I use the roundhouse 360 by ameristep. The deer dont seem to mind after its been set up for awhile. Now when Im out turkey hunting and set it up in the middle of a field the deer act like its the plague. the shoot through mesh does the trick for me. I also use a bow and not a firearm with it. If you use a firearm:
1. make sure the muzzle is OUTSIDE THE BLIND
2. wear ear protection of any kind, even rolled up TP or paper towels.
I about blew my ears out shooting a turkey out of my blind when I didnt stick the barrel out the window.... Stupid.
