Yeah I've got one, they are brilliant. I have the 3 mode big one, and a mate has the smaller 2 mode one. The chisel function isn't that useful to climbers (although you can solve free climbing problems Jardine style with it!). The main difference is the 2 mode is waaay smaller and lighter, and so If I was buying again I would buy that one. It also seems more efficient with batteries, but not as quick to drill in hard rock |
