Query: Must have a steady hand!

I have found results up to 150 yards to be ok for hand holding. Past 150 you need to rest the Rangefinder on either a cart, Push cart, or even a tree. A monopod would also solve this problem. It does as advertised and has made a huge difference in my approach shots. You will quickly find some markers at your local course could be off as much as 20 yards. Pine trees work out to be the easiest to get a reading from though still difficult past 300 yards. After much research this is the best for the buck. Would highly recommend.
