Most ground blinds I've tried are not designed for a bow hunter. They just don't give you the room to manuver and go to full draw without your broadhead ripping fabric or your arm pushing the back of the blind. Even still, they do work very very well. Even your most basic model will allow you the opportunity to strech your legs and move around a bit without spooking the deer you didn't see. They also contain your scent exceptionaly well. I've had deer walk downwind within mere feet of the blind and act as if I wasn't there.
By all means use one if you can find a nice big blind at a good price and know a spot that the deer get close. You will be suprised at how well the blinds work.
