10 Best Dive Computers 2026 in the United States

The Shearwater Peregrine TX is an excellent choice for divers seeking a reliable and feature-rich dive computer. Its standout feature is the large, full-color 2.2-inch LCD display, which makes it easy to read underwater, even in varying lighting conditions. With the option for wireless air integration, it provides real-time gas pressure data, enabling divers to manage their air supply effectively and make informed decisions during their dives. The included tilt-compensated digital compass is a great asset for navigation, ensuring divers stay oriented throughout their underwater explorations.

One of the highlights of the Peregrine TX is its rechargeable battery, which lasts up to 30 hours, allowing for extended diving without the hassle of changing batteries. Additionally, the Bluetooth connectivity to Shearwater Cloud enhances the user experience by allowing divers to track and analyze their dive logs conveniently.

There are a few drawbacks to consider. The weight of 16 ounces may feel a bit heavy for some users, especially if they prefer lightweight gear. The plastic material, while durable, might not appeal to those looking for a high-end, premium feel in their equipment. Also, the price point could be a consideration for casual divers, as it may be on the higher side compared to more basic models. The Shearwater Peregrine TX stands out as particularly suitable for serious divers or those who frequently dive in varying conditions, thanks to its comprehensive features and user-friendly design. Casual divers may find it more advanced than their needs require, but its capabilities certainly justify its standing in the digital diving gauge category.

The Garmin Descent Mk3i is a high-end dive computer designed for divers who want a compact, watch-style device with advanced features. Its 1.2-inch AMOLED display is sharp and vibrant, easily readable underwater, complemented by a durable sapphire lens to resist scratches. Sized for smaller wrists at just 68 grams and 43 mm bezel diameter, it offers comfort without bulk.

One of its standout features is the air integration via the Descent T2 transmitter (sold separately), allowing real-time tank pressure monitoring for up to eight divers and diver-to-diver messaging up to 30 meters, which is excellent for group diving.

Beyond diving, it doubles as a multisport smartwatch with health monitoring, notifications, music storage, and Garmin Pay, making it practical for everyday use.
