10 Best Diver Computers 2025 in the United States

The Shearwater Peregrine TX is a solid choice for divers looking for a reliable dive computer with advanced features. One of its standout attributes is the 2.2-inch full-color LCD display, which makes reading dive data easy even in challenging underwater conditions. 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 Shearwater Peregrine TX is an excellent dive computer for both beginners and experienced divers alike, especially those who value ease of use and advanced features like air integration and dive data tracking. Its combination of readability, navigation tools, and modern connectivity makes it a great companion for underwater adventures.

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.

The Garmin Descent Mk2i/Descent T1 Bundle is a feature-rich dive computer that stands out with its sleek watch-style design and a generous 1.4-inch color display, making it easy to read underwater and while engaging in other sports. One of its key strengths is the air integration capability with the Descent T1 transmitter, allowing for accurate pressure monitoring on multiple tanks. This feature is invaluable for divers who want to track their air consumption and remaining dive time. In terms of battery life, it offers up to 32 hours in dive mode and an impressive 16 days in smartwatch mode, which is quite competitive in the market.

The device supports advanced features like wrist-based heart rate monitoring and Pulse Ox for tracking blood oxygen levels, beneficial for those wanting to keep an eye on their health during dives and altitude activities. Moreover, it includes support for various sports apps, Garmin Pay, and music storage, appealing to users who enjoy multi-sport activities.

While the Garmin Descent Mk2i is feature-packed, it may feel overwhelming for beginners who are new to diving computers. The reliance on a dedicated app for reviewing dive logs might also be a downside for those who prefer a more straightforward, on-device review. Additionally, although it's rugged, the price point could be on the higher side for casual divers who may not need all the advanced features it offers. The Descent Mk2i/Descent T1 Bundle is a strong option for serious divers or those who engage in multiple sports, providing a wealth of features and robust performance.
