Night Diving:Hand signals are possible while diving at night with a change in procedure. To attract attention to yourself, move the light beam from side to side. To signal an emergency, cover and uncover your dive light with your hand repeatedly so as to create a flashing effect with the beam. Remember never to shine your light in other divers’ eyes as you will greatly reduce their night vision for a considerable time. Shine your dive light on your hands to give signals.
