ISnipe is right.....it depends on the terrain,hunting conditions and what type of Game your Hunting for.
Ground Blinds work great in thick cover,tall grass or on field edges when Turkey Hunting or getting in close to a food plot in a field where there are no tree's nearby to use.Ground Blinds work great in large open food plots when hunting Deer with a Rifle/Gun or even in heavy wooded areas.I like using a ground blind when I take a Youth Hunting,we can get closer to the Game and their movements go more un-detected inside a Blind and You can use comfortable chairs and a heater if it gets too cold or if it rains then your out of the nasty weather.We set up several different types of ladder stands and Blinds when Deer Hunting so we have more options and opportunities depending on the area,the weather and hunting conditions!
