Bone collector range finder - Bushnell 4x20 Bone Collector Edition Laser Range Finder

I used this to survey my land with a -1 yard accuracy. I verified this with a 100ft tape measure. I still had to use the tape measure. Trees and branches can get in the way and give you a different reading. This would be good for wide open spaces. I'll use this for archery hunting. It's small enough to fit in my pocket. FYI it doesn't come with a battery.
