Garmin Descent G1


You’re a diver underneath with the Descent G1 series. These rugged dive computers are built for multiple types of diving, whether you’re a recreational or technical scuba diver, spear fisher or free diver. The Descent G1 series is enabled with GPS to help mark your surface entry and exit points. Pair with the Garmin Dive™ app to upload, share and review dives, and you can store your favorite dive site locations right on your wrist.

So what makes it stand out from others? The Descent G1 is far more than a just a dive computer. It also doubles as a smartwatch with built-in sports apps and performance tracking features such as VO2 max. Get smart notifications on your wrist, pay for post-dive lunch with Garmin Pay™ contactless payments, and personalize your experience with support from the Connect IQ™ Store. Reach your health goals with wrist-based heart rate, activity and sleep tracking.

  • Track your entry and exit points2 with advanced satellite connectivity.
  • Store and review data for up to 200 dives — and share via the Garmin Dive app1.

  • Use preloaded activity profiles for trail running, swimming, running, biking, hiking, rowing, skiing, golfing and more.
  • This feature uses chronological age, your weekly vigorous activity and resting heart rate to estimate if your body is younger or older than you are. And you can get tips to lower your fitness age.
  • After each workout, recovery time lets you know when you’ll be ready for another hard workout. It even accounts for training intensity and factors such as stress, daily activity and sleep.
  • See conditions — such as tide, wave height, wind and surf rating — for each of the five nearest surf spots, when paired with the Garmin Connect™ app on your compatible smartphone.
  • For training guidance that takes you and your fitness level into account, get daily run suggestions based on your current training load and status.
