I started using my decoy about 5-6 years ago and have had quite a bit off luck with it. I will have to say that old wise does are very nervous about them, from my experiences. I have found that they are magnets for smaller bucks, but I have never had the chance to see how they work on a big buck. I like to set it up where deer can see it from a long ways out, as much as possible. Make sure you spray it down with scent killer completely after you set it up. I like to hang a scent bomb right behind the decoy. One thing to remember is that most deer will come in from behind or down wind to scent check it, so you should angle your decoy accordingly. Like I said I have had quite a bit of luck with them but I agree it's not a for sure deal sealer. Wouldn't try to use if your hunting does. Good luck and let us know how it works out for you.
