I read an article in one of my rifle magazines. They did a rating on it and found it to be quite useful. It takes in account the baro., temp, humidity, and altitude for you. It also adjusts MOA for your shooting angle. Another feature is that you can load up to ten different calibers from Baretts websight with predetermined information. All you have to do is load it into the BORS system. They are planning on making capable of mounting to other optics like the NF. It also has the ability to read range within a reasonable distance, but it is not perfect and they admit that in the article. If you know the size of the target, you enter that into the BORS. Then you run the reticle the length and width that produces a range that is suppose to be somewhat accuratel. Then you return to your zero, and dial in the elevation which comes up on the display. You still have to factor in wind speed and dial that accordingly. It will NOT read windage or help you dial it. That is what I read and sounds like a pretty stable system one you get the hange of it.
