Pros
  • 3in color touchscreen, the largest and most premium display in Garmin's dive lineup
  • SubWave sonar tech for diver-to-diver messaging underwater, no other brand offers this
  • Up to 60 hours of battery life, T2 tank-pod air integration, CCR support
Cons
  • $1,499 puts it above even the Shearwater Perdix 3
  • Large case size, overkill if you just want a wrist computer
  • Sonar messaging only works diver-to-diver with another SubWave-equipped unit

The X50i is Garmin’s flagship: a 3in color touchscreen, T2 tank-pod wireless air integration, and SubWave sonar for diver-to-diver messaging underwater, a feature no other brand offers. It runs the same Bühlmann ZHL-16C algorithm with adjustable gradient factors as the rest of Garmin’s dive lineup, off a built-in rechargeable lithium-ion battery rated for up to 60 hours of dive time. It’s a large, expensive unit aimed at divers who want Garmin’s full feature set rather than a minimal wrist computer.
