Is there some where here that has pictures of the hand signals which divers use? I think I already know the signal for Shark but what are the others? Is there a scuba book you guys recommend? like is there a Scuba for dummies?
There is one more site you should check out. www.wrstc.com
World Recreational Scuba Training Council they have established hand signs with pictures its a good guide.
I would check out www.seasigns.com - it is a communications course for divers based on the American Sign Language. We teach the class by internet video or person to person. Becareful of the shark sign. If you do it to a person who is either deaf or know ALS you are really insulting them.
