Pros
  • Choice of Suunto Fused RGBM 2 or straight Bühlmann GF, unlike the single-algorithm original EON Steel
  • No more dive-ending algorithm lockout after a missed stop, it recalculates instead
  • Fully customizable display layouts carried over from the EON Steel
Cons
  • Rechargeable-only battery, no field-swappable option
  • Bulkier console-style case than watch-style Suunto models
  • Absent from most major retailers' current catalogs even though Suunto still sells it direct, a sign this is an aging model in the lineup

The EON Steel Black is an updated EON Steel with a second selectable decompression algorithm (Bühlmann GF alongside Suunto’s own Fused RGBM 2) and the removal of the old lockout behavior after a violated stop, making it more forgiving for technical and CCR divers who miss a deco obligation mid-dive.
