Suunto has unveiled its next-generation Nautic dive computer at the 2025 DEMA Exhibition in Orlando, Florida. The Nautic will become the new range-topping model, with the smaller, more affordable Nautic S also launched at the event.
Suunto’s full-sized dive computer lineup was beginning to look a little dated compared to some of its rivals. The Eon Core, my daily d(r)iver, and Eon Core Steel were released in 2017 and 2014 respectively. Both are excellent products but are starting to show their age and feel a generation behind competitor Garmin’s current offerings.
Suunto Nautic Features
The most striking feature of the Nautic is its large 3.26-inch full-colour AMOLED display. AMOLED displays, typically used in smartwatches, deliver higher contrast and deeper blacks than older LCD or TFT screens. As far as I’m aware, the Nautic is the first full-sized dive computer to use one.
The Nautic offers a comprehensive suite of diving features, including multigas diving (supporting up to five mixes), sidemount configuration, wireless tank integration, a digital compass, and CCR support, which is expected to arrive via a future software update.
So far, there’s been no official confirmation of the decompression algorithm(s) used in the Nautic, but it’s widely expected to feature the Bühlmann ZH-L16C rather than Suunto’s proprietary Fused RGBM.
Suunto has also included several welcome supporting features. Drawing on its smartwatch expertise, the company has integrated GPS, offline maps, tide and weather data, and a dive planner—a smart move I expect to see more of from major manufacturers in the future.
One small but pleasing detail is that the Nautic is available with an choice of straps—either textile or bungee mount. Many divers prefer bungee mounts, and it’s frustrating when this option requires an additional purchase. So giving us the choice before we buy is a nice touch from Suunto.
Comparisons
Let’s see how the Suunto Nautic stacks up against the competition:
| Shearwater Peregrine TX | Suunto Nautic | Garmin Descent X30 | DYNAMICNORD ADC-80 | |
| Display | Full Colour 2″ LCD | Full Colour 3.26″ AMOLED | Full Colour 2.4″ TFT | Full Colour 2.4″ TFT |
| Gases | Air, Nitrox | Air, Nitrox, Trimix, CCR support (expected) | Air, Nitrox, Trimix | Air, Nitrox |
| Wireless Tank Integration | Yes | Yes | No | No |
| Price | £625.00 | £625.00 | £649.99 | £799.00 |
Final Thoughts
There are clear similarities between the Nautic and Garmin’s range-topping Descent X50i—both have large, wide-aspect displays and are packed with features. However, the Nautic comes in at just £625, less than half the price of its Garmin rival, representing exceptional value.
I’m thoroughly enjoying the ongoing Suunto vs. Garmin battle. It’s a great time for divers, with two highly capable manufacturers going tit-for-tat to pack as much innovation as possible into their devices.
The Suunto Nautic retails at £625.00 and is available now for pre-order with models expected to ship during December 2025.
