We tried the Halcyon Symbios Blue Dive Computer

We put the Halcyon Symbios Blue Handset through real dives—cold-water gloves, wrecks, deco—and tested its trim coaching, air-integrated transmitter, buddy sharing, and best-in-class mobile app for setting gases and gradient factors. See how the 2.4-inch transflective screen, compass, and battery perform underwater, plus the pros and cons (hello, magnetic charger and bungee mount). If you’re progressing into tech—deco, sidemount, or trimix—this review shows what the Symbios Blue does well and who should buy it. Stick around for our giveaway details and link to the full written review with specs and features.
