What equipment feature is known for offering an advantage in durability during night dives?

Impact resistance is a crucial feature that significantly enhances the durability of equipment during night dives. This characteristic ensures that the diving gear, particularly lights and other essential tools, can withstand potential bumps, drops, or accidental contact with hard surfaces common in low visibility conditions. Because visibility is limited at night, divers are more prone to colliding with their surroundings, making it essential for their equipment to endure these stresses without malfunctioning.

In contrast, heavy weight construction could add to the overall burden for divers, potentially impacting their buoyancy and comfort in the water. Standard filament bulbs may not provide the best performance or reliability in challenging conditions, such as those found during night diving, where brightness and battery life are critical. Lastly, adjustable brightness settings are beneficial for managing light output but don't necessarily enhance the intrinsic durability of equipment. Thus, impact resistance stands out as the key feature that addresses the unique challenges faced during night dives.
