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery
The Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery is the fit when the extra battery is the deciding detail. It is marked New and is described with Air, Nitrox from 21% to 50%, and Gauge modes, plus a bright electroluminescent backlight and audible alarms. Those named modes and the added battery give it a distinct shopping brief. The limitation is still the console format, so it does not suit a shopper whose priority is a wrist computer. Pick it for the extra-battery package and mode selection; choose the new-in-box Cobra instead when original packaging is more important.
Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI
The Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI is the match for a shopper who specifically wants a wrist-format dive computer rather than an air-integrated console. It is identified as the original Gen 1 Perdix, with details placing it in a backup-for-tech-diving role and noting 54 dives. The limitation is physical condition: it is Used, has housing scratches, a screen protector whose deeper wear is uncertain, broken buckle arms, and no box. It is also explicitly without air integration. Choose it for the wrist form and stated configuration; avoid it when intact buckles are required.
Final recommendation by use case
- For the lowest-price compass-equipped console: choose the Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested. The compass and USD 119.95 price fit that brief, but Untested is a decisive condition caveat.
- For a new-in-box console: choose the Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console. Its packaging, New condition, and air-integrated feature set make the intended setup clear.
- For an extra-battery console: choose the Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery. The extra battery and named Air, Nitrox, and Gauge modes are the reasons to favor it.
- For a wrist computer: choose the Shearwater Perdix Wrist Dive Computer - Black - Original OG, NO AI. Its wrist format is distinct, while the used wear, broken buckle arms, and lack of air integration should be accepted as part of the choice.
