## Overview

The Garmin Descent™ Mk3i is a premium 51mm dive computer and multisport GPS smartwatch 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 communication and tank monitoring, a built-in LED flashlight for low-light conditions, and a dive readiness tool that integrates lifestyle data to enhance dive safety. Beyond diving, it supports comprehensive health and fitness tracking, GPS navigation, and smart notifications, making it the ultimate companion for professional and recreational divers who demand precision, connectivity, and style.

## 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: High-Performance Dive Watch with Unmatched Versatility and Safety Features - I recently took the Mk3i with me to the Philippines for diving, and it exceeded my expectations. The battery life is outstanding, and it performed flawlessly during my SCUBA dives. I paired it with the wireless air pod for my tank, which allowed me to monitor my air supply or track a less experienced diver—an excellent safety feature, even though the pods are a bit pricey. I opted for the larger model with a built-in flashlight, which I initially thought I wouldn’t use but now rely on all the time. The red light mode is especially useful for staying visible when walking on dark streets at night. With so many features packed into this watch, it’s a top-tier dive computer and more. The only small downside is that the buttons can be too easily pressed, but it's not a deal-breaker. If you can invest in it, I highly recommend it for its versatility, durability, and safety-enhancing features.
Review: Informative - The watch is great. Has so many features I’ll probably never use. But the diving portion paired with the t2 was exactly what I was looking for.

The watch is great. Has so many features I’ll probably never use. But the diving portion paired with the t2 was exactly what I was looking for.

### ⭐⭐⭐⭐⭐ Great for groups
*by A***I on August 16, 2025*

Great dive computer. Pros.: GPS; Haptic; Integrated air; Transmitter with no valve; Messages with other divers; Share info with other divers (essential for my, I dive with my family). Cons.: The "sonar" used to communicate does an annoying sound. I prefer my Sheerwater Teric screen customization, maybe I just didn't find the right screen mode. The GPS doesn't automatically input the dive location.
