The Sure Shot Night Vision Signal to Noise Booster (S.N.B.) Filter was specifically designed to reduce the noise (sparkle, scintillating, snow etc) that makes it to your eye through your night vision device, giving you a much smoother image. With its purple tint, the S.N.B.filter makes your image color cooler by reducing the green tone which aids in reducing eye strain, helping preserve your natural night vision and reducing backsplash.
Although the S.N.B. filter was designed for night vision devices, the filter also works on any thermal device that utilizes a PVS-14 eyepiece, such as the Trijicon and NVision HALO optics. When ran in tandem with a thermal unit you will notice a lot of the same benefits it produces on night vision such as reduced eye strain, backsplash reduction and better preservation of your natural night vision. By producing a more natural and less pixelated image, you will notice your image is considerably smoother as well.
