I like it a lot and it has many useful features. For shorter ranges, it can be used as a rangefinder through subtension. Not much use after 600yds.
Excellent to aid in holdovers, windage adjustments, and size estimations.
For the most part, I use a laser rangefinder and adjust my elevation using the turrent. That is a much more precise way and the only reliable way at long ranges. I want to bullet to hit the kill zone, not somewhere on my target.
I really enjoy using it but it is not a substitute for a range finder and accurate drop tables.
Good luck...
