In an effort to insure universal, easily understood signals between divers, [35] the Recreational Scuba Training Council agencies together defined a set of hand signals intended for universal use, which are taught to diving students early in their entry-level diving courses. [34] Hand signals may also have more than one variation that may ...
The diver hand signal for starting the descent. Descents may be made along a shot-line, along the slope of the bottom, or in open water clear of any physical or visual cues to rate of descent other than the depth gauge or dive computer carried by the diver.

DIR divers must be competent at underwater communication by hand signals and light signals, and to use them to ensure that they are always aware of the status of the rest of the team. DIR divers have an extended range of hand signals, some particularly relevant to overhead and decompression diving.
