I almost got ran over by a doe that busted my buddy set up on a trail about 150 yds away while wearing mt ASAT leafy suit. I bleated at her at 1 1/2 yds and it took her 20 yds to stop... We played peek a boo for over 20 minuutes, but she never spooked...
I made my own ghillie from instruction on the web, but modiifed for bowhunting and have many encounters with deer OTG...
sometimes i can honestly say it helps, but many times I think its overkill.. I think if you stay in the shadows and move slow, it helps a lil bit... but it still helps and I need all te help I can get many times...
