The Wisdom computer has been one of divings best computers for years. The Wisdom3 is one of the simplest computers to read, large characters and real word that tell you what screen you’re on allow even the newest diver to understand what the computer is telling you. There are no icons that don’t make sense on this computer. The Wisdom3 allows Nitrox or Air diving and can be switched between Imperial (PSI and Feet) and Metric (BAR and Meters). So if you end up somewhere where everyone is diving Metric, it is a quick switch to change. The Quick Disconnect allows you to remove the computer from your hose when not under pressure, a great convenience if you want to bring the computer back to your hotel room after diving to download your dives.
