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.

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 Research Peregrine is a well-built dive computer designed for recreational and advanced divers who want reliability and simplicity. Its 2.2-inch LCD display provides clear, easy-to-read information underwater, using a straightforward two-button stainless steel interface that’s intuitive and durable. The Peregrine supports Bluetooth connectivity, allowing you to sync dive data with your smartphone easily, which is great for tracking your dives over time.

Battery life is solid, offering about 30 hours on a single charge using medium brightness, and it charges wirelessly via the included USB station—convenient for hassle-free recharging. With a water resistance rating up to 120 meters, it’s suitable for most recreational diving depths and built to withstand tough conditions thanks to its sturdy stainless steel case and silicone band. However, while it has Bluetooth, it lacks GPS and air integration features, which means it does not connect to your tank’s air supply to show remaining air time. This might be a downside if you prefer having that information directly on your wrist.

The device's size and weight are comfortable for extended wear without feeling bulky. The Peregrine balances ease of use with reliable performance, making it a strong choice for divers who want a dependable, no-frills dive computer that handles core functions well but don’t necessarily need advanced features like air integration or GPS.
