Solo: Glad you mentioned marketing hype. The same holds for camo, as far as deer are concerned. Turkeys, doves, camo yes. Deer, why bother?
To a deer's eyes, all colors are shades of gray. I've watched does walk up close to guys in blue jeans and Levi jacket, so long as the doe was upwind of the fella.
MattVDW, any noise you make cocking the hammer will cause more problems than smell or "shine". If you walk quietly, non-rhythmically, into the wind, smell won't really matter. If you sit, do your best to imitate a rock. When you move your head, first move your eyes, and then *slowly* turn your head. Position yourself with the wind in your favor, with respect to the probable direction to see deer...
