How many lights are recommended for two divers to ensure safety?

• A. 1/1
• B. 2/2
• C. 3/2
• D. 4/1

Answer: (C)

For night diving and limited visibility conditions, having adequate lighting is crucial for safety. The recommendation of three lights for one diver and two for another addresses the potential challenges divers may encounter in low-light environments. Each diver carrying their own primary light source is essential for visibility; should one light fail, the diver still has a backup. Additionally, having an extra light with one diver ensures that they can assist the other diver if needed. This setup provides a redundancy that is vital for safety during night dives, allowing divers to effectively communicate and maintain visibility to avoid potential hazards. Thus, the choice of three lights for one diver and two for the other emphasizes preparedness and safety, given the unpredictable nature of underwater environments at night.
