Knock only: no cross puff or bell. There is a zipped pocket on the back for tags/cards. I really like the locking mechanism. Very quiet, light. I liked that the kit included a range finder pouch and seat belt. If you don't have a harness, this is a great opportunity to get you involved in the field. At the moment I bought a molle pouch (for tokens, bells, flashlight, extra ammo) which I tie to the opposite side of the range finder. If you are serious about hunting. That's a great start. The only products I recommend over $100 are the standard Vector suspension.
