The Petzl Pirana Descender provides excellent rope control and a smooth lower when you're rapping long lines with heavy loads. Rappelling a 150ft single line with a heavy pack is no longer a guaranteed white-knuckle horror show; you won't even notice the weight when you use the Petzl Pirana Descender. Its two breaking spurs allow you to increase or decrease friction on the go and are used to secure the device, so you have both hands free to build the next anchor.
Bottom Line: Big haul bags and long rappels are no longer a dreaded combination thanks to the Petzl Pirana Descender.
