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

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.
