Great article Shawn.
Another trick I found helpful was to use my GPS, rangefinder and compass in concert.
My treestand overlooked several hundred acres of old clear cut and was now so choked up with sapplings, walking on the ground presented a problem. Dropping an animal in the thicket would pose a problem as everything at ground level looked the same. I did some thinking before commiting to hunt this location and this is what worked for me.
I shot my buck at 378 yards from the stand. From my vantage point, I could see where he expired, so I took a compass bearing from tree to deer. I then made sure my treestand was logged into my GPS. I didn't want to drag the deer all the way through the thicket to where I was, so I drove the truck to the closest logging trail to the deer. From there, I simply used my GPS to show me distance and reverse compass heading from where I was to my treestand and started in making corrections to my travel to make the numbers match and viola, there he was. Only a 65 yard drag and by using my GPS to the flagged position where I left the truck, it was pretty much in a straight line.
I don't see why it wouldn't work over a longer distance as long as your GPS gets a good signal.
Just my $.02
