The Suunto EON Steel Black is a full-featured dive computer built for technical and recreational divers who want reliable, customizable performance at depth. Running on the Suunto Fused RGBM 2 algorithm with support for Air, Nitrox, Trimix, and CCR modes, it covers everything from warm-water reef dives to demanding technical profiles in a clean, wrist-mounted package.
Product Overview
At the heart of the EON Steel Black is a large, vivid color display set in a stainless steel case with a composite bezel. The display layout is fully customizable per dive mode, so you can prioritize the data fields that matter most for the profile you're running. With a 150m (492ft) depth rating and support for multiple simultaneous gas mixes, the computer handles everything from sport diving to structured technical profiles.
Wireless air integration via the Suunto Tank Pod allows pressure monitoring for up to 10 transmitters simultaneously, giving multi-tank and rebreather divers a clear readout of gas supply without hoses. The Suunto Fused RGBM 2 decompression model accounts for microbubble load, providing a physiologically informed ascent calculation that tends toward conservatism.
Built-in digital compass, dive alarms, and Bluetooth connectivity to the Suunto app complete the package. Whether you're logging recreational ocean dives or managing complex technical configurations, the EON Steel Black adapts to the dive and stores detailed log data for post-dive analysis.
Suunto Fused RGBM 2: Decompression You Can Trust
Not all decompression algorithms are equal. The Suunto Fused RGBM 2 model builds on the original RGBM algorithm by accounting for microbubble formation throughout the ascent, not just at decompression ceilings. The result is a more conservative and physiologically grounded ascent profile that factors in your recent dive history across repetitive dives. For technical divers pushing planned limits, and for recreational divers who want a meaningful safety margin, this is a real differentiator over simpler table-based models.
Wireless Air Integration for Up to 10 Tanks
The EON Steel Black connects wirelessly to the Suunto Tank Pod, eliminating high-pressure hoses from your configuration. With support for up to 10 simultaneous transmitters, the computer is well suited for multi-stage technical dives, sidemount setups, and CCR divers monitoring both primary and bailout cylinders. Tank pressure, air time remaining, and bar or psi readouts appear directly on your customizable dive screen, keeping critical gas information front and center at every stage of the dive.
Customizable Display Built for How You Dive
Every diver prioritizes different information. The EON Steel Black lets you customize the display layout independently for each dive mode, choosing which data fields appear on screen and how they are arranged. Whether you need a clean two-field view for recreational dives or a dense data layout for a technical profile with multiple gases and decompression stops, the display adapts. The large, vivid color LCD remains readable in low light, at depth, and in reduced-visibility conditions.
