## Overview

The Garmin Descent Mk3i is a premium 51mm titanium dive computer featuring a vibrant 1.4” AMOLED display, 200-meter water resistance, and advanced SubWave sonar for diver communication. With up to 25 days of battery life, multi-band GPS, and a dive readiness tool that factors in your lifestyle metrics, it’s engineered for serious divers who demand precision, durability, and connectivity 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: Great in many ways. - My first time wearing a smart watch or any watch for that matter. Regular diver and out in the open waters often, the GPS features are very good. Can't find any faults with dive computer either. It's quite expensive but the build quality and features are definitely worth it.
Review: Amazing watch - This is probably the best watch I've ever owned. It allows me to monitor so many things that I look for in a watch plus more.

### ⭐ Useless power bank is a scam
*by K***R on March 23, 2025*

The Garmin Descent is great- the rating is for the Wearable4U battery, which is why I ordered from this listing rather than direct from a manufacturer. It charges my Samsung S24 about 20-25% before becoming a paperweight. Actually put me in danger the first time I tried to use it cause I was left in a strange city with a dead phone trying to remember how to get home. Just buy direct from Garmin.
