Description
A diver down flag, or scuba flag, is a flag used to indicate that there is a diver below. It is red with a white stripe from the upper left corner to the lower right corner. It can be placed on a boat or on a Surface Marker Buoy.
Purpose
It is used to notify to any boats to steer clear for the safety of the diver.
The use of this flag is required by law or regulation in many US states and Canada, as well in many other countries all over the world. Usually the regulations require divers to display the flag and to stay within a specified distance of it when they are near the surface. As well there is often a larger zone around the flag where no boats are allowed to pass. Some states also prohibit the display of this flag when there is no diver in water.
Other uses
Today the red and white flag is so strictly associated with scuba diving that it is also used to indicate a place where there are services for divers, for example stores selling or renting diving equipment or scuba service stations. You can even see it often on car windows or bumpers of avid divers.
Signal flag ALFA
The international Signal flag A (letter ALFA) is used as well to communicate the presence of a diver in water, but the meaning and the purpose are slightly different: it means that diving operations are restricting the ability of the ship to maneuver. As recent U.S. Coast Guard Notices to Mariners emphasize:
The ALFA flag is a navigational signal intended to protect the vessel from collision.
