## Overview

The Garmin Descent Mk3i is a premium 51mm watch-style dive computer featuring a vibrant 1.4” AMOLED display, scratch-resistant sapphire lens, and a robust titanium case rated for 200 meters underwater. It offers advanced SubWave sonar for diver-to-diver messaging and tank monitoring, supports multiple dive modes, and includes a built-in LED flashlight for low-light conditions. With integrated GPS, dive readiness analytics, and comprehensive health and fitness tracking, it’s designed for serious divers who demand precision, connectivity, and style both underwater and on land.

## Description

Discover a deeper connection with the Descent™ Mk3i watch-style dive computer. It features multiple dive modes plus SubWave™ sonar technology for diver-to-diver communication via preset messages (available with software v.15.70 or later). The device also supports monitoring of tank pressures and depth for up to eight networked divers, when paired with the Descent™ T2 transceiver (sold separately). A built-in LED flashlight keeps you going in low-light conditions, above or below water. Purpose-built specifically for divers, the Descent Mk3i dive computer combines a bright 1.4” AMOLED display with scratch-resistant sapphire lens, 200-meter dive-rated case and metal leakproof inductive buttons. DiveView™ maps offer bathymetric depth contours and more than 4,000 dive sites to help you find where to dive and get oriented. Plus, a dive readiness tool, developed by Garmin, shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body’s overall preparedness for diving — so, ultimately, you can make better-informed dive plan decisions (data presented is intended to be a close estimation of metrics tracked). This dive computer is designed to help maximize your preparation for the physical and mental challenges of diving. When you’re ashore, built-in sports apps help you stay on top of your fitness, while Garmin Pay™ contactless payments, music storage and smart notifications keep you connected (compatible smartphone required).

Review: The best of both worlds - The Garmin mk3i 51 mm is my go to watch for fitness training and scuba diving. I've tested the watch for a month. Gym workouts several times a week, and multiple dives to around 85 feet. It's very durable in both. With a minor scratch on the glass. I recommend putting a screen protector on it when you first get the watch. Value for the money? Yes if you are in need of a fitness tracker and dive computer. You get the best of both worlds. 100% yes! Buy this watch if you are very active in and out of the water. You'll never use all it has to offer, but you'll have room to grow and change your outdoor life style.
Review: Worth it - Love this watch so far. Easy to read, loads of good features, works great in the water. Instantly uploaded my dive information to my phone when I got back from my dive.
