Duplex Reticle
A simple crosshair with thick outer posts that taper to thin lines at the center, the fast and uncluttered standard for hunting optics.
The duplex pattern uses heavy bars on the outer portion of each crosshair that step down to fine lines as they approach the center. The thick posts draw the eye quickly toward the middle in low light or under time pressure, while the thin central section still allows a reasonably precise aim point on the target. This is the most common hunting reticle because it gives a clean, fast sight-picture with nothing extra to crowd the view.
What the duplex deliberately lacks is any measuring capability: there are no dots, hashes, or grids for ranging or holding wind. Because it carries no calibrated subtensions, it is almost always built in the second-focal-plane, where the reticle stays a constant visual size as magnification changes. For shooters who dial corrections on the turret rather than hold them in the glass, that simplicity is a feature rather than a limitation.
