Diving knots are specialized knots used in underwater activities, particularly in scuba diving and free diving. These knots are essential for securing equipment, such as buoys, lines, and dive gear, ensuring safety and efficiency during dives. Common types of diving knots include the bowline knot, which creates a fixed loop, and the double fisherman's knot, used for joining two lines. Proper knot tying is crucial, as it prevents equipment loss and enhances overall diving experience. Learning these knots can significantly improve a diver's skills and confidence underwater.
