The NAUI Diving Hand Signals are standard in the United States diving community and are usually recognized in other countries as well (figure 3-57). As a certified diver, you must be able to correctly identify and use each signal. Once you start using them, they are easy to remember. Remember, for a signal to be effective, all concerned must discuss it and agree upon it before you start the dive. Proper use of signals is necessary for every dive. Be sure to discuss the signals you are accustomed to using with any new buddy. Underwater Communication You probably realize by now that communication is not easy under water. When you give a hand signal, you must display it distinctly and you must wait for a response from your buddy. Your buddy acknowledges the signal by either repeating the signal or giving you the okay signal (figure 3-58). Along with the standard hand signals, divers create their own hand signals. Some divers even learn American Sign Language to expand their vocabulary for underwater communication. Always remember to review your hand signals with your buddy before each dive. You can write messages to your buddy on an underwater slate (figure 3-59). This is a handy way to give detailed messages. You can also use the sense of touch to communicate. You can touch your buddy to gain their attention or to let another diver know you are nearby. Try to avoid touching another diver when you are behind them, especially if they are not aware of your presence. It is easy to frighten someone in this situation. You can use and hear audible signals under water although you cannot determine sound sources by direction under water. You or a boat can produce sound signals. Diver-produced audible signals include rapping on your cylinder with a knife or other hard object, or using special full-face masks or devices that allow you to speak to your buddy under the water.
