We've all seen the ads for uv killer clothing treatment. Looks like it works if your hunting under a black light but does the deer really see in the uv spectrum? Does anyone use this product & have you noticed a difference? I hunt from the ground and am always looking for an edge. I had a gift card for cabelas and while I was there, I picked up a bottle to try. Was wondering if I wasted the credit I coulda used for some more code blue. I cant say my camo is bad because I had 3 doe and one hunter from 13-20 yards of me & they didnt even know I was there. The hunter eventually spotted my orange back tag and apologize as he left. p.s. if it werent for a picker bush I'd have filled a tag.
