I have a Halo XRC model. It is good out to 500 yards which is farther than I am going to shoot. I have it for about 5 years and I have not had any problems with it. I have stood next to people with much more expensive range finders and mine showed the same distance as theirs when we raged things for comparison. I got it from Sportsmans guide. I see they are out of stock but they gave a Halo good for 750yards for a small amount more.
