Duplex Leupold invented the Duplex Reticle in 1962. Defined by it's heavy posts, which stand out against cover and in twilight conditions, pointing boldly to the intersection. Centering is a snap. The thin crosshairs obscure little. VX-3 models use the Duplex reticle for range estimating as well. If you bracket a deer, you can read the range on the power selector ring.
