I use a rangefinder to check distance initially.....to that big oak, to the blow down , to the trail. All reference points around me.I do this when it gets light enough the first couple times in a given stand.
I do that as well. I also carry it with me on my belt for whitetails and arround my neck for game out west or for caribou for quicker access. I just leave it on my belt in case I forget how far that marker tree was, or how far that marker bush was or whatever. That way, when a buck is on his way in I do not have to do any ranging. I memorize markers every five yards from 30 yards out to 45 yards in all of my shooting lanes (if they go that far).
