Backlight incorporates optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision.  (Note:  This backlight appears soft greyish pink, not "red", and is still in the visible spectrum, so is not compatible with night-vision equipment.)  The NV light is designed for optimal performance in low-light conditions.Weekend shooters and military snipers alike have been calling for a Kestrel Meter with crosswind calculation for years — and the Kestrel 4500 meets that demand completely.
