I pretty much agree with 25-06 on the ranging capabilities from my experience and what I've heard . However , I have one word of Warning . These Long Range LRFs are expensive and my experience with their Quality Control is not what I would term "good". When you first get it , go out and Test Repeatibility from a rock solid rest . I used sand bags on the roof of my car . "Shoot" the same objects 10 times in a row . These readings should all be within a few yards of each other ...you might get a very small delta because of slight changes due to finger pressure on the ranging switch even on sand bags . Some of these units require much more finger pressure than I think they should . When you free -hand these , you are kidding yourself if you think you are sighting exactly on one single Target out there . I had to send back 2 Swaros before I got a good one . Try to borrow a friends LRF and compare one versus the other . Also , try them at different Ranges and types of Objects ....Road signs are easy because they are pretty reflective . When you get a good one , treat it gently and don't let it bake in a hot vehicle with closed windows .....car trunks are much cooler than the drivers compartment if both sit in the sun all day .
