Understand the Burris is not just a rangefinder built into the scope - I'm fine with that & one day I would like to own a scope/rangefinder in one.

The "Eliminator" calculates the distance based on the ballistics of the cartridge & bullet type you're using, and illuminates a dot as to where you should aim/shoot (too much technology for me).

BTW - It does not calculate for windage however (FYI).
