Dave,
I use double bull blinds, I have the T 5 and T 2 I just recently purchased the T 2 and I enjoy it a lot more since I hunt by myself.
I purchased the Montana decoys, the first caution you want to have is they looks so real you Do Not, Do Not want to use them during gun season. Rather it's on private land or public land. I have heard a couple of stories of guys having them shot at.
But the way you want to use your decoys, is placed them about 25 yd. away from your blind set up. And you want them facing you, the reason for that is, the deer will come in and more times than not, they will want to make eye contact with the decoy, set them 25 or 30 yd. out, the deer will come in between you and your decoy to make eye contact, if it is during the rut, sometimes you'll see an aggressive buck rip your decoy out of the ground, best be taking your shot long before that. The main reason for the decoy when you have a blind set up, is to take the attention off of your blind. Another thing is do not spray scent directly on the decoy, I have taken fishing line and attached it to a small piece of lambs wool, my lambs wool is to different colors white on the bottom, and brown on the top. I cut it just like the size of the deer tail, I attached to the decoy, and I will pull it to make it look like that deer decoy is waging its tail.
It's best to use a buck and a doe or if you only have one, a buck, a single doe will not bring in bucks. The doe's will stand off at a distance if you just have a doe decoy, now there are the exceptions. But most of time they'll stand off at a distance, stomping their foot, trying to get its attention, they will do that for as long as 45 minutes, and then they will bolt off. The reason for that, they get awful suspicious when it doesn't move. So the tail thing with the fishing line will give them some movement to look at. If you have two your chances are better that you will attract both buck and doe.
I have talk to someone that uses decoys more than I do, she has been doing it for over 30 years, she now uses real-life size lightweight decoys. And her system is, to hide the decoys head in the bushes like it is eating, she says if they can not see the eyes there are more apt to come in. I don't have the experience it's just her information. It's a lady that owns a professional bow shop, her husband and her son have had archery business for 30 years, she us to shot with a 40 recurve, and now she hunts with wheels but they are 45 lbs. that is all she's ever hunted with. And she says she has the best of luck with buck decoys. She averages three deer a year
Make notes about everything that happens with your decoys, and you'll learn from experience. The decoy is also qualify for the 50/100 rule. You don't want to have your decoys in a secluded area where they surprise the deer when they come into that area, you want them to be able to be seen from a good distance.
Good luck with your decoys they are definitely a lot of fun and you have started with the best ones there are. I do hunt public land, still be cautious. There are certain public lands in my area I wouldn't use the decoy ever. Even if it's only bow season, we have some people here that have no conscience, and no respect. Poachers.
Good luck to you
Carl
