              Comments about Petzl Shunt Ascender:

              If you're looking for something to use for top rope self-belaying, look at the Petzl Basic. I've tried it with this device and feeding rope through required both hands at some points. Also, be sure not to grab the device if you fall, or device will not lock-up. While weighted, it's a bit difficult to unlock, too. Unless you're doing LOTS of rappelling, I would rather use a prusik for backup because of it's lighter weight.

              The main Pro for this device is that it can be easily slid up or down the rope. Most other ascending devices slide up fine, but need to be undone to slide back down.

              Bottom Line No, I would not recommend this to a friend

                • Self Belay

                Comments about Petzl Shunt Ascender:

                I use it for self belaying but the trick is to add something as a chest harness to mantain the shunt the highest possible, and to add some weight to the end of the rope, that way the rope feeds smoothly trough the shunt, no hands needed. Also is very safe as a backup brake for rappelling.

                  Comments about Petzl Shunt Ascender:

                  This device works great for self belay top-roping and since it uses constriction of the rope as its form of braking, it puts minimal wear on the rope (compared to ascenders with tiny teeth). Just be sure to weight the rope, either by winding the coiled rope up onto itself or tying a sandfilled milk jug to it, this way the device slides easily up the rope with you and locks off solidly. The included instructions diagram well how to use.

                  Bottom Line Yes, I would recommend this to a friend

                    • For me Fixed lines

                    Comments about Petzl Shunt Ascender:

                    Dont be fooled by reviews from those who dont know what they're doing; this is a great device for top rope soloing. I have already completed hundreds of lines on this device (from 5.8 to 5.12c) and find no real issue as long as one knows what theyre doing. In one review someone states that its "feeds rope difficultly", this is only a problem if you dont know how to fix line; after setting up the rope, stuff remainig rope into bag, tie it off (overhand) so that rope bag is hanging about a foot or so off the ground. This provides adequate wieght to insure feeding will never be an issue. I personally (I dont reccomend this)rarely back it up but if i do (generally on easy slabs where i could fall flat on the device) with overhand knotts between me and ground(if situation to do so presents itself) or usually with a prussik loop (note to newbies; a lot of sharma lovers and REI coulpes will tell ya its not safe, i however find it next to bp). NOTE; if you doubt the safety of top rope soloing, its probably not for you. I do not 'reccomend' it to anyone. Dont use the rope shearing devices like the BASIC or MINITRAXION, they are harsh on youre rope and i personally have sheared the sheath of an 'old' rope of mine whilst taking a nasty spill on a traxion while training on my buddys wall.
