These devices had tended to harshly jolt the climber, especially in a short fall, the impact occurring due to the device locking so quickly creating almost a ‘static’ loading which gives a high impact force – less bounce more bang…So with the SRC we took our knowledge of ‘trad’ belaying, which is more dynamic (meaning a softer impact) and developed a shape to keep more dynamism in the system whilst simultaneously helping to lock the rope with low belayer input. So although the SRC is not a true ‘auto-lock’ and certainly not sold as a ‘hands-free’ device it lessens the input from the climber to hold a fall, as well as holding any fall more dynamically lessening the impact force. This means that the climber is less bruised, there is less stress on bolts, biners and harness and less danger of failures in the system.
The SRC was also designed to feed incredibly quickly in a sports situation and so for those ‘quick-clips’ that can mean the difference between success and failure, the SRC is definitely on your side. The SRC is supplied with the ultra-secure 'Belaymaster' karabiner as its perfect partner.
NOTE - The SRC is only meant for use with single ropes of diameters of between 10 and 11mm only.
