Review the hand signals below

Underwater communication is important. Hand signals are the primary way you communicate with other divers. Begin by getting your buddy’s(ies’) attention. You can rap on your cylinder with a clip, slate edge, finger ring or other hard object. You can also get simple “cylinder clangers” made especially for making attention-getting sound.
