The Shepherd DRS (Dual Reticle System) Scope is the only scope with two independently adjusting reticles which provide visual verification that the proper windage and elevation adjustments have been made. That’s right, you can actually see the reticles move, making it much easier for shooters of any skill level to zero in their scope with only one shot!Each scope has two reticles: the range-finding circles reticle (first focal plane), and the crosshair reticle (second focal plane). Being on the first focal plane allows the range-finding circle reticles to be accurate at every range, regardless of the zoom power. The circles can be adjusted up for flatter shooting rounds or down for rounds with a bit more drop.
The P-Series 3-10x40mm rifle scopes feature Shepherd’s PVD multi-layer coated HD optics which deliver a crystal clear image through the entire field of view.

With the Shepherd Scopes Dual Reticle System, you can actually see the reticles move, so one reticle acts as a point of reference to the other. Zeroing in your DRS Scope is easy:
1. Fire a shot from a solid rest and note where the bullet impacted the target.
2. Hold the crosshairs on the target and rotate the large knobs to move the small zero circle of the front reticle until it is centered on the bullet hole
3. Now turn the small knobs to move the center of the crosshair just above the circles. That’s it, the scope is now zeroed!
