"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

Best-in-class sunlight-readable display for the price
Simple, uncluttered interface, easy for divers new to computers with real dive planning
Shearwater's Bluetooth desktop/mobile app for logs and firmware updates

Cons

No built-in digital compass
Single gas only, no multi-gas switching for tec or staged decompression
No wireless air integration on the base model (see Peregrine TX for that)

Diver community sentiment

Mostly positive

Divers on Scubaboard and r/scuba consistently praise the Peregrine's bright, easy-to-read display, simple two-button interface, and the tissue-loading graphic that helps recreational divers visualize decompression status. Shearwater's firmware quality and warranty reputation come up repeatedly, and the roughly week-long battery life between charges is called a major convenience. On a large r/scuba buying-advice thread, dozens of commenters recommended it over a same-priced Suunto D5 almost unanimously, citing Suunto's deco-lockout behavior; one reply noted they'd "yet to see one bad review about the Peregrine." The main complaint is the lack of built-in air integration on the base model, though most say they can live without it or step up to the Peregrine TX.

The Peregrine is Shearwater’s answer to “I want a real dive computer, not a toy, but I’m not doing decompression dives.” It borrows the same display and firmware lineage as the Perdix, stripped down to a single-gas recreational computer.
