"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
  • Liquid-filled compass with a 360-degree ratcheting bezel
  • Dive Time Remaining calculated from real-time air consumption
  • Expanded 110-dive log memory
Cons
  • No Bluetooth. Needs a cable to sync with Sherwood's companion app (added in the Wisdom 4)
  • Hose-mounted console, not wireless or watch-style
  • Could not confirm the specific decompression algorithm used
Diver community sentiment
Mixed opinions

Diver sentiment specifically on the Wisdom 3 is thin but leans skeptical. In one Scubaboard thread, an experienced instructor argued against it, calling its algorithm "old" and "very liberal" for repetitive dives with short surface intervals, criticizing console-style computers generally as bulky and prone to snagging on the reef, and steering the poster toward a Shearwater Petrel instead; no one in that thread spoke up in the Wisdom 3's defense. Separately, a Diving Log support-forum thread documents recurring USB/driver headaches getting the Wisdom 3 to sync dive logs to a PC. Broader Sherwood-brand threads praise the console line's large, easy-to-read screen and excellent warranty service.

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

The Wisdom 3 is the previous generation of Sherwood’s flagship console computer, sharing the liquid-filled compass and bold four-line display of the Wisdom 4 but requiring a cable rather than Bluetooth to sync dives to Sherwood’s companion app.
