RE: Double Bull for deer
I agree with Kevin1, don't spend your money on Double Bull prices with your first blind. There is a learning curve with these blinds and could prove to be very cost-ineffective while you learn how to hunt from a pop-up blind.
I bought a Double Bull T2 and I have had some good times with it. You can never go wrong with extra camouflage with leaves, branches, sticks, etc.
But you have to be more conscientious with these as opposed to tree stands. Don't make the mistake of leaving it in the woods for long. Bad weather will come and you will leave it out there while it gets pummeled and when you do retrieve it won't be worth squat.
Take it from somebody who has experienced this and have seen others do the same thing. Start off with a "starter", cheap, pop-up blind.
