ABSTRACT:
A generally J-shaped snorkel tube with a mouthpiece at its lower end carries an attached whistle on one side near its upper end. The whistle is in a hollow projection on one side of a sleeve that is slidably inserted over the upper end of the snorkel tube. The whistle and sleeve are a separately formed attachment for a conventional snorkel. The whistle does not obstruct the top opening in the snorkel tube through which the use can expel water from the snorkel by blowing into the mouthpiece. The user covers this top opening with one hand when blowing the whistle.
