The battery life is solid, offering up to 30 hours of diving on a single wireless recharge, which is convenient and reduces downtime. Bluetooth connectivity to Shearwater Cloud allows divers to track and review their dives easily.

While the dive computer uses plastic for its casing, which might feel less durable compared to metal-bodied models, it offers strong core features. Some advanced technical divers might find it lacks the depth of customization or multi-gas support available in higher-end models. This dive computer is an excellent choice for recreational divers who want reliable air integration, a clear display, and easy access to dive data without complexity.

The Garmin Descent Mk3i is a high-end, versatile dive computer that doubles as a multisport GPS smartwatch.

The device also boasts a robust build with a scratch-resistant sapphire lens and a titanium bezel, which adds to its durability and aesthetic appeal. With its comprehensive dive modes and 200-meter water resistance, it is suitable for both recreational and technical divers, including freedivers.

The air integration capability, when paired with the Descent T2 transceiver (sold separately), allows for monitoring tank pressures and exchanging messages between divers, enhancing safety and communication underwater. The built-in LED flashlight with variable intensities is particularly useful in low-light environments, providing both red and white light options. Additionally, the dive readiness tool is a thoughtful feature, offering insights into how lifestyle factors may impact diving performance. The inclusion of DiveView maps and multi-band GPS technology further enriches the diving experience by offering detailed dive site maps and precise navigation.

For fitness enthusiasts, the device supports various sports apps and provides extensive health monitoring, including heart rate and sleep tracking. On the downside, the device is relatively heavy at 105.6 grams, which might be noticeable on the wrist during extended use. Furthermore, certain advanced features require additional purchases, such as the Descent T2 transceiver for full air integration functionality. Connectivity options include Bluetooth and USB, ensuring compatibility with both Android and iOS devices. The battery life is powered by a lithium polymer battery, though the 150mAh capacity may require frequent charging, especially with intensive use. Despite these minor drawbacks, the Garmin Descent Mk3i offers a comprehensive package for divers seeking a reliable and feature-rich dive computer that also supports an active lifestyle.

The integration with the Bühlmann 16 GF algorithm and wireless tank pressure monitoring enhances safety by providing real-time updates on tank pressure and gas consumption.

The dual-band GNSS and global offline maps ensure accurate route tracking above water and the ability to save and share 3D dive routes, adding an element of adventure and post-dive analysis. The SUUNTO Ocean also doubles as a comprehensive sports watch with over 95 preset modes and AI coaching, catering to fitness enthusiasts beyond diving. However, it is slightly on the heavier side, weighing 3.49 ounces, which might be a consideration for some users. The battery life is impressive, offering up to 40 hours in dive mode and up to 26 days on standby, with fast charging capabilities to minimize downtime.

Connectivity is robust with Bluetooth support, allowing sync with the Suunto app for enhanced functionality.
