What is the purpose of a dive flag?

The purpose of a dive flag is to signal to boats that divers are present in the water. This is crucial for ensuring the safety of divers, as the dive flag alerts boaters to be cautious in the area to avoid accidentally hitting divers who may be submerged. The flag typically used is either the Alpha flag or a rectangular dive flag, depending on local regulations, and it serves as a clear indicator of where divers are located. Maintaining safety in the water is paramount, and having a dive flag helps prevent accidents by making divers visible to approaching watercraft.
