Whether you need to show your buddy something fun, or to let your buddy know about a possible or actual problem, Sea Signs has a vocabulary chosen especially for divers. As a recreational diver, or a professional, it’s a quick, effective and inexpensive tool for communicating underwater that is easy and fun to learn, teach, and use.
