Garmin Descent™ Mk3 and Mk3i Dive Computers
The Garmin Descent™ Mk3 and Mk3i are the successors to the Mk2 series, designed for divers and adventurers. These dive computers offer comprehensive diving functions, including multiple dive modes and the ability to monitor multiple gas mixtures. Plus, they include heart rate tracking, sports modes, and smartwatch features for everyday use.
Released in 2023, the Garmin Descent Mk3 series comes in two versions:
Mk3 (without air integration)
Mk3i (with air integration)
Sizes & Materials:
Mk3: 43mm stainless steel case
Mk3i: Available in 43mm (gold PVD titanium or black DLC titanium) and 51mm (black DLC titanium)
You can also customize your dive computer with interchangeable straps in silicone, nylon, or leather.
Technical Features of the Garmin Descent™ Mk3 Series
Design & Quality
From the moment you unbox the Garmin Descent™ Mk3i, its high-quality construction is evident. The soft silicone wristband ensures a comfortable fit, and since the dive computer arrives pre-charged, you can switch it on immediately.
Display & Usability
✔ AMOLED touch display with adjustable brightness (low, medium, high)
✔ Easy-to-read screen even in direct sunlight
✔ Intuitive touchscreen response (even with a protective film applied)
✔ Customizable settings for language, time zone, and display options
Even without prior experience, setup is quick and hassle-free. The manual is useful for discovering the many functions available.
Battery Life & Charging
USB-C charging (USB cable available separately)
Battery life: Up to 30 hours in dive mode, up to 10 days in smartwatch mode
Energy-saving mode for extended use while traveling
Battery performance depends on factors like brightness settings and usage, but overall, it offers excellent runtime. The exact battery percentage and estimated remaining usage time are displayed on-screen.
Air Integration & Wireless Transmitter
The Garmin Descent™ Mk3i features air integration, allowing you to connect up to eight transmitters.
How does it work?
The transmitter screws into the 1st stage regulator’s high-pressure port.
It then pairs with the dive computer within 5 minutes.
The remaining tank pressure is displayed in real-time, along with air consumption estimates and low-air alerts.
Options:
- Buy the transmitter separately or as a set with the Mk3i
- If you don’t need air integration, choose the Mk3 model
