I have killed about 20 does with mine and passed up many more does with mine. Have seen one buck mount the decoy and have had several bucks not like the decoy more this year. I have not used it much in the past couple of years, but will use a buck or a buck and doe decoy. I have mostly used just a doe decoy. When a doe gets mad at a decoy she is killable. The last time I used mine, my brother and myself hunted a large field. I told him to hunt beside me and we climb about 30 yards either side of the decoy. He wanted to hunt a different spot. Just before dark 2 different groups of deer came out by me within a few minutes of each other. One doe out of the first group was spooked by the decoy, she stood out in the field for about 20 minutes blowing at the decoy, some of the loudest I have ever heard. My brother was happy he hunted away from me, he thought. A few minutes before she quit blowing, I looked at the decoy, I had been watching her more than the decoy, and a small group of does was right behind the decoy, the biggest one had her nose right up to the tail of the decoy (she dressed 98 lbs) and I almost could not believe it, I shot her she went about 90 yards and piled up. All while the other deer was blowing like a hurricane.
