Descender with three braking positions, designed for use with canyoning descent techniques.

The Petzl® Pirana Descender has three braking positions designed for use with canyoneering descent techniques.

The PIRANA descender offers multiple braking options and can be installed on the rope without removing it from the harness. Designed for use with canyoning descent techniques.
The Pirana Descender by Petzl is a canyoneering descender for single or double rope. The Pirana offers three different braking positions to choose from, according to the weight of the user, the rope diameter in use, 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 any type of HMS locking carabiner. The Pirana Descender can also be used to belay the leader.
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.
Three breaking positions, two friction horns and a plastic guide for good positioning of a carabiner all make the Pirana Descender from Petzl an ideal Canyoneering descender.

The Pirana is a versatile descender designed for canyoneering descent techniques. Multiple braking points give flexibility for different weights and situations, and tight compatibility with 12 mm carabiners creates a simple, secure system.

I love this thing. Its a fairly crazy looking device so it gets some stares from folks who don't know about it. The multiple friction points are a great feature though they don't really matter much for a normal rap. If your canyoneering you'll need them to help slow you and a pack down though. It's a bit more difficult to do the cross over to lock it in than on my Super 8 but not noticeably. It's easy to set up wrong sometimes though. What I mean is that if you use the friction points, you use the lower point first and it's easy to use the top first which gives you less friction. The if you get the William biner with it, know that the fit is very tight. It's hard to get he device on and off the biner so I recommend an 11mm biner or a round biner instead. The William, while an excellent keyed screw gate (also very huge), has an oval cross section. I would just take the device to your local shop to find one that fits best. I say that, because you want to be able to flip the device to the side and down to get it out of your way if your canyoneering. An oval shape just doesn't let you do this. I use a steel biner that's round and it works like a charm. As a belay device it's fairly straight forward. Set it up just like you would to rap and pull down to lock it off. You can use the bottom friction points to add friction to the belay which is nice. I like it a bit more frictiony when I lead belay. The friction is nice for when you are lowering someone after they finish a sport climb too. A bit safer feeling than lowering on an tube style device. It will freak out your friends though. Getting belayed on such a funny looking device is weird. Setting up a releasable or contingency anchor to rap off of will require some thought before you head out to the canyons though. It will be better for your ropes to use a Piranha for a contingency anchor than a munter while giving great fiction in case you need to lower someone. As with all new gear practice practice practice. All that being said. I love this thing. I had seen this in the Petzl catalog and wondered about it and finally got to play with a friend's. I was hooked. I had one a week later. Its the best thing thats happened to the 8 since rescue ears. The set up doesn't allow for a larks head to form, gives lots of options for extra friction and can be used to belay as a great bonus. | |

| I bought it because it looked cool, and I didn't want just a regular old figure 8. I love its versatility, with its variety of set ups and what not. It offers you much more than a regular old figure 8. You can descend, or even belay, so it is a great addition to your climbing gear. I read reviews of it beforehand, and people said the hole was small. They were right. I tried a variety of biners, before breaking down and buying a Petzl Attache. It was a tight fit, but it fit. Petzl says they desire a tight fit, and they certainly accomplish that. So if you don't make the same mistake I did, and pair it with a Petzl biner in the beginning, you will have no complaints. | |

| Product is quickly set up and highly useful in canyoneering situations which require a variety of friction settings. There are times when I need a quick change to more friction when getting pounded by a waterfall. High friction is great if you have to rap with a lot of extra weight (e.g. another person you had to cut loose). Make sure you use something like a "attache" binner. Few others are right for the tight mounting hole. I was trained with a "chain reactor" to extend the device away from the climbing harness for greater control. It took some convincing to get me off the conventional ATC. But once I got used to it I hademore technique, speed, safety and versatility available to me. | |

I'm a climber and I live by the tube-style belay device. A friend introduced me to the Pirana for Canyoneering and there is absolutely no way I would ever go back to a tube for canyons. No matter what rope we're using, from super stiff, static 8mm to totally dynamic 11mm, single or double strand, I have tons of options for friction - low friction for dry descents, add a little when things are wet, lock off during the descent with a quick flick of the wrist (quick mule-knot if I'm going to sit / do something for a while), etc. So many options, so easy to use... | |

| I started using the Pirana recently and love it. They say it's a Canyoneering descender but I would use it any where. I never have to worry about losing it when trying to hook in to a rope in freezing weather like I lost my last figure 8. For repelling it is a lot easier to hook in thanks to never having to remove it from your carbineer. For belaying its different then an ATC but it's almost as easy. Hooking onto the rope is way easier then an ATC. In short it's the best I've used and would say that an extra $20 is really worth it. | |

| Not your typical 8. I love it because it's much lighter then a rescue 8 but still locks off. i wouldn't want to fall on it though as those horny things might poke you but all in all i love this and you can use it to balay if you like just like a regular 8. And who can't beat the name Pirana?? i mean how many people get to ask while climbing can you hand me the Pirana? Seriously! Love it and well I love petzl in generl this one it just an extra bonus. | |

| I am not a big fan of figure eights, for that they twist the rope and leave aluminum residue. But out of all the figure eights I have used this is to me one of the best. You do not have to worry about the rope sliding up and lock off and the added friction makes it great when transitioning from different angle slopes to free descents. It is small and easy to pack. Works great on dynamic rope, but is tight on static rope, more for the rock climber then the caver or rescuer. | |

| Great device, smooth repels and love the variety of speeds you can obtain through the many different friction settings you can set with the descender. My only concern was I did not realize how small the hole was, I had a williams and struggled to get it in. Once its on you won't want to take it off, just plan on leaving the biner attached to it. I ended up buying a new attache so I could have my williams back :) | |

| Fantastic descender! Strong, reliable and capable of being very FAST. The break hooks do a good job of holding you in place when you need it. If you plan on buying a D ring for this descender make sure it fits. Only certain D rings are made to go with it. I called and they recommended item number 262747 Petzl Attache Screw-lock carabiner | |

This is an awesome rappel device. It works great when you are rapping a 150ft caring a pack. It find that a normal ATC can be a little scary while caring a load. I always keep one with me on long technical climbs. You can also use it to belay someone if you choose. This is a must have for every climber. | |
