Fully multi-coated optical systems deliver the brightest, highest-contrast images with the least amount of eye strain because only a very small percentage of light is lost before it reaches the viewer's eye. Rainguard HD This patented, permanent, water-repellent coating causes moisture from rain, snow, sleet and condensation to bead up and scatter less light, so you get a clear, bright view when other optics would be rendered useless.
