I have an Eskimo Quick fish 3 that has about the same hub system as my Double Bull Matrix ground blind. Under 200 bucks for the eskimo. last fall I broke a rod in the double bull and they sent me 4 rods for just shipping costs. last week I broke one in the eskimo and I called them up and they are sending me some also. excellent customer service both companies! I just used one of the extras from double bull to use in the eskimo till those rods get here. I'm learning if you need to force it to pop open,STOP! and adjust a bit. The nice thing about the Eskimo is they have a flap all the way around the bottom that you can bank some snow on and it's fine with a low wind. if it gets really windy I screw down one of the 5 ice screws that come with it about 5 feet from the house and tie it down. works great! you can also use the screws to anchor the corners down also if you want. so if you are gonna use the ground blind just get some ice screws and it should work just fine but you might get a good breeze on your feet if it's windy if you don't bank any snow.
