## Overview

The Garmin Descent™ Mk3i is a premium 43mm watch-style dive computer featuring a bright 1.2” AMOLED display, scratch-resistant sapphire lens, and a durable titanium case rated for 200 meters underwater. It offers advanced SubWave sonar for diver communication and tank monitoring, multi-band GPS for precise surface navigation, and a unique dive readiness tool that integrates lifestyle data to enhance dive safety. Beyond diving, it functions as a full-featured smartwatch with fitness tracking, music storage, Garmin Pay, and smart notifications, backed by up to 10 days of battery life in smartwatch mode.

## 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). Purpose-built specifically for divers, the Descent Mk3i dive computer combines a bright 1.2” 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. You can also reference ABC sensors with a 3-axis underwater compass as well as surface GPS capabilities to mark your entry and exit points. 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).
