25' up a tree early in the season when there is still plenty of cover and at close range, where you are out of their peripheral vision, You can pretty much be a rookie, ware hot pink, Knock your arrow off the rest, mumble cuss words, and still manage to get a shot.

Later in the season things change, your cover is on the ground, deer can spot you much farther away because you are closer to their center of vision. Many other things bring you closer to their center of vision, having to place your stand low, in rolling hills (wrong side of a ridge) and skylighting yourself among other things is where open pattern camo come into play.
Deer dont see the same as we do, but they are far from being blind. Evenif one picks your shape out, the way you make eye contactcan make the diference in if you get a shot or not.

Major camoCo's. coming out with open patterns is kind of a bitter sweet deal. Where the custom camo Co. have catered to the bowhunter with the open patterns and great materials for the bowhunter, I am hopeing these major camo manufactures with their noise, fade in one season open patterns sold at wally world dont put the smaller custom bowhunter oriented guys under.
