What We Like

The Eon Steel impresses at first glance, with the large display, substantial weight, and quality construction. The bright display remains crystal clear and easy to read during a dive, and the rechargeable battery means you don’t have to worry about shortened downtimes due to the always-on LED.

The advanced customization features on the Eon Steel are impressive, and regular software updates continue to add new enhancements and refinements. Wireless pairing with the Suunto Tank PODs is fast and convenient.

What We Don’t Like

In designing a dive computer easy enough for newcomers and sophisticated enough for experienced divers, Suunto’s safety measures don’t quite hit the mark for either group. New divers find the many notifications, warnings, and alarms potentially overwhelming and confusing, and experienced divers find them too conservative and potentially limiting of dive times. It’s probable that some of these features are driven by a desire to reduce liability and comply with the strictest of safety standards, but the large number of warnings and alarms, and limited ability to customize them, can be a drawback for some users.

In addition, the tendency of the Suunto to react to an error by returning an error message and locking up for 48 hours offers less flexibility than other products, which will adapt to a failure to switch tanks or missing a deco ceiling by recalculating for current conditions.

Who Should Get the Suunto EON Steel?

The exceptional design and clean display of the Suunto Eon Steel make it easy to use, with a range of advanced features and customization options that make this dive computer powerful enough for even the most advanced divers. The Eon Steel will appeal in particular to technical divers who want advanced data and analysis of their dives. The excellent construction and durability, range of features, and ongoing software updates make the Eon Steel an investment in your dive kit that will last for years to come.

The Eon Steel might be too complicated for newcomers, with features and data that might become confusing or too much to manage. Many new divers don’t want to spend their time buried in a manual; they want to be diving.

Some advanced divers and instructors express frustration with the Suunto algorithm lock logic, finding the ascent calculations to be too conservative and the lockout to be too aggressive. For those who are already familiar with the Suunto RGBM algorithm and welcome its conservative behavior, the Eon Steel is an exceptional dive computer.

Unfortunately, all these technological advances and rich capabilities do come at a price. The Eon Steel is expensive enough to weed out buyers who don’t like the RGBM algorithm and who don’t need these exceptional features. And the fact that it requires updated tank pods that aren’t backward compatible with previous Suunto models is another factor in the price
