Pros
  • Compact, lighter alternative to the EON Steel with the same core dive-planning engine
  • Fully customizable color display and Suunto app integration
  • Supports CCR diving when configured for it
Cons
  • Smaller battery than the EON Steel means shorter time between charges
  • No user-replaceable battery, must charge via USB, plan ahead on multi-day trips
  • Full feature set leans on Suunto's app ecosystem

The EON Core trims the EON Steel’s size and price without touching the underlying algorithm or planning tools, which makes it the better buy for most divers who don’t specifically need the Steel’s bigger battery.
