Quick take
Choosing among dive computers & instruments comes down to one immediate fork: do you want air integration in a console, a computer with explicitly listed multi-gas and technical-diving features, or a used kit with accessories? The four choices here cover those priorities without occupying the same lane.
The Deep 6 Excursion stands out for its listed Nitrox, Helitrox, multiple modes, and gradient-factor controls. The two Suunto Cobra choices focus on air-integrated console use, with the lower-priced version also naming a compass and case. The Oceanic Atom 3.1 is a used computer paired with a substantial accessory bundle. Condition and price are important tie-breakers: the listed-price span is $130.05, from $119.95 to $250.
Listed-price comparison
| Product | Listed price | Price bar |
|---|---|---|
| Deep 6 Excursion Scuba Dive Computer | USD 199.00 | |
| Suunto Cobra Air Integrated Scuba Dive Computer Compass Console with Case Untested | USD 119.95 | |
| Suunto Cobra Air-Integrated Scuba Dive Computer, New in Box | USD 195.49 | |
| Oceanic Dive Computer - USed, 4-5 Dives Only | Full Kit | Factory Screen Pro | USD 250.00 |
Price separates the choices, but the feature match is more useful than the number alone. The Suunto Cobra marked untested has the lowest listed price, while the Oceanic carries the highest. The two new choices sit close together, with the Deep 6 Excursion at $199 and the new-in-box Suunto Cobra at $195.49.
Decision matrix
- Multi-gas, Helitrox, and several dive modes: Deep 6 Excursion, with Nitrox from 20%-99%, four gases, Helitrox capability up to 22% helium, and scuba, planning, apnea/free-diving, and gauge modes.
- Air integration plus a compass and case: Suunto Cobra Air Integrated with compass, console, and case. Its untested condition is the key limitation.
- New-in-box air-integrated console: Suunto Cobra Air-Integrated, whose description names tank-pressure, depth, time, no-decompression-limit tracking, alarms, and a user-replaceable battery.
- Computer with included accessories: Oceanic Atom 3.1, with an extra strap, extra battery, battery-change tool, PC interface cable, CD, box, and paperwork.
Product notes
Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New
The Deep 6 Excursion is the clearest match for a diver who wants its explicitly listed multi-gas and technical-dive tools. It supports Nitrox from 20%-99% across four gases, Helitrox up to 22% helium, a Bühlmann ZHL-16C algorithm, user-settable gradient factors, and scuba, planning, apnea/free-diving, and gauge modes. Bluetooth, variable brightness, and fast-charging are also named. The limitation is cost relative to the group: at $199, it sits $79.05 above the $119.95 Suunto Cobra console, making it less suited to a shopper whose first filter is the lowest listed price.
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested makes sense when a console, air integration, compass, and protective case are central to your choice. Its $119.95 price is the lowest among the four, creating a $130.05 spread to Oceanic's $250. The limitation is explicit: the unit is used and marked untested. That condition matters to the decision, so the Cobra is a lower-priced route for someone deliberately weighing those listed features against the untested status. The named compass detail keeps the selection specific rather than generic.
Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console
Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console is the straightforward condition-led choice: new in box, never used, original factory packaging, manuals, and accessories included. Its description names a hose-mounted console, tank-pressure, depth, time, no-decompression-limit tracking, Nitrox compatibility, alarms, and a user-replaceable battery. Choose it when those air-integrated console functions matter and new condition is a priority. The trade-off is its $195.49 price, which is $75.54 above the used, untested Cobra at $119.95. Both carry Cobra Air-Integrated naming, so condition and the explicitly listed package details drive the distinction.
Oceanic Dive Computer - USed, 4-5 Dives Only | Full Kit | Factory Screen Pro
Oceanic Atom 3.1 is the pick for someone who wants an included accessory set around a used computer. The description names an extra unused strap, extra battery, battery-change tool, PC interface cable, CD, box, and paperwork, while the title identifies 4-5 dives and a factory screen protector. The limitation is price: $250 is the highest listed amount, and the condition remains used even with that short stated dive history. Its model-specific identity helps shoppers seeking an Oceanic Atom 3.1 rather than a generic dive instrument. Choose it when the accessory bundle carries real weight in the decision.
Final recommendation by use case
- For multi-gas Nitrox, Helitrox, and varied dive modes: choose the Deep 6 Excursion. Its recommendation is tied to the named gas support, gradient-factor controls, and mode selection.
- For air integration, a compass, and the lowest listed price: choose the Suunto Cobra with compass and case, while treating its used, untested condition as the central limitation.
- For a new-in-box air-integrated console: choose the new Suunto Cobra. It offers the clearest condition match and explicitly listed tank-pressure, depth, time, and no-decompression-limit tracking.
- For an Oceanic Atom 3.1 with accessories: choose the Oceanic kit if the extra battery, tools, interface cable, and paperwork justify its $250 listed price.
In short, start with the feature you will actually use: advanced gas and mode support points to Deep 6, console air integration points to either Suunto, and included accessories point to Oceanic. Then use condition and the $130.05 price span to settle the final choice.
