"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

Titanium construction with an armored casing built for daily technical/CCR use
1.5V lithium AA battery still user-replaceable, up to 60 hours, no charging cable required
6x faster Bluetooth than Perdix 2 for quicker log downloads and firmware updates

Cons

$1,295 puts it well above the Perdix 2 and most of the field
Full-size case, not a watch-style computer for casual recreational diving
Trimix, CCR, and multi-gas features are wasted if you only dive single-tank recreational

Diver community sentiment

Mixed opinions

Most verifiable diver discussion so soon after launch is concentrated in one active Scubaboard thread. Early owners praise the AMOLED screen as a genuinely crisp upgrade over the Perdix 2, appreciate more flexible field/layout customization, and describe the firmware changes as "all straight positives," including improved third-party dive-log compatibility. More critical voices frame the Perdix 3 as an incremental refresh rather than a true generational leap, one poster calling it closer to a "Perdix 2 Pro," arguing Shearwater is playing catch-up to Garmin's AMOLED display and longer wireless transmitter range. There are also scattered complaints about alleged declining build/QC and Perdix 2 resale-value concerns.

Scubaboard: Perdix 3 just dropped Shearwater: official Perdix 3 product page

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

The Perdix 3 replaces the transflective monochrome display that defined the Perdix line since 2015 with a full-color AMOLED screen, while keeping the AA-battery design tec divers relied on. It’s Shearwater’s new flagship, sitting above the Perdix 2 rather than replacing it outright.
