Briefly describe what you should do if you experience stress, light failure, buddy separation or disorientation while night diving.
a. Stress: Stop, breathe, think and then act; breathe slow, deep and regular.
b. Light failure: Switch to backup light and signal your buddy.
c. Buddy separation: Look for glow of buddy’s light; search for one minute, then surface.
d. Disorientation: Without a reference line, hold on to your buddy, hug yourself, watch your bubbles or look for the bottom if the visibility allows.
