The R20 utilises innovative design technology using a lightweight, unobtrusive rescue device contained in a small 'back pack' which is attached to a standard harness. In the event of a fall the device lowers the faller gently to the ground in a controlled descent.
The whole rescue process has been revolutionised to contain everything in you need for self rescue in a small back pack which contains:
a parachute type 'rip cord that releases the descending system
a brake mechanism and spool with a 20m cord
a quick release harness for rapid evacuation of a dangerous area
After a fall the devise can be sent a way , tested and re-set for further use.
