Scuba Dive Signals

Access a handy list of dive signals to safely communicate underwater while scuba diving. This contains a list of hand signals generally recognized by the Recreational Scuba Training Council and its member agencies (PADI, NAUI, SSI, and more).

Once you've studied up, you can quiz yourself on what you've learned-- the app will show a series of five dive signal descriptions and give you a choice of three different pictures-- only one will match, so choose wisely!
