Solo climbing

• Roped solo climbing is climbing alone with a rope backup in case of fall. Roped soloing is especially useful in rescue situations. There are two ways to rope solo:
• * Lead solo, in which the climber uses a self-locking device which is used to arrest a fall. One end of the rope may be anchored below the climber with the coils of rope in a bag on the climber's back, or for single-pitch climbs the device may be secured at ground level, and the climber tied into the end of the rope.
• * Top rope solo, in which the climber uses a self-locking device and climbs as if top roping. If weight is put on the rope during the climb, it is a form of aided climbing.
• Free solo climbing is perhaps the best-known solo technique. The term describes climbing without the use of any rope or other forms of protection, wherein a fall could result in serious injury or death.
• * Deep-water soloing, or psicobloc, is a subtype of free solo climbing performed on cliffs overhanging water so that in case of a fall, the climber lands safely in the water.
• * Deep net solo is a subtype of free solo climbing in which the climber has a net below them and climbs without a rope. It is a newer version of deep water soloing that can be done indoors.
