The double bull blinds are awesome work on almost everything. Set them up in the open where deer can see them from a ways off. If you surprise a deer with them its like some one putting a different woman in your kitchen it just jumps out at you. make sure you have mesh screens in place and arrows w/ broadheads taht will fly out the screen. If you feel a breeze the deer can wind you, but bout 80% of your sent will be left in the blind. The double bull blinds are expensive around $400. but the fabric, fabric stretch, set up and take down, plus the mechinisms in them make them supperior to any other blind on the market. I sell archery gear for a living. I feel sorry for anyone who tries to go the cheap way and doesnt buy a double bull. The guys from double bull are also putting together a situational video to help show when and how to use the blinds. With this added knowledge anyone can be deadly with one of these.
