Don't know if it would do any good, but the sheep herders around our property in Arizona had some kind of pot rigged up where water dripped into a bucket of some kind of chemical and set off a loud boom about every 15 minutes. Can't think of what they are called, but can be bought at the stores. It kept the coyotes and retirees jumpy and off the sheep. I figure that if it doesn't work for the deer, at least it will make them less jumpy when they are in season and maybe I can get a second shot since I usually miss on the first shot anyway. I'll figure out what they are called and let you know. Sheep folks said they weren't that expensive and well worth the effort.
