Hey I'm just trying to rationalize this. Maybe I'll learn something.
In my experiences......"catch my scent"? RARELY does this end well. "Catch sight of something"? I've killed a few that saw me. Could've killed a lot that saw me (one was just last night).
VERY similar occurrence, last night. Lone doe.....enters from the S. Wind is W and in my face (how I was facing). She enters from my left.....and gets to 15 yds and gets antsy. I thought I was still (I watched her enter), but she "seemingly" caught my outline in the tree I was in (who knows?). I was on the back side of the tree from where I thought they'd be coming in. She was also below me a little in elevation (8'?). I had doe urine out....but she didn't get downwind of my scent rag .......I don't think

.
Even after spotting me.....I still could've shot(at) her (after she settled down).
Did the wind swirl.....even a "little"? Don't know. Did she see me? Don't know. She never got to my entrance trail. I do know that.
All I'm saying is.....too many times I'm seemingly spotted in a tree.....and still have opportunities to take the deer....for me to think a half-hidden flashlight would cause a deer to bolt at it's UNMOVING sight....is a stretch. Would they bolt at a "new" stick or limb that's fallen the night before? Do you think they know the difference from 45' if they can't smell it?
