I just got through reserching and buying a ground blind. I chose a Double Bull BS5. For me and my 5 year old son its got the features and room we need. They make great single person blinds also. I went to the factory in Minnesota and had them give me insight to ground blind hunting. I was there for 2 hours. These guys are hardcore bowhunters. I learned alot! Each year they put out a new video(all bowhunting). You can call them and order a video for $5, most of the video have 20-25 turkeys and 8 to 10 deer hunts, and a few misc hunts like bear or bobcat......
At any rate Double Bulls are more money but are extremely durable , set-up in seconds, quiet and no wind flap noise.
