A 3:1 zoom ratio is very common in many scope models. It gives you 3 times more magnification at high power than at low power (model magnification ranges are available in powers of 3x: 1.5-5, 2.5-8, 3-9, 3.5-10, etc.), so you can dial power down for close encounters or all of the way up for long-range shots.
High-definition, calcium-fluoride lenses ensure incredible clarity at all magnification levels
Leupold's Custom Dial System (CDS) gives you the ability to customize turret (adjustment dial) to exact ballistics and environmental conditions. Once new custom dial is installed, simply range the target, turn the dial to that number, and aim dead on.
The ZeroStop system creates a backstop when returning the dial back to zero, so you don't accidently turn the dial a full revolution in the wrong direction.
The side focus adjusts the scope's parallax, making the reticle clearer and have less perceived movement when you're shooting at different distances.
The removable, low-profile throw lever makes changing magnifications quick and easy. It includes a thread protector plug to use when the lever is removed.
Leupold pioneered modern waterproof and fogproof technology using advanced internal gasses and sealing methods that withstand extreme temperatures, elevation changes, and shocks, so the internals of the optics stay moisture free and crystal clear for life.
