ORIGINAL: Rob/PA Bowyer
I prerange many things with my laser rangefinder but I don't mark it out on the ground. I have my range finder on my chest with those bino straps, a quick check and I'm drawing my bow.
I'm with Rob on this one. I usually range things out when I first get in the stand and then periodically throughout the time on stand to make sure I remember everything. This is my first year hunting with a single pin adjustable, so it will come into play a lot more these days.
