This is particularly useful for divers who prefer clear visuals while navigating. Additionally, the optional wireless air integration with the Shearwater Swift Transmitter provides real-time gas pressure data, helping divers manage their air supply more accurately during dives.

The inclusion of a tilt-compensated digital compass is a great bonus, ensuring you can maintain your heading underwater, which is essential for navigation. The rechargeable battery is another strong point, offering up to 30 hours of diving time, allowing for extended dive trips without worrying about battery life. The Bluetooth connectivity to Shearwater Cloud for tracking dive data adds a modern touch, making it convenient to log and review your dives.

The Garmin Descent Mk3i is a dive computer designed for divers who want advanced features in a compact, watch-style device. Its bright 1.2-inch AMOLED screen with a scratch-resistant sapphire lens makes it easy to read underwater, and the 43 mm stainless steel bezel is both durable and stylish. It supports air integration, allowing you to monitor your tank pressures directly on the watch when paired with the optional Descent T2 transmitter, which is a big plus for safety and group dives. The built-in dive algorithms cover a wide range of diving types, from recreational to technical and freediving, making it versatile for different skill levels. This model also includes an innovative dive readiness tool that considers your sleep, stress, and exercise to help you plan safer dives.

For navigation, it offers multi-band GPS and an underwater compass, though GPS itself doesn't work underwater. Connectivity is strong with Bluetooth and USB support, syncing dive logs and health data to the Garmin Dive app for easy tracking and sharing. The battery life is reasonable for a device with so many features, powered by a rechargeable lithium polymer battery. At just over 2 ounces and sized for smaller wrists, it’s comfortable for daily wear. Alongside diving, it includes general fitness and wellness monitoring, plus smartwatch features like music storage, notifications, and contactless payments.

The Descent Mk3i can be pricey and requires the extra purchase of the T2 transmitter for full air integration benefits. Additionally, some advanced features may have a learning curve, especially for those new to dive computers. This device represents a high-quality, durable, and feature-rich dive computer that also functions effectively as a smartwatch.

The Garmin Descent Mk3i is a high-end dive computer designed like a smartwatch, making it comfortable and stylish for everyday wear, especially for those with smaller wrists due to its 43 mm size. Its standout feature is a bright, sharp 1.2-inch AMOLED display protected by a scratch-resistant sapphire lens, ensuring clear readability underwater and durability. Air integration is robust with the included Descent T2 transceiver, allowing you to monitor tank pressures and communicate with up to eight divers within 10 meters, which is a rare and valuable feature for group diving. The dive algorithm supports multiple modes from recreational to technical diving and freediving, providing versatility for various diving styles.

Battery life can last up to 25 days in smartwatch mode and around 30 hours during active diving, which should cover most dive trips without frequent charging. The watch also offers GPS and ABC sensors (altimeter, barometer, compass) for surface navigation, but keep in mind GPS doesn’t work underwater. Its user interface is advanced but user-friendly, with metal buttons designed to prevent leaks and a touchscreen for ease of use on land. Durability is solid thanks to its titanium construction and 200-meter water resistance, plus a built-in LED flashlight for low-light conditions.

One minor drawback is its weight (about 1.5 pounds) which might feel a bit heavy compared to simpler dive computers. Also, the price and feature set make it best suited for serious recreational and technical divers rather than beginners looking for a basic model. The Garmin Descent Mk3i blends advanced dive features with smartwatch capabilities and rugged build quality, making it a great choice for divers who want comprehensive data and connectivity in a sleek package.
