What is crucial for a diver to remember regarding their dive gear during a night dive?

During a night dive, it is essential for divers to check the functionality of their gear beforehand. This ensures that all equipment, particularly light sources, buoyancy control devices, and any other critical tools, are in optimal working condition prior to entering the water. Poor visibility during a night dive can lead to increased risks, making equipment reliability even more vital. By verifying that everything is functioning correctly, divers can focus on their environment and safety without the distraction or danger posed by malfunctioning gear.

Maintaining equipment or keeping it light, while good practices for diving in general, do not specifically address the unique challenges and safety concerns posed by night diving. Wearing a helmet is usually irrelevant in recreational scuba diving contexts, as divers typically don’t use helmets. Minimizing equipment can hinder a diver's capabilities and effectiveness, especially in low visibility situations where having the right tools is crucial.
