Black Diamond Positron Review

Due to the keylock gate design, the Black Diamond Positron is one of the easiest carabiners to unclip from bolt hangers on steep routes. Also, the keylock makes this a great carabiner to rack nuts and gear on (it won't get hung up as easily on a sling). Other than that, this is just a great work horse biner. It's not light but it works in a variety of situations, is easy to clip and handle, and gets the job done.
