Diving Related Features

The most basic feature that may be included is a maximum depth indicator. This is useful for logging dives. Some watches have depth sensors that display current depths as well. Both are often linked to alarms that are set off if a preset maximum depth limit is broken. Rapid ascent alarms are another useful feature. While dive times are displayed using the bezel on an analogue watch, digital watches may have a pressure-sensitive dive timer that switches on automatically when you are just below the surface and is logged when the dive ends. Temperature displays, while not so important during a dive, are useful when logging dives. Some divers use the function to note what suit they need at certain temperatures.

There are dive watches that have the capacity to log dives. Some of these models simply log the information as seen on the display. Others record information that can only be accessed when downloaded on to a home computer. Dive profiles and information printouts are useful for making accurate dive logs that can be stored on a home computer.
