Scubapro

Scubapro G2 Tek

The G2's case and screen, retuned for technical diving with a straight gradient-factor algorithm.

Open BLE sync (libdivecomputer)

Syncs wirelessly with third-party apps (Subsurface, Currents, etc.), not just the manufacturer app.

"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
  • Straight ZH-L16 GF algorithm instead of Scubapro's adaptive ADT model, for divers who want direct gradient-factor control
  • Rechargeable battery good for up to 50 hours per charge
  • Full tilt digital compass and Scuba/Freediving/Gauge/CCR/Sidemount modes
Cons
  • 120m depth rating is shallower than the standard G2's 200m
  • Optional hoseless air integration transmitter sold separately
  • Rechargeable battery means planning around charging on multi-day trips
Diver community sentiment
Mixed opinions

Scubaboard discussion specific to the G2 Tek is fairly thin and centers mostly on whether existing G2 owners should upgrade, with skepticism that Scubapro would offer a firmware-only upgrade path rather than requiring a new purchase, since the Tek shares the G2's hardware. Broader sentiment about that shared platform is mixed: owners report years of reliable service and like the bright, easy-to-read screen, but there's a recurring complaint thread about the wireless air-integration transmitter losing signal or failing to stay paired once submerged, in at least one case traced to a hardware defect requiring warranty replacement. Some divers also find the menu system needlessly complex next to competitors like Shearwater.

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

The G2 Tek takes the G2’s full-color case and display and swaps in a straight ZH-L16 GF algorithm in place of Scubapro’s adaptive ADT model, aimed at technical divers who want direct control over gradient factors rather than Scubapro’s proprietary tuning.
