Pros
  • Diver-replaceable battery with hot-swap capability, rated for 300 hours
  • 22% larger digits than the previous Pro Plus 3
  • Bluetooth sync to Oceanic's companion app despite being a traditional hose-mounted console
Cons
  • Digital compass is a separate add-on version, not standard
  • Traditional hose-mounted console design, bulkier than wrist computers
  • Retailer listings suggest it's being phased out in favor of the newer Pro Plus X

The Pro Plus 4.0 is Oceanic’s traditional hose-mounted console computer, built around large, high-contrast digits rather than a compact wrist form factor. Some retailers now list a successor, the Pro Plus X, suggesting this model is nearing the end of its run.
