Grew playing spot and stalk for Whitetails with a bow. Success odds are not in your favor but that type of hunt is a lot of fun.
Basics. Play the wind first. You are not going to beat their sense of smell unless you are always downwind from them.
As ezmorningrebel mentioned above, move at a snails pace. I carry 10x42 binoculars and optically pick the forest scene apart ahead of me.
Pick your stalking path at the beginning of your hunt and scan it first.
I then visually inspect the surrounding areas as I move down my path.
Look for pieces,horizontal lines of a back or belly, any different color,movement like an ear flick.
Sounds are important too, a deer walking can break a stick. A deer chewing on acorns is fairly noisy too.
Leafy suits have become a staple for me. I wear one all the time, facemask included,and have several to match the leaf color and the amount of sunlight that is shinning on undergrowth. Some have optical brighteners in the colors and are easy to stay away from. Dull colors work best.
I have found I can get away with much more movement wearing one, even drawing a bow with eyes on me.They have issues with 3 dimension.
I wear them in stands as well as usually I have to pass the doe test(letting the does go by before the bucks come out)Most of my stands are not high up.
I also trim the leaves of the suit so I can draw from angles without getting caught up in a string.I wear skin tight camo gloves for moving the binos and triggering the release.For this type of hunt I wear rubber boots for a softer sound.
Another tip, at least for me, is do not make eye contact with an animal even disguised as a bush. I keep my eyes averted and mentally prepare for the draw and shot while watching with peripheral only.
Moving like this has given me opportunities at Turkeys and Coyotes with a silent shot.Our fall Turkey archery season coincides with deer season so I always have a diaphragm call with me. Turkeys, in their unmolested state are noisy and a few yelps once in a while not only has a chance for an answer back but might naturally cover some of my noise.
I have my bow set up with an arrow nocked so I am always ready to draw.My rest is full capture but I have used a rubber arrow holder glued to the riser when I ran a Limbdriver rest.
I still use a scent cover spray. Scent Away fresh earth, the other brands smell like lysol to me.
It has kept me from a total bust several times in shifting breezes.Just works in my favorite area.
This turned into a novel. Good Luck.
