I have a Leupold RX-1000 TBR. Used it for 2 seasons. It has performed as advertised. It is amazing how compact rangefinders have become over the years and more feature laden. Leica is top notch but I am just a casual, seasonal, weekend hunter. I have Leupold scopes on my hunting rifles and just hard not to go with Leupold. The Leupold is still nearly $400 and few shots are easily made that far or should be made that far. If shooting under 200 yards, don't need a range finder and the vast majority of shots are under that. Didn't think I needed to buy one. However, had a weak moment with some discounts in my hand and bought one. I did a 430 yard shot this year that I would not have done without the rangefinder. 0 wind. My gun was really on at 200 yards where I sight it in. You need to know your ballistics for those longer shots and I write them down on paper under my flip up scope lense cap for reference if I need them. Nice 5x5 buck. I would have definitely passed on that shot in prior years. Get a rangefinder that has more range than you will shoot. A 1000 yards on my Leupold is under ideal conditions with a big reflective target. It picks up small trees easily at 500 yards. I would get a finder rated for at least 750 yards, knowing the practical range on a small target will be half that.
Range finders are also nice for target practice. Set up target, walk back until you find the right distance and set up the table.
