Stay focused on your dive, not your gear. The Descent X30’s 2.4” color display is large, sharp, and easy to read underwater. With flip-screen mode, you can orient the display however you like, while four oversized metal buttons ensure effortless navigation — even with gloves on.

Real-Time Metrics to Dive Longer and Smarter

The Descent X30’s NDL Aware depth metrics help extend your dive by showing how changes in depth affect your no-decompression limit in real time. Add in surface interval tracking, dynamic depth charts, and vibration alerts, and you’ll always know exactly where you stand.

  • NDL Aware depth metrics adjust in real time
  • Surface interval tracking for safe multi-dive planning
  • Dynamic depth chart shows where you’ve been and why it matters
  • Audible and vibration alerts keep you informed underwater
  • Water temperature sensor helps identify thermoclines

Advanced Navigation Above and Below the Surface

Never lose your way with the Descent X30’s advanced positioning and navigation tools. Surface GPS with SatIQ marks entry and exit points, while the built-in 3-axis digital compass helps you stay on course below the waves. Pair it with an inReach communicator (sold separately) for SOS capability at the surface.

  • GPS marks entry and exit points automatically
  • 3-axis digital compass for underwater navigation
  • SatIQ delivers precise positioning while conserving battery
  • InReach compatibility for SOS when above the surface
  • Peace of mind whether training, exploring, or diving remote sites

The Descent X30 is built with 100% recycled ocean-bound plastics in its housing and bezel — proof that top-tier performance can also protect the environment. With Garmin Dive app sync, you can automatically upload logs, review past dives, and share your adventures with other divers.

  • Housing and bezel made from recycled ocean-bound plastics
  • Garmin Dive app syncs dive logs automatically
  • Store and review data from every dive on your wrist
