I agree with Pat on this. Years of riding in small deer country tell me they don't work. 1.5 million head of whitetails in Alabama. Deer have nearly the same hearing frequency as us humanoids. If you can't hear it, they can't hear it. Save you $10-$80 and buy shims, jets or chrome, maybe some cheap driving lights and turn them out a little to see deer quicker. I ran over a rabbit Friday evening - tasted pretty good with a little rosemary and coriander.
Ride Safe,
