10 Best Dive Computers 2026 in the United States

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. The dive algorithm supports multiple modes, from recreational to technical diving and freediving, making it versatile. Battery life is solid for a dive watch, powered by a rechargeable lithium polymer cell, balancing usage time and compact size. Connectivity options include Bluetooth and USB, enabling easy syncing with Garmin's Dive app to review logs, share data, and explore dive sites with bathymetric maps. GPS and ABC sensors assist surface navigation and underwater orientation, though GPS doesn’t work underwater, which is standard for dive computers.

Beyond diving, it doubles as a multisport smartwatch with health monitoring, notifications, music storage, and Garmin Pay, making it practical for everyday use. The advanced air integration requiring an additional accessory adds cost and complexity, and while the screen is beautiful, some users may find the 1.2-inch size small if they prefer larger displays. This device suits serious divers seeking a reliable, feature-rich computer that also functions well outside the water.

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 Shearwater Perdix 2 Ti is a high-quality dive computer designed for serious divers who want reliable and clear data underwater. Its vibrant 2.2-inch LCD with LED backlight and sharp resolution makes it easy to read even in low light or murky conditions, which enhances safety and convenience. Battery options are flexible, supporting various types including rechargeable and standard AA batteries, offering between 40 to 100 hours of dive time depending on the battery used. This flexibility benefits extended dive trips or travel. The computer supports a wide range of gas mixes, allowing up to 5 open circuit and 5 closed circuit gases, ideal for technical divers needing complex gas switching. It logs a substantial amount of dive data (up to 1,000 hours), helping divers review and plan future dives effectively.

The Perdix 2 Ti is built tough, featuring a strong glass lens and a depth rating of 260 meters, enabling it to handle deep and challenging dives safely. Its size and weight are moderate—roughly 4.5 by 4 by 2.75 inches and weighing under 0.4 kg—which might feel a bit bulky compared to slimmer models but is reasonable given its feature set. While air integration capability is not mentioned, divers looking for direct tank pressure sensor connection should verify this aspect further. The Perdix 2 Ti excels in clarity, gas versatility, battery life, and ruggedness, making it well suited for technical and deep divers who prioritize reliability and detailed dive information.
