What communication techniques are recommended for night diving?

• A. Using verbal commands
• B. Hand signals remain effective
• C. Written notes underwater
• D. Digital communication devices

Answer: (B)

Hand signals remain effective for communication during night diving due to the limited visibility and challenges posed by darkness. In an environment where verbal communication can be hard to discern, especially with the added sound of equipment and the surrounding water, non-verbal communication becomes crucial. Hand signals are widely recognized in diving and can convey important messages quickly and effectively, helping divers stay connected and informed about each other's status and intentions. While verbal commands may be ineffective in certain situations, written notes are impractical to use underwater, and digital communication devices, although sometimes available, may not always be reliable due to potential issues like water resistance or battery life. Hence, the use of hand signals remains the most reliable and universally accepted method for communication in night diving scenarios.
