10 Best Diver Computers 2025 in the United States

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 Perdix 2 Ti Dive Computer is designed for divers who want a reliable and advanced tool for their underwater adventures. One of its standout features is the user-replaceable AA battery, which adds convenience and longevity, allowing you to easily swap batteries without the need for specialized tools or services. This dive computer supports air, nitrox, and trimix, making it versatile for both recreational and technical divers. The quick open-circuit (OC) bailout feature from closed-circuit (CC) systems enhances safety, a crucial aspect for serious divers.

The 3-axis, tilt-compensated digital compass is another strong point, aiding navigation underwater, which can be challenging without reference points. In terms of build quality, the Shearwater Perdix 2 Ti is durable, built to withstand the conditions divers face, ensuring it can handle rough and wet environments.

There are a few drawbacks to consider. While the device is lightweight at 13.6 ounces and compact in size, it may still feel bulky for some users, especially during extended dives. The price point might also be a consideration for beginners, as it is typically aimed at serious divers looking for advanced features.
