[QUOTE="dennisinaz, post: 601158, member: 40966"] I spent several days wringing this unit out as well. What I saw mirrored what Shawn did with some minor exceptions. Since I didn't have a Vectronix unit to compare to, I just used a Leica 1600. I found it much easier to range a target with the BR2. It was 3 yards different from the Leica at 300, 500 and 800. I don't know which one was correct but found it odd that it was always 3 yards different, rather than a percentage. When the BR2 said 500, the Leica said 497. I was ranging a target backer with no close backstop so I am comfortable on the ranges. I carefully zeroed at 300 to test the ballistic solutions. At first, it was off quite a bit- I discovered that I have put the wrong velocity it. I fixed it and it then agreed with my Shooter software within .2 MOA at any range and mostly was the same. I never got a ballistic solution over 1250 but I just couldn't find the right targets between 1250 and 1400 to test. I got readings out to 2150+ on dark rocks. I never ranged any super reflective targets like the side of a dry van or metal building. It sometimes took several seconds to give a reading so it was pulsing pretty good to get some of those long ones. The beam divergence is not an issue. It ranged everything the Leica did and beyond with matching distances other than the 3 yard issue. The Leica required a dead-steady hold to work. The BR2 was much more forgiving in this area. I used the same battery that Joel had in it when he sent it to me. I can't imagine not getting through a season on a battery. A few issues that I perceived: It is big compared to the Leica or Swarovski. It is rated only down to 32 F. I couldn't test it as it was between 40 and 70 here in Arizona when I ran my tests. It could very well work down to minus 20? I don't know. The lithium batteries are a lot better in cold than the 9 volts. The Leica uses a CR2 lithium which is less than half the storage of the CR123. Most of my testing was done in bright, sunny conditions. I did get out on one cloudy day and that is when I got 2100+. I was only able to get 1900+ at the same spot previously. I could range a horse standing in a pasture at 1100 yards with no problem. I think this unit does what they claim it does. [/QUOTE]
