What is an important practice before beginning a dive?

Checking equipment functionality is crucial before beginning a dive because it ensures that all gear is operating correctly and safely. This includes verifying that the buoyancy control device, regulators, tank pressure, gauges, and dive computer are all in working order. Any malfunctioning equipment poses a risk to diver safety underwater where quick fixes are not possible. By systematically checking all gear, divers can identify potential issues and address them before entering the water, significantly enhancing their safety during the dive. Proper equipment checks contribute to a confident and enjoyable diving experience, minimizing risks related to equipment failure while underwater.
