These ascenders are where the term ‘jumaring’ comes from. The integral handles are great for longer ascents. The trigger, which keeps the cam in open position, also acts as a safety block to the cam so that it can’t completely be opened when it’s in clamp position. This is a great safety feature, particularly when down jugging. This does however, require two handed manipulation, or a lot of trained dexterity to completely unhitch the ascender, so it is not as easy to clear pro, knots, ledges, etc...
