The ranging accuracy of the GX series of rangefinders is +/- one yard/meter. The
maximum effective range depends upon a number of factors including lighting
conditions and air quality, but the most important factor is the reflectivity of the
target. For most objects, the maximum distance is 600 yards, while for highly
reflective targets, distances of 750 yards can be obtained.
