My attempts to rattle mule deer appeared to be fruitless. There are four antlers attached to a leather shoe lace so they hang.
Whether they produce a different sound or create greater volume I don't know.
While trying to get two bucks to show themselves better while they were sparring did get a view to show they were not legal.
Picked up my gear and slung the lace over my shoulder so the antlers produced a tinkling sound.
Walked within 25 yards of the two bucks and they continued to spar and produced a similar sound as my antlers.
Looked back from 100 yards and they continued to test each other.
Having shot only one white tail, I don't know if mule deer antlers would attract whitetails.
