Diver community sentiment
Mixed opinions

Divers on Scubaboard consistently praise the D5's color screen, watch-style form factor, and DM5 app logging, noting it's several hundred dollars cheaper than a Shearwater Teric with a similarly capable feature set. The most recurring and heated complaint is the algorithm's mandatory lockout behavior, up to 48 hours if a diver misses a required deco stop, with no way to disable it, which some experienced divers call a dealbreaker. On r/scuba, owners who dive weekly say the battery (6-12 hours of dive time, needs nightly charging) is a non-issue, while divers doing back-to-back liveaboard days consistently call it a genuine limitation next to 20-30+ hour rechargeables like the newer Suunto Ocean. Several commenters in both places steer new buyers toward Shearwater or Garmin instead, while long-time owners defend it.

The D5 is Suunto’s pitch to divers who want a computer that doesn’t look like a computer. It’s the one people actually keep wearing topside.
