These dive flags fit onto the NEMO Snorkel Tube and are used to signal that a diver is underwater. Your NEMO comes with your choice of dive flag: Red and White, Alpha, or both.
The Red and White flag is used in the United States, Canada, and some other countries. The Alpha flag is used in most other countries around the world. Always check the dive flag regulations for where you’ll be NEMO Diving and make sure to install the proper flag style so that boating traffic will steer clear while your underwater.
