What is one of the fundamental rules to be followed to ensure safety while diving?

Always dive alone
Know your equipment and plan your dive
Use the same equipment for every dive
Avoid checking your dive computer regularly

The correct answer is: Know your equipment and plan your dive

The principle of knowing your equipment and planning your dive is crucial for ensuring safety while diving. Familiarity with your gear allows you to operate it correctly and effectively, reducing the risk of equipment failure or mishandling underwater. Proper planning encompasses understanding your dive site, establishing your dive profile, and coordinating with your buddies about depth limits, time restrictions, and emergency procedures. By following this rule, divers can enhance their situational awareness and minimize potential hazards, leading to a safer diving experience. In contrast, diving alone increases risks significantly, as it removes the safety net of assistance in case of emergencies. Using the same equipment for every dive does not account for variations in conditions and personal needs, which can lead to suboptimal performance. Finally, avoiding regular checks of your dive computer prevents you from monitoring important information like depth and remaining air supply, which are essential for a safe diving experience.
