"Gas switches" is how many different mixes this computer can be programmed to switch between mid-dive, mostly relevant for technical/staged-decompression diving. It doesn't tell you which gas types (air, nitrox, trimix) are supported. See Gas types and the product description above for that.

Pros
  • Budget price for a Bluetooth, app-connected computer
  • 200-dive logbook with sync to the Deepblu social dive-log app
  • Rechargeable via magnetic USB cable, up to 10 hours of dive time per charge
Diver community sentiment
Mixed opinions

Divers on Scubaboard describe the Cosmiq+ as an affordable, simple, app-configured computer with an easy setup and a bright interface, and some owners report trouble-free use over many dives. A recurring and more serious thread involves reliability failures, though: multiple users report false/phantom depth readings (one logging a dive to over 1,000 feet), phantom dives recorded during surface intervals, screen problems (condensation, fogging), and charging-contact issues. Customer support is repeatedly described as slow or dismissive, and Deepblu's business troubles and eventual closure add to the negative reputation. Consensus: fine as a cheap, basic computer for some owners, but enough recurring complaints from others that Scubaboard regulars frequently advise caution.

Summarized from public forum discussion (Scubaboard, Reddit, and similar), not a survey we ran ourselves. See the linked threads for the original conversations.

The Cosmiq+ is a budget recreational computer from Deepblu, a dive-tech startup that paired the hardware with its own social dive-logging app. It supports single-gas air and nitrox diving with adjustable PPO2 and conservatism settings, but skips the multi-gas and air-integration features of pricier competitors.
