Sat in my treestand today on a piece of private property I have hunted on several years. I have never had a problem with deer spotting me, but every deer that came by within 30yds would stop and look up right at me. I checked the wind several times and did not make a single motion, but they somehow still knew I was there. Luckily they never did spook, but I doupt I would have ever gotten a shot if it was a buck. I believe not moving and having the wind in my favor are the only two reasons the deer did not spook. At the end of the day I remembered about people talking about how deer along with several other animals have see in the UV spectrum. When I got home tonight I got out a black light blue (blb) bulb and turned it on. Well my new Bass Pro coverall suit reflects UV light. It had a purple glow to it under the light. I put the light on some of my older camo and nothing happened. I guess I bought myself a new ground blind suit, since I will never wear it again hunting in the open. Has anyone else found this connection with their camo? I know that not all camo has UV reflecting dye added to them, but my new suit sure did.
