Night Diving Specialty
The ITDA Night Diving & Limited Visibility Specialty Course prepares divers to safely explore the underwater world after dark and in challenging visibility conditions. Across four modules, you will learn the definitions and environmental factors of limited visibility diving, master buddy contact and tether techniques for poor visibility, understand specialized night diving equipment including primary and backup lights, and experience the unique protocols of planning, executing, and safely completing a night dive. Topics include silt-out management, light communication signals, navigation by compass and natural features, emergency procedures, and marine life behavior at night. This course builds confidence and expands your diving capabilities into one of the most rewarding specialty areas. Certification as an ITDA Specialist Diver Level 1 (Night Diving) is issued upon successful completion of all modules and assessments.
