When choosing dive computers & instruments, the hard part is matching the instrument to the dive rather than simply picking the lowest listed price. Do you want a wrist-watch computer with a transmitter, an air-integrated console, a compass built into the console, or multi-gas and technical controls? Condition also changes the decision: the group includes new items, used items, and one explicitly described as untested.
Quick take
Start with the function that matters most, then use condition and price to narrow the choice. The Oceanic and two Suunto models take different computer-and-console approaches, while the Deep 6 Excursion emphasizes recreational and technical diving. The listed prices span $119.95 to $325, so the absolute spread across the group is $205.05.

Product notes
Oceanic Atom 2.0 Dive Computer Watch Air Integrated Nitrox With Transmitter
The Oceanic Atom 2.0 is the wrist-watch package in this comparison. Its description names a transmitter, USB download/upload cable, extension strap, watch-face protector, manuals, and a safety reference manual. That accessory set gives shoppers a concrete reason to choose it when included equipment matters alongside the computer. The limitation is the condition and age described: it is used and identified as an older model. The computer has new batteries, but the transmitter needs batteries supplied separately. That battery detail matters for shoppers who want the air-integrated setup without overlooking an additional power requirement.
Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery
The Suunto Cobra Dive pairs a new-condition console with RGBM, Air, Nitrox, and Gauge modes, plus an extra battery. Its description also specifies Nitrox from 21%-50%, an electroluminescent backlight, and audible alarms for ascent rate, depth limits, and safety stops. Those are concrete reasons to choose it when readable console information and multiple modes matter. The limitation is the stated Nitrox range: 21%-50% is a different specification from the Deep 6 Excursion's separately stated 20%-99%, so the two should not be treated as interchangeable. The extra battery is another practical part of the Cobra package.
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested
The Suunto Cobra Air Integrated Scuba Dive Computer Compass Console is the focused navigation choice. The product title names both air integration and a compass, and it includes a protective case, giving shoppers a concrete reason to choose it when compass information and a case belong in the same selection. The limitation is explicit: the item is listed as used and untested. That condition makes it a fit for shoppers comfortable with an untested instrument rather than those who want a new-condition purchase. The case and compass-console wording remain the clearest reasons to select this particular Suunto route.
Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New
The Deep 6 Excursion takes a specialized route, with multi-gas Nitrox from 20%-99% for four gases, Helitrox capability up to 22% helium, and a Bühlmann ZHL-16C algorithm. Bluetooth logging and updates, variable-brightness backlighting, fast charging up to 85% in one hour, and Scuba, Planning, Apnea/Free Diving, and Gauge modes give shoppers specific reasons to choose it for those functions. The limitation is that its feature set is more specialized: someone seeking a simple recreational setup may not need gradient-factor controls, tissue graphs, or multiple gas modes. It is listed as new and identified for recreational and technical diving.
Final recommendation by use case
- Wrist-watch setup: Choose the Oceanic Atom 2.0 if the title's "With Transmitter" package and accessory set are the priority. Its USD 325.00 price is the highest here, and the used, older description plus separate transmitter batteries are the trade-offs.
- New air-integrated console: Choose the Suunto Cobra Dive at USD 200.00 when new condition, an extra battery, and its defined console modes fit the plan.
- Compass-console route: Choose the Suunto Cobra Air Integrated model at USD 119.95 when the compass and case matter most. The used, untested condition should be accepted as part of that choice.
- Multi-gas or technical diving: Choose the Deep 6 Excursion at USD 199.00 when its stated Nitrox, Helitrox, and planning features match the intended use; its specialized controls are less appropriate for shoppers seeking a simpler setup.
