There’s one bit of kit that every diver needs dialled in perfectly to their needs: a dive computer. Whether you’re a beginner diver or a seasoned technical diver, your computer is your essential underwater guide, tracking depth, time, gas consumption and decompression. Tracking this information both keeps you safe and helps you get the most out of your time in the water, so your dive computer must be reliable, readable, and responsive to the way you dive.
With that in mind, we’ve spent time in the water with the latest models to help guide you towards the best dive computers available in 2025. These are the models we trust, use, and recommend, including basic watch-style computers to high-powered units with full air integration and compatibility with tech setups.
If you’re shopping for the best dive computer this year, you should find the perfect fit from our hand-picked favourites listed below.
Suunto Ocean
As Suunto’s most exciting release in years, the Suunto Ocean is incredibly deserving of its place on our best dive computers list. Designed as a true crossover between a dive computer and an outdoor sports watch, the Ocean nails it for anybody who dives as part of a wider active lifestyle. On a diving front, it supports multiple dive modes and connects wirelessly to the Suunto Tank POD for air integration.
What we especially love is the bright AMOLED display, which is genuinely readable in all light conditions, along with an intuitive interface tailored towards easy navigation. The other sport modes are easily accessible and just as feature-rich, making this the best dive computer for anybody who wants a gadget that can adapt to their lifestyle and do so in a reliable but stylish way.
Garmin Descent Mk3i
Rivalling the Suunto Ocean on the dive computer crossed sports watch front is the Garmin Descent Mk3i - a dive computer that can do pretty much anything. The MK3I is one of the most advanced dive computers available right now, supporting up to 8 wireless tank integrations, multiple dive modes, and diver-to-diver sonar-based messaging.
Above water, it’s a fully-fledged smartwatch, GPS tracker, and performance coach, but this versatility and the high-performance aspects aren’t included at the expense of more everyday functionality. Neat inclusions like the built-in dive compass and integrated flashlight show that Garmin has been incredibly thoughtful with real scenario consideration. The result is a dive computer that delivers truly cutting-edge functionality without overpromising.
Scubapro Luna 2.0
If clean design, crisp readability and easy use are top of your priority list, it’s a more recreational and traditional dive computer that should be high on your radar. The Scubapro Luna 2.0 is one of the very best dive computers in this category, offering simplicity without losing performance.
The full-colour display of the Luna is large and uncluttered, with adjustable brightness and intuitive menu navigation. It supports air, nitrox and gauge modes as standard, and while air integration is not built-in, it pairs seamlessly with Scubapro’s Smart+ Pro transmitter. The soft, silicone strap is comfortable to wear, encapsulating the fact that the Luna 2.0 is perfect for those who want to travel light with a fuss-free computer they can rely on.
Suunto D5
More of an out-and-out dive computer than the similar looking Suunto Ocean, the Suunto D5 is the brand’s latest mid-price option. This is undoubtedly one of the best dive computers for divers who want a watch-style unit without paying a premium price. It still packs all of the features you’d expect and need, including air integration compatibility and an inbuilt compass. What we really like about this dive computer, though, is the customisable dive fields which allow you to fully fine-tune your set-up.
On a stylistic note, the D5 is fully customisable, too. There is a range of different strap colours and texture options available, along with extensions for drysuit or thicker wetsuit compatibility. Plus, Suunto’s intuitive app integration makes post-dive analysis and logbook syncing a breeze. The D5 is a true all-rounder.
Suunto Vyper Novo
The Suunto Vyper Novo has earned a reputation as one of the most robust dive computers out there. While it displays a fuss-free, simplistic design, the features are far from it, and this is often the dive computer we recommend to those who want serious capability without having to spend big on a watch with extra, non-dive-related functionality.
The large dot matrix screen of the Vyper Novo is crystal clear underwater, and the button navigation is easy to use even with thick gloves. This dive computer also supports air, nitrox, gauge, and free dive modes, and also features air integration, a digital compass, and a dive simulator for planning. It’s a real workhorse and a great upgrade if you’ve outgrown a more basic dive computer.
Final Tips For Choosing Your Dive Computer
When choosing a dive computer, the best place to start is always by thinking about how you dive and what features genuinely matter to you. Whether that’s easy readability, air integration, or just a comfortable watch that works for daily wear too, the right dive computer is out there. As divers, we’d be happy to use any of the dive computers outlined on this list, so you should feel confident that whichever you pick will serve you well.
