Choosing between dive computers & instruments is less about picking a familiar-looking screen and more about matching the instrument to your priorities. Deepblu Cosmiq+ emphasizes dive information for scuba and snorkeling, while Aqualung i330R brings a specifically named console setup and a longer list of functions. The right choice depends on which of those roles fits your dives.
Quick verdict
At USD 289.95 versus USD 300.00, the Deepblu is $10.05 less. That is a narrow gap, so the decision should turn on what each option emphasizes rather than price alone. Choose Deepblu when scuba-and-snorkeling use and dive-profile tracking are the priority. Choose Aqualung when a rechargeable battery or Bluetooth connection matters more to your setup.

Where each product wins
Deepblu Cosmiq+ wins for scuba and snorkeling focus
Deepblu is the stronger match for shoppers looking across scuba and snorkeling, since both activities are directly associated with the Cosmiq+ option. It also keeps the buying decision centered on a dive computer rather than a console arrangement. That makes it a sensible direction for someone who wants dive-profile information and does not need to prioritize a gauge-and-compass setup.
Aqualung i330R wins for the named console arrangement
Aqualung is the more direct fit for a shopper seeking a 2 Gauge Scuba Dive Computer Plus Compass. It is also identified as a PSI dive console, making the instrument arrangement clear. Choose this route when those named components matter more than keeping the decision focused on a general-purpose dive computer.
Product notes
Deepblu Cosmiq+

Deepblu Cosmiq+ centers the decision on information during a dive. It highlights dive-profile tracking, safety-margin calculations, and real-time information, giving it a concrete reason to choose for shoppers who want those functions foregrounded. The New condition is another practical reason to select it in this comparison. Its limitation is visible in the name: the listed version is Purple, so color-sensitive shoppers should treat that as part of the choice. Aqualung offers a different console arrangement, but Deepblu remains the more focused fit for someone shopping around the Cosmiq model and its profile-oriented functions.
Aqualung i330R

Aqualung i330R is the feature-led alternative. Its functions include a bright color screen readable even in sunlight, a rechargeable battery, four modes, three nitrox mixes, and Bluetooth connection. Those details provide concrete reasons to choose it when screen readability or the listed operating functions matter. The limitation is equally concrete: it is Used and has minor cosmetic signs of use. All components are said to function as intended, but that does not remove the cosmetic qualification. This makes Aqualung a fit for shoppers weighing a defined console feature set rather than choosing solely on the product name.
Final choice by use case
For scuba or snorkeling, choose Deepblu Cosmiq+ when dive-profile tracking, safety-margin calculations, and real-time information are your priority. For the explicitly named 2 Gauge Scuba Dive Computer Plus Compass arrangement, choose Aqualung i330R. The final split is straightforward: Deepblu suits the profile-information focus, while Aqualung suits the console-and-compass setup with its additional named functions.
