No doubt, if you are going to be guided, leave the bugle at home. A cow call should always be handy though to stop an animal, or put the finishing touches on getting him to commit. The Primos hyper lip is a good call and easy to use. I really like the "cow talk" call with the small rubber band set up. I can get alot of different sounds out of this call, from a great calf sound up to various cow calls. I think their web site is www.elkinc.com. They are based in Montanta.
