While that is true, a big buck does certainly use all his senses...and in order to take one, you need to over come all....out of all his senses, his since of smell is the greatest...just like a turkey's sight is a much greater advantage to itself than its Ol sensory factor...a big buck uses it sense of smell more than any...Like I've brought out...Chuck use to wear check-ed shirts, and deer are color blind...now, I'm not saying they don't use their sight, what I am saying is that they rely on smelling things at a much greater rate....if this wasn't the case, we wouldn't have to store our clothes in air tight containers, watch what we eat before we go out, make sure nothingsmelly is on our hands when we go into the field, wear rubber boots, possibly scent-lok clothes, make sure our clothes is sprayed down, and/or washed in scent reducing agents, watch the wind, use scents as cover, and not to mention, theirs a muti-billion dollar industry involving the reduction of scent, etc..then and maybe then, if your scent program is flawless, they won't smell you. Bucks also use their sense of smell to communticate through licking branches, rubs and scrapes, all involving their sense of smell, as far as their eyes go, all you have to do is get 16 ft. or above, and don't move...which is harder to do? It is much much much easier to overcome their sight than their sense of smell...So you asked, Why does one have to be more important than the other? Once you can get your scent program that's flawless, you'll be sure to start seeing many more mature bucks....
