ORIGINAL: bowtech die hard
I've used them in the past but don't have one of my own. I got lucky and got to sit in a double bull matrix 360...that is the next blind that I will own period. Yeah, they work though!
I have a double bull and they are GREAT... If you brush it in a little bit the deer have no clue what it is. I actually had them eating some of the brush off of it the very first day i put it up. I wasn't hunting in it that night but i could see it from my treestand. since then i have hunted it 2 times and the deer get really close.
