Adapting signs from American Sign Language for scuba diving, the author, a NAUI certified diver with 25 years experience, has prepared this book for other divers' instruction and reference. Designed for simplicity in mind, this is perfect for amateur and professional divers alike to expand your communication base beyond the standard signs you use now.
