Product Information-Polarizers

Push the polarizer assembly onto the eyepiece until it is seated firmly against the rear face of the eyepiece:

Normally, the unit is aligned so that the tab on the filter carrier and the tab cup on the housing are on the top. On rifles where the bolt lever comes close to the scope eyepiece, the housing/carrier unit can be rotated so the lever will miss the side tabs when operated.

NOTE: Carefully check that you still have sufficient clearance between the polarizer and your face to prevent contact under recoil:

Treat the filter with the same care you would any fine optical surface. Blow grit or dust off the surface of the filter before attempting to clean it. Use lens fluid on a lens tissue or soft cloth.

Glare on the surface of windows, windshields and other transparent surfaces can prevent you from seeing clearly enough to engage targets. A polarizing filter can allow you to see-through this glare, but placing a filter in front of a scope can shift your point of impact. The WSP is designed to mount at the rear of your scope on the eyepiece where it will not change point of impact. You can demonstrate the glare reducing effect while the filter is off the scope. Simply look through the filter at a windshield or window. Slowly rotate the filter, and at two angles (180° apart), the glare from the surface will be substantially reduced. Please note that if the sun is directly behind your position, the glare reduction effect will be minimal. When looking through tempered or laminated glass, you may notice a rainbow or pattern effect. This is the polarized light revealing stress patterns in the glass.

While looking through filter, slowly rotate it until surface glare is minimized. If not needed, the polarizer can be moved out of the way. First, pull the filter carrier back out of the housing. Then flip the filter carrier forward, rotating it through 180°. Finally, slip the filter carrier up onto the top of the scope so that the tab seats into the tab cup. This will hold the filter up and out of the way, even under recoil.
