Many divers find that night diving is their favorite type of diving. As with all specialty diving applications, procedures are different than those associated with open water diving. The purpose of this course is to acquaint the open water diver with the procedures, techniques, and potential hazards associated with diving at night, or in limited visibility. Becoming familiar with the use of dive lights, and night diving techniques such as navigation, buddy system procedures, communications, buoyancy control, and interacting with nocturnal aquatic life, the diver can safely enjoy night diving.
Night diving requires different skills from diving during the day. The Night Diving and Limited Visibility specialty is the best way to learn about night diving and practice the techniques you will need to become a safe and confident night diver. In this program, you will be provided with all the knowledge and skills you need to safely and comfortably dive at night or in limited visibility conditions. With a combination of online learning and open water training dives, you will learn how to enter and exit the water, use specialized equipment, and how to communicate with your buddy easily at night or in limited visibility. Upon completion, you will earn the Night Diving and Limited Visibility specialty certification and be ready to go night diving with confidence.
One of the most mesmerizing elements of night diving is bioluminescence, so do not forget to look for this natural phenomenon by holding your dive torch beam close to your body or by covering it with your hand to prevent all light from escaping, and then by just waving your hand through the water you should see streams of tiny, marine fireflies dancing off your fingers.
