You couldn&';t possibly justify not bringing the Wild Country Ropeman MK1F Ascender with you on big walls because this tiny device is super versatile in the vertical world. Use it as a prusik or pulley for hauling loads or self-rescue in emergency situations. It&';s simple to place 10-13mm ropes through thanks to the forged sideplates, easy to release thanks to the flat cam profile, and superlight thanks to the forged alloy construction.
