Benefits of Glass Etched Reticles and Illumination
Glass-etched reticles are superior to wire for several reasons, most notable is how much more crisp, fine and clean your view is when you look thorough the scope.
A glass etched reticle, also cannot be broken. Anyone who has shot enough has seen a wire reticle actually break within the reticle field. As the reticle design is etched into the reticle lens, it is static and cannot physically be broken.
All illuminated scopes with glass-etched reticles have the added benefit of zero internal light reflection which occurs to some extent in illuminated scopes with wire reticles.
This superior design requires an additional cost, but even if you don’t plan to use the illumination, the glass-etched reticle is a feature with value to the shooter.
Illumination comes into its own when shooting targets that are either naturally dark or made dark by light conditions such as shadow, dawn dusk, very bright light or night shooting with lamps or night vision kit.
Without Illumination a black reticle can be very hard to make out against the target. Illumination fixes this problem and gives immediate contrast. Adjust intensity according to the light conditions.
Zero Locking and reset target turrets - 1/4 MOA
Push-pull to lock. Loosen the screw to reset. So when you have your sero, lock the turrets to prevent accidental loss of zero if the scope gets knocked about.
Precise 1/4 MOA per click adjustment for fine tuning windage and elevation.

Side Focus Parallax adjustment
Parallax effect is the term that describes the difference in angles between objects that are seen up close and those seen far away. When you look at telephone poles passing by on the side of the road, those closest to your car seem to pass very fast, while the ones far away seem to go very slow. That difference is due to the parallax effect.
The reticle in your scope is like a telephone pole that's very close. If you move your head on the stock while watching the target through the scope the reticle may seem to move, wobble or blur against the target. That affects where you perceive the aim point to be, and that affects your accuracy. Parallax focus correction adjustment reduces this phenomenon to the greatest extent possible.
Parallax focus correction therefore is a must for anyone attempting to use either a high magnification scope, shooting drastically different yardages with the same scope or anyone attempting to shoot at extremely close ranges or extremely long ranges. Especially so if it is a combination of these factors.
