The Wisdom computer has been one of divings best computers for years. TheWisdom3 is one of the simplest computers to read, large characters and realword that tell you what screen youre on allow even the newest diver tounderstand what the computer is telling you. There are no icons that dontmake sense on this computer. The Wisdom3 allows Nitrox or Air diving and canbe switched between Imperial (PSI and Feet) and Metric (BAR and Meters). So ifyou end up somewhere where everyone is diving Metric, it is a quick switch tochange. The Quick Disconnect allows you to remove the computer from your hosewhen not under pressure, a great convenience if you want to bring the computerback to your hotel room after diving to download your dives.
