We tested the Suunto Eon Core dive computer. With a spacious color screen , simple 3-button control and air integration, it was a Testers choice for wrist computers. See full ScubaLab dive computer review here.

We tested it at the University of Southern California Hyperbaric Chamber on Catalina Island. We also tested it in the field at Blue Grotto Dive Resort in Central Florida. We put through a series of simulated dives alongside other computers to gauge the performance of its decompression algorithm. We also simulated dives with rapid ascents and missed deco stops to assess the effectiveness of its alerts and warnings. We evaluated how easy it was to set up and use, how well we could see the screen in different conditions, and how well it presented important data during our dive.

The Eon Core shares many display and operating elements with Suunto's Eon Steel, but the Core is much lighter and more compact, although the screen is just as large. Divers rated the Eon Core very good for intuitive operation, with logical button functions and crystal-clear menu prompts. They scored the Core’s readability excellent underwater, where the vibrant colors stand out on the black background. “Perfect!” one diver called the underwater view, though reading at the surface in bright sun required a bit of shading. Divers also liked what they saw on the screen, giving the Core the tying top score for selection, layout and presentation of dive data. It also took top score for its on-board log, with a graphic display you can toggle through a dive minute-by-minute to see info including depth and gas consumption. The Core’s overall size is surprisingly compact relative to the big display (which can be flipped for right-arm wear), helping the Core take a very good score for ergonomics. Sophisticated and simple, and a favorite of test divers, the Eon Core is a Testers Choice for wrist mount computers.
