you can rappel with this, sorta like belaying someone down i guess. Its a bit sketchy but itll do the job

Rappel is a pain with this device. Go old school or get an ATC. It can be very jerky...sp? and I found it to be sketchville.

Unless your experienced in setting up fixed lines for canyoning or caving I would HIGHLY recommend against using this for rappel. There are too many products that cost less than $30 that will be better for rappelling.Only on a single rope or a fixed line. Some people set it up for long rappels on the side of the rope that pulls against the knot, but that's not very safe. Petzl doesn't recommend rappelling with it, and it's just a lot easier to get an ATC and use that.To add to that, I love using this as a rappel device on fixed lines, it is a great and safe option for that.
