I wonder if it works. Doesn't seem like a bad way to find some free bone. Obviously not many people would buy it for $230 but it doesn't seem like like it would be that hard to make. "In the evolution of the Rack Trap Antler Trap,our main concern has always been to promote the casting of antlers without causing harm to the animal. Unlike other shed traps that entangle the deer's antlers causing potential harm,The Rack Trap Antler Trap is designed to simply and effectively apply pressure to the antlers, encouraging the natural shedding process as the deer is feeding." There are videos of it actually working on the home page check it out see what you think. Im not trying to seel the product or anything, just seeing what people think. http://www.racktrap.com/Home_Page.html
I have and would love to try one BUT it is illegal to bait in Illinois. So with that said I will not!
I know a few guys who have tried something similiar to those, they really dont work. They did get a few but not worth the money to buy one. You probably would just as good of luck building something yourself. IMO
Made a couple using bungee cords and a feed pan you can buy at Fleet Farm. 2x4's, bungees, feed pan, made 4 for ~$50. Will send pics when I can with any sheds found.
