"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
  • Monitors up to 6 wireless transmitters simultaneously
  • Digital compass with GPS for surface navigation between preset waypoints
  • Induction or cable charging, plus a plug-in O2 analyzer for setting gas mixes directly on the computer
Cons
  • First-generation computer from a brand better known for regulators
  • Premium price for a 100m depth rating
  • Sidemount and CCR modes are wasted if you only dive single-tank recreational
Diver community sentiment
Mixed opinions

Divers on Scubaboard generally view the DSX as a reasonably capable technical computer (color display, sidemount/CCR modes, gas switching) positioned as a lower-cost alternative to Shearwater, but reliability and support have been recurring sore points. Multiple threads describe firmware update failures in the Diverlog+ companion app, at least one report of a "System Error 10" lockup where the computer froze mid-ascent while hunting for a lost transmitter signal, and repeated complaints of slow Apeks/Aqualung customer service (especially in the US). Apeks did issue replacement units and acknowledge the error-10 bug, and a firmware update resolved some communication issues, but overall sentiment is that the DSX is promising on paper yet still "proving itself" against established competitors.

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

The DSX is Apeks’s first computer built entirely in-house, aimed at technical divers who want sidemount and CCR modes, six-transmitter gas monitoring, and a built-in GPS-assisted compass in one wrist unit.
