Garmin - Descent Mk3i 51mm Carbon Gray and Black Band Dive Computer Bundle - Black - (2025)

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).

Designed for life in the world of flight, D2 Mach 2 is the most highly evolved Garmin aviator smartwatch to date. It combines classic styling with a bright AMOLED touchscreen display, advanced flight mapping, voice commands and a powerful built-in LED flashlight — plus health and fitness features to help pilots perform at their best.
