Pros
  • Liquid-filled compass with 360-degree ratcheting bezel, more precise than typical digital compasses
  • Large, bold four-line display rated highly for readability at depth
  • Dive time remaining calculated from real-time air consumption
Cons
  • Premium price for a hose-mounted console rather than a wireless or watch-style computer
  • Monochrome display only, no color option
  • Same Pelagic DSAT/modified Haldanean algorithm as the older Wisdom 3, not a Bühlmann implementation

The Wisdom 4 is Sherwood’s top-of-the-line console computer, aimed at divers who prefer a mechanical-style liquid-filled compass over a digital one and a large, simple four-line readout over a color screen. It runs on the same Pelagic-built Modified Haldanean/DSAT decompression model as the Wisdom 3 before it, with Bluetooth added for syncing dives to Sherwood’s companion app without a cable.
