If you want to climb faster without wasting all your power immediately, check out Petzls Pantin foot ascender! The Pantin uses the lifting energy of your feet in order to support you while climbing. Therefore, the foot ascender saves you a lot more energy than a regular hand ascender. In order to achieve maximum power efficiency during big wall climbs or cave expeditions, you can combine the Pantin with other ascenders, as well.
The range of the strap is adjustable. Moreover, the ascender is available for either the left or the right foot. The clamping cam features a set of teeth, which is very practical when your rope is frozen or full of mud. As usual, Petzl paid attention to detail: thanks to the side slits, the device practically cleans itself!
Note: The Pantin is not part of the PSA. It merely assists you while moving along the rope!
