• Great versatility, ideal for technical rescue:
  - locking system with integrated progress-capture pulley allows the same device to be used for descent and hauling
  - can be used in both a single or twin primary system and in a back-up belay (more information on this technique in the product’s instructions for use and in technical tips at www.petzl.com)
  - lower connection point can be used to create different types of hauling systems
  - hole in the handle for installation of a distance control cord
• Easy to use:
  - easy rope installation, thanks to the markings on the device
  - ergonomic handle allows the rope to be released progressively and enables comfortable control of the descent
  - immediate shift from lowering position to hauling position without having to transfer the load
  - AUTO-LOCK system allows the rope to be blocked automatically when the handle is not in use. Once locked, the rope can be taken up without having to manipulate the handle.
• Efficient for handling heavy loads:
  - integrated progress-capture pulley with very large diameter sheave mounted on sealed ball bearings; rotates in only one direction for excellent hauling efficiency
  - sheave is faceted, creating additional friction zones for the rope and thus additional braking on descents
  - integrated brake on the device to adjust the friction based on the load and the rope diameter
  - handling of loads up to 250 kg
