I bought this for shooting and this is the first rangefinder I have ever had any experience with and I have been very happy.  It is a very simple setup.  The button turns on the reticle and you just point it and push the button again and it displays the yards.  After a short time it shuts back off.  Doesn't get much simpler than that.  I have read reviews where some people are unhappy because thiers only reads in meter instead of yards.  There is a micro switch under the cover (kinda hidden) that switches between yards and meters.  Overall, a great purchase.
