A dive computer is a tool you will come to rely on during your adventures. It provides many critical features such as depth gage, depth time, last dives information, alarms, time alarms, depth alarms, total amount of dives (and much more) without forgetting one of the most important features: Surface Interval. Some offer USB connectivity for firmware updates along with the ability to download your logs to study your dive profiles. Additionally it can be worn as your regular watch daily (our staff sure does!).
