Well, I used the old leupold 800 tbr for 4 years I believe. The display started going bad on me this year when the numbers started to fade. I got great readings with it, but it wouldn't range deer past 400. I sent that rangefinder in with an explanation what was going wrong and never hear a peep from Leupold. Earlier this week, a brand new rx 800i TBR showed up at the door. No bill or anything. That impressed me a lot... especially since the rangefinder was a few years old. Anyway, I haven't had a chance to test this new one, but the old one worked well with rifle and bow, but needed trees or large rocks to range at long distances. It is a bit cumbersome to setup, but once you set it up you never have to mess with it again. I don't remember the price, but for what I put it through I'd buy it again.
I will say that it doesn't gather light extremely well, but I'm sure thats because of the small lens. Its not real great at ranging through grass, but you will sneak a measurement through there occasionally.
