Garmin Descent Mk3i 43 mm w/T2 Transceiver: Titanium Dive

Product Overview

The Garmin Descent Mk3i 43 mm w/T2 Transceiver is a premium dive computer and GPS smartwatch designed for serious divers and outdoor adventurers. Built with a titanium case and sized for smaller wrists, it combines rugged dive functionality with everyday smartwatch capabilities. Ideal for recreational, technical scuba diving, and freediving, this device delivers critical dive data, tank monitoring, and underwater navigation in a sleek, durable form. With up to 25 days of battery life in smartwatch mode and a vibrant AMOLED display, it’s engineered for extended use both above and below the surface.

Key Features

• Advanced Dive Computer with AMOLED Display: The 1.2” AMOLED screen offers sharp, high-contrast visuals for easy readability in all conditions, from bright sunlight to deep water. Protected by a scratch-resistant sapphire lens and framed with a 43 mm stainless steel bezel, it balances durability with refined aesthetics.
• Descent T2 Transceiver Integration: Using enhanced SubWave sonar technology, the T2 transceiver enables real-time monitoring of up to eight divers’ tank pressures, air consumption rates, and time remaining—all from your wrist. It also supports preset diver-to-diver messaging within a 30-meter range (with software v.15.70 or later), enhancing safety and coordination during group dives.
• Multi-Band GPS & ABC Sensors: Built-in multi-band GPS delivers precise positioning when you’re on the surface, while integrated ABC (altimeter, barometer, compass) sensors—including an underwater compass—help guide every phase of your dive, from entry to exit. Note that GPS does not function underwater.
• LED Flashlight with Red & White Beams: The built-in LED flashlight features variable intensities and strobe modes, providing reliable illumination in low-light environments. Whether navigating a night dive or signaling a buddy, the red and white light options offer versatility without compromising night vision.
• Dive Readiness Tool: Developed by Garmin, this feature analyzes lifestyle factors like sleep quality, recent exercise, stress levels, and jet lag to estimate your body’s preparedness for diving. While not a medical assessment, it offers actionable insights to help inform safer dive planning.
• DiveView Maps & Dive Logging: Access over 4,000 dive sites with detailed bathymetric depth contours via DiveView maps, helping you locate and orient yourself at popular destinations. The onboard dive log stores data from up to 200 dives, which can be reviewed directly on the device or synced with the Garmin Dive app on your smartphone.
• 200-Meter Dive Rating & Leakproof Buttons: Engineered for serious diving, the case is rated for depths up to 200 meters. Metal inductive buttons are designed to be leakproof and responsive even under pressure, ensuring reliable operation during deep dives.
• Extended Battery Life: Enjoy up to 25 days of battery life in smartwatch mode, reducing the need for frequent charging during extended trips or expeditions.
