I got one a couple weeks ago. I have only been out using it a couple time with my .22 Maverick sniper and a friends .22 ghost. So far I really like it. The first thing I range was a starling at 117yds dialed up what it told me and starling down. I changed the program for the Ghost for his tune with the JSB MRD pellets and ranged 3 differant targets and it was dead on. I only have previous experience with an inexpensive range finder that I had trouble ranging small thing at distance and did not have very good glass, so far I think the glass is much better than I have used before and am very happy with how it has worked for me.
