you can get an electronic buzzer, for deer. I have mine on a small switch beside dash, when I hit an area that has deer I turn it on or on highway, I try to keep it off in town areas. In the truck I cant hear it but it points forewards. It keeps making a loud pitch beep that I can hear, the thery is that they can hear you comming way before you get there. I installed one and havent seen a deer since driving with it on, and I truck in heavy deer country. I also have a deer bumper but havent had to use it. Keeping the speed down helps alot, gives you more stopping room.
