Choosing the right dive computers & instruments starts with a practical question: do you need an air-integrated console, a compass in the console, a computer for scuba and snorkeling, or controls for multi-gas and technical diving? Price and condition matter just as much: the four choices span USD 119.95 to USD 289.95, a $170.00 spread, and include both Used and New condition labels.
The useful shortcut is to match the computer to your dive plan before comparing names. The Suunto Cobra choices center on console formats, Deep 6 Excursion lists detailed gas and decompression controls, and Deepblu Cosmiq+ emphasizes profile tracking, safety margins, and real-time information.
Quick take
Start with condition and format, then decide whether navigation, console readouts, profile information, or gas controls matter most. The prices are far enough apart that the lowest figure alone does not identify the right fit. The matrix below sorts the four choices before the individual tradeoffs.

Decision matrix
- Air-integrated console: The two Suunto Cobra titles explicitly use air-integrated wording. The first Suunto title also names a compass console, while the new-in-box Cobra description lists tank-pressure tracking and Nitrox compatibility.
- Technical gas planning: Deep 6 Excursion is described with multi-gas Nitrox, Helitrox capability, a Bühlmann ZHL-16C algorithm, user-settable gradient factors, and several dive modes.
- Scuba and snorkeling: Deepblu Cosmiq+ is described for both activities and emphasizes tracking dive profiles, calculating safety margins, and displaying real-time information.
- Condition: The first Suunto Cobra is marked Used and Untested; Deepblu Cosmiq+, the new-in-box Suunto Cobra, and Deep 6 Excursion are marked New. Treat that distinction as a primary filter before comparing features.
Product notes
Deepblu Cosmiq+ SCUBA Dive Computer - Purple
Deepblu Cosmiq+ SCUBA Dive Computer - Purple is the highest-priced choice, and its condition is New. The description highlights a user-friendly interface, tracking dive profiles, calculating safety margins, and providing real-time information. Those details give it a clear reason to choose when readable, ongoing dive information matters across an underwater outing. The limitation is its price position: at USD 289.95, it sits above the other three choices, including the USD 199.00 Deep 6 Excursion. The purple finish is also part of the named configuration, helping distinguish it from the other computers in this comparison.
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested is the lowest-priced choice. Its title gives shoppers three concrete cues: air integration, a compass console, and a protective case. The case is the clearest practical reason to choose this specific configuration if that included format suits your setup. The limitation is explicit in the title and condition: it is marked "Untested" and classified as Used. That makes condition the central tradeoff, especially beside the three choices marked New. The description also frames it for experienced divers, so it is not the same buying decision as a new-in-box console.
Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console
Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console is the new Suunto choice at USD 195.49. Its description names tank-pressure, depth, time, and no-decompression-limit tracking, along with Nitrox compatibility, audible and visual alarms, a user-replaceable battery, and a large display. Choose it when those console-readout functions are more important than selecting a different computer format. The limitation is also format-specific: the description calls it console-mounted and hose-mounted, so it is built around that arrangement. It costs USD 75.54 more than the Used, Untested Cobra with compass.
Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New
Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New carries a New condition and a USD 199.00 price. The concrete reason to choose it is the named control set: multi-gas Nitrox from 20% to 99% across four gases, Helitrox up to 22% helium, the Bühlmann ZHL-16C algorithm, user-settable gradient factors, and scuba, planning, apnea/free-diving, and gauge modes. Bluetooth, variable brightness, and a fast-charging mode add practical controls. The limitation is price positioning: USD 199.00 is USD 3.51 above the new Suunto Cobra, so choose it for the listed feature set rather than the lower price.
Final recommendation by use case
- For the lowest listed price: choose Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested. Its title makes the compass-console format clear, while the Used and Untested wording is the key tradeoff.
- For a new air-integrated console: choose Suunto Cobra Air-Integrated Scuba Dive Computer - NEW in Box - Console when the new condition and console readouts align with your setup.
- For the recreational-and-technical diving use case: choose Deep 6 Excursion Scuba Dive Computer for Recreational and Technical Diving New for the feature set named in its description.
- For scuba and snorkeling use: choose Deepblu Cosmiq+ SCUBA Dive Computer - Purple if its user-friendly interface and real-time information are the deciding factors.
The central choice is therefore not simply the cheapest or most feature-heavy computer. It is whether your priority is a new console, a lower listed price, explicit technical controls, or a broader scuba-and-snorkeling focus.
