The EON Steel was Suunto’s flagship technical computer, built around a fully customizable color display and dual-algorithm support for mixed-gas and CCR diving. It’s since been joined (and partly superseded) by newer Suunto models like the Ocean, but remains a capable option for divers who prioritize display customization.
