Re: Range finders?
I believe you can find the manual on their site. The unit uses the G7 ballistic software, the same as can be found here on LRH. Input your data and when you range a target it measures air density, elevation, and angle and gives you a solution based your data along with the atmospheric conditions. There are a few modes available to express the range. You can get a line of sight range, corrected range, and a MOA correction. My preferences give me LOS followed in just a couple seconds by MOA.
It also has 4 different brightness settings, a quick adjust diopter, and a focus ring. I think I get better clarity and resolution of distant targets than I did with my Leica.
You can also input 5 different sets of data for different rifles or loads.
I was looking at a Vectronix unit along with an electronic weather station and a PDA with ballistic software. More expense and a lot more time and messing around getting corrections. The G7 is rated to give corrections out to 1400 yds, and from there out to 2K it gives LOS.
