Opinions vary widely on the topic of cover. Many never seem to have enough, while hunters like myself prefer to use the least amount possible.
Hunting revolves around your ability to elude perception. I have spoken quite a few times on the topic of scent prevention. Covering your scent and making sure deer don’t catch wind of you is first on the list. Next in line is your ability to stay hidden. There has been plenty of debate as to how deer see. But more important than how they see is what they see. Over time, hunters can make their own interpretation as to what and how well deer see. Using your experiences afield rather than an electron microscope will give you more information. We may never know exactly what deer see, but can be sure of what they don’t.
