If you are just starting to learn top rope or are into multi-pitich glacier climbing this ATC has something to offer. No matter where you are in your climbing carrer the black diamond ATC guide has what your looking for. Allowing for up to 11mm rope, this ATC is compatible with just about any rope you may encounter. For beginners this is the one for you because it gives you the capability to grow without having to run out and buy another ATC down the road. For veterans this ATC's guide function is a dream come true. Overall I highly recommend these piece of equipment.
