When competing in long-range shooting competitions the polarizer can help reduce glare on a sunny day and help cut the haze in the rain!
A polarizing filter can allow you to see-through glare, but placing a filter in front of a scope can shift your point of impact. The Polarizer is designed to mount at the rear of your scope on the eyepiece where it will not change the 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.
While looking through the 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.
