Belaying is a climbing technique used to manage the rope for a climber. It involves one person, the belayer, who holds the rope securely while the other person, the climber, ascends or descends. The belayer ensures that if the climber falls, the rope will catch them, preventing a dangerous drop. To belay effectively, the belayer uses a device, often called a belay device, which helps control the rope's movement. Proper belaying requires attention and communication between the climber and belayer to ensure safety. This technique is essential in various climbing activities, including rock climbing and ice climbing.
