The rappel kit consists of a 50-meter length of cable capable of supporting up to 200kg wound on a spool attached to a light-weigh harness. The cord is attached to a solid point with a piton or hook. The user can then descend the line at any speed desired.
As an option a motor and battery can be attached to the spool allowing a powered descent or ascent at up to 40 meters per minute. The battery lasts for two full ascents before requiring a recharge.
