SCUBA DIVERS SIGN LANGUAGE MANUAL
James P. and Lean Smith
The ability to communicate effectively under water is essential to safe diving.
A misunderstanding between divers could mean the difference between life and
death. This book expands standard “emergency signs” through the use of signs
adapted from the hearing impaired. The signs are easy to learn, to use, and to
understand. They will make diving a safer and more enjoyable experience.
