RE: Rattle bags.....
I can' t claim to be an expert on rattling, but I did witness my first buck fight last weekend and then last night had the ' pleasure' of hearing a hunter use sheds to rattle with.
The difference in tonal quality was amazing. He was about the same distance away from me as the bucks were that I saw. The bucks were a definite higher pitched Click-clack, while his was a very dull sounding cluck-clunk. The Knight and Hale mess bag with the plastic ' tines' in it sounds much more like the deer than the sheds did, by far!!!
Another mistake I think he made was that he clashed them together very hard continuously, as if they were coming together over and over in the space of a couple of seconds. What I witnessed was completely different. There was a loud clash as they initially came together, but then jush a series of lesser clicks and clacks after they locked up and got into a pushing match, with the occassional louder clicking and clacking as one would try twisting his head, but that was only occasionally. His sounded like they got locked together and then starting doing back flips together.
In fact, I was so frustrated listening to his attempts that I almost yelled through the woods, " Give it up guy! You ain' t fooling anything!"
That' s my two cents. I' m a firm believer in bags now. I have read that soaking sheds in water bring back that ' live' bone or antler sound. Maybe it works, I don' t know.
