  • Pirana offers 3 different braking positions, according to the weight of the user, the rope diameter and the terrain
  • It also offers 2 points where the rope can be angled to adjust the descent speed
  • A plastic attachment ensures perfect support for many types of HMS locking carabiners
  • Carabiners with cross sections of 12mm (e.g. Petzl Attache) will provide a very tight fit in the small hole, so tight that it takes a bit of pressure to get the carabiner in
  • Snug fit creates a rigid carabiner/descender unit that helps to reduce risk of loading carabiner across the gate; also stays securely attached to harness to help prevent loss
  • Designed for use with the ''Rapid'' technique, which foils formation of a lark's head hitch around Pirana body and reduces kinks without curbing friction
  • May be used with double ropes, but not all braking positions may be usable depending on the ropes' diameter
  • The Pirana can also be used to belay the leader

Rated 5 out of 5 by from Great For Canyoneering This product is fantastic at what it's designed for, canyoneering. It's relatively easy to use and the way you can take your rope off without taking it off your carabiner makes it great for exiting in pools. By wrapping the rope around different ways you can vary the friction greatly depending on your preference. That said, this product can cause some rope twist (less than other figure-eights), it can leave some residue on your rope, and it's probably not the best for belaying. However, this thing is awesome for general descending and 100 ft rappels or less while canyoneering, especially in wet canyons.

Rated 5 out of 5 by from Best Descender Available I have been using this descender for years now. It is AMAZING! Very easy to use and very predictable. Whenever we are teaching someone that is new to repelling/caving we set them up with this descender. I love that it is super easy to adjust your speed and you can also tie yourself off so you can hang freely from your rope without using your hands. If you will be doing any sort of descending you NEED to buy the Pirana!

Rated 5 out of 5 by from Versatile descender This is an extremely versatile descender. My daughter (110 lbs) and I (170 lbs) both use it, just with different wraps to adjust the friction. Works well on a wide variety of rope materials and diameters, wet and dry. Works perfectly with the Petzl William 'biner.

Rated 5 out of 5 by from The best rappelling device in the market This product is the best rappelling device ever made. Easy for beginners to use. Awesome friction points for single rope rappels. Definitely made for canyoneering though. Sweet for rappels when you need to pass a knot. You can lock yourself off to the rope so that you can release your brake hand. Nice tight fit to a carabiner insures not to lose your gear in a water hole. LOVE IT!!!!

Rated 5 out of 5 by from great decender I bought the device for caving, but once i used it the first time, i hung up my atc and figure 8 and only carry this. it's easy to use and with the braking, i can use a smaller rope and still go down slow if i would like. my girlfriend even has one and she is an absolute beginer and has not trouble with it.

Rated 5 out of 5 by from Easiest Descender ever!! This is by far the easiest rappel device. There are several ways to increase friction for a more controlled descent. What I like best is how easy this device will lock off. Easy to use & well built.
