--- title: "Garmin - Descent Mk3i GPS Dive Smartwatch – 51 mm Fiber-reinforced polymer - Carbon Gray DLC Titanium with Black Silicone Band - (2023) | OzSavers" 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).
