10 Best Diver Computers 2025 in the United States

The Garmin Descent™ Mk3i is a highly capable dive computer that stands out with its quality features and versatility. Its 1.4” AMOLED display is easy to read, and the scratch-resistant sapphire lens ensures durability, making it suitable for various diving conditions. With a depth rating of 200 meters and multiple dive modes, it's designed for both recreational and technical divers, which is a strong point for those looking for a comprehensive diving tool.

One of its notable features is the advanced SubWave sonar technology that allows for diver-to-diver communication, which can be extremely helpful during group dives. The built-in LED flashlight adds an extra layer of safety, especially in low-light situations. Additionally, the integrated health monitoring tools and sports apps cater to users who want to track their fitness levels alongside their diving activities.

While it has many strengths, there are a few drawbacks to consider. The need for a separate Descent T2 transceiver for full functionality with tank pressure monitoring may be off-putting for some users who prefer an all-in-one solution. The size and weight, while manageable at 105.6 grams, may feel bulky to users accustomed to simpler dive watches. Furthermore, while the dive log feature is an excellent way to keep track of dives, it may lack some advanced analytics that dedicated dive log software could provide.

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 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.
