Intuitive menus and a simple 3-button layout make Suunto EON Steel Black very easy to use despite the many options available.
Equipped with two dive algorithms, Suunto Fused RGBM 2and Buhlmann 16 GF and configurable ascent profiles, you decide what is your decompression profile for today's dive.
Designed For Years To Come
Suunto EON Steel Black comes with a stylish brushed stainless steel bezel and a vivid high contrast color screen — easy to read even in low light conditions. The long-lasting battery endures even the toughest diving conditions, and with a full charge, provides up to 40 hours of diving.
Put to the test in the toughest diving conditions by Suunto's internal dive team on hundreds of dives — the Steel Black is functional, accurate, and built to take a beating. The reusable storage case and user updatable software, Suunto EON Steel Black is your trusted diving companion for years to come.
Transfer your dive logs easily over Bluetooth to your mobile phone. With the Suunto app you can relive, and share your diving adventures, build an all-inclusive dive history by enriching your dive logs with photos, comments and dive location. Review and analyse your dive data including dive time, maximum depth, device settings, gas consumption (when using Suunto Tank POD).
Follow your pressure conveniently straight from your wrist. Get tank pressure on your display wirelessly by pairing your Suunto EON Steel Black with a Suunto Tank POD before diving. You can connect up to twenty PODs. For computer and POD complete.
The Suunto EON Steel Black's main priority is diver control and usability. It all starts with full user customisation. Suunto claims that this computer will grow with you as your diving and skills evolve. The Suunto EON custom colour display assures that. You can choose between classic and graphical viewing and define exactly what you want to be displayed all within four custom user displays. The EON is also setup to receive customisable add-on skins and comes with a wrist strap and bungee option for whatever works best for you.
Within your custom-set interface you can cycle between features such as: multi-gas diving (up to 20 gases) with air/nitrox/trimix support, integrated tilt-compensated 3D compass, altitude adjustment, alarms/stops, decompression data, gauge/bottom timer mode, timer, depth alarms, and air integration options.
Suunto updatable software will save you big bucks in the long run. Instead of buying model after model, year after year, you can download and update your EON with new software (such as closed-circuit rebreather). Suunto DM5 software allows you to plan out your dives in advance and then seamlessly transfer your data to your computer. The easy to use 3-button interface is accessible even with the thickest cold water diving gloves. Additionally, the brilliantly bright colour display that can be read at any angle plus the simple 3-button interface makes this computer incredibly simple and usable at any level of diving for new and advanced users.
Designed To Be Tough
The Suunto EON Steel Black's construction is no less impressive. The housing makes use of extremely rugged reinforced composite with over 50% of that being strong glass fibre. The bezel is constructed with brushed stainless steel that will handle years of abuse. Plus, the highly durable and resistant Xensation glass screen will withstand rugged use time after time.
The Suunto EON Steel Black is guaranteed to 150 metres (492 feet), has an operational temperature range of 0 Degree C to +40 Degree C (+32 Degree F to +104 Degree F) and has been tested and tested again for all types of diving. Additionally, the new rechargeable battery will last 20–40 hours of dive time on a full charge and can be charged when connected to a computer or with a Suunto charger.
The Suunto EON Steel Black is quite literally the greatest dive computer available today. It is extremely versatile, technologically advanced, user friendly, fully customisable, rugged, and usable by any level of diver in any diving situation. The EON Steel Black is an investment that will pay you back again and again with its updatable software and durable construction. Make the switch to one of the most advanced computers on the market today.
Computer comes with a USB cable, quick guide, safety and regulatory leaflet, protective boot, display scratch guard, bungee adapter, extra strap loop and Suunto sticker.

The Suunto EON Steel Black is also available
bundled with a Tank Pod. What We Think...
The multiple award-winning Suunto EON Steel Black is, as advertised, a computer that grows with you. The large, clear colour display is great for divers who struggle to read smaller dive computer displays. It's perfectly suited for the entry-level diver with its sleek, intuitive, compact and lightweight design, but those who dive once a year and have no intention of progressing further may find the Suunto Zoop Novo more suited to their budget.
For the more active recreational diver going beyond basic recreational requirements, the digital 3D compass and support for multiple tank pods make this a great solution. For divers who think they might develop into technical diving, the Suunto EON Steel Black is a worthwhile investment, allowing the possibility of up to twenty Air, Nitrox and Trimix gas mixes, plus CCR diving as they acquire the relevant skills.
We know some people dislike the Suunto Fused RGBM model for being 'too conservative', however, we believe conservatism in recreational diving is the order of the day. Dedicated techies may prefer the Bühlmann-based algorithms to squeeze in those extra few minutes of dive time, but pushing limits is not on our list of things to do. Besides, you can change the settings and make the Suunto EON Steel Black's Fused RGBM model more or less conservative as you wish. Or you can switch to the Buhlmann 16 GF model with configurable ascent profiles. You decide what's your decompression profile for the dive.
Confused about Decompression Algorithms?
There is a lot of talk about the benefits and problems associated with various diving decompression algorithms. In this video, Dr. Bruce Wienke, the respected creator of the decompression software used in the Suunto dive computers and many other brands, discusses the key differences between Suunto's Fused RGBM and the open-source Buhlmann GF model.
There are people who criticise the Suunto Fused RGBM model saying it forces them to spend extra time in the water compared to a dive computer using the Buhlmann GF model. Not so. You can adjust the conservatism of the Suunto software. Make it more aggressive for less time decompressing, or even more conservative. The choice is yours.
There are people who complain that the Deep Stops feature of the Suunto software holds them up when diving with buddies whose dive computers don't support deep stops. Then turn it off. Deep Stops are an optional setting. You don't have to do them.
In a recent test, a boatload of technical and rebreather divers with dive computers using the Buhlmann GF model were given Suunto Eon Core dive computers to take on their long deco dives. They all said that they wouldn't wait for the Suunto, that they'd dive as their own Buhlmann GF model dive computer told them to. Based on the myths they had heard, some divers said that this would mean that they'd thus be locking the Suunto EON Core out and that the EON Cores wouldn't be able to be used the next day.
Well the settings of each Suunto EON Core was adjusted to match the aggressiveness or conservatism of the Buhlmann GF settings each diver was using. Dives completed and back on the boat, not one Suunto EON Core had locked out. Every Suunto EON Core had closely matched the other dive computer throughout the dive. Myth busted!
We sell dive computers that use the Buhlmann GF model, and ones that use the Suunto Fused RGBM model. Take your pick. Just don't base your pick on the misinformation and myths that are out there about these diving algorithms.
