What does a dive flag also help prevent?

A dive flag serves multiple important functions when divers are in the water, one of which is to alert nearby boaters to the presence of divers below. This visibility helps prevent accidental collisions with boats, as it signals to boat operators to steer clear of the flagged area. Boaters are trained to recognize dive flags and understand that they indicate divers are in the vicinity, prompting them to exercise caution.

In contrast, while other aspects may be related to diving safety, such as shallow dives, swimming in currents, and underwater navigation, they do not directly pertain to the primary purpose of a dive flag. Shallow dives refer to the depth of the dive and are managed through proper dive planning, while swimming in currents and navigating underwater involve skills and awareness but are not addressed by the use of a dive flag. The primary importance of the dive flag lies in enhancing safety by preventing potential dangers from boat traffic in the area where divers are active.
