powerful magnification to bring distant subjects up close for
detailed observations. The wide 8-20x variable magnification range

adjustments

housing — making it an ideal companion for outdoor enthusiasts,
sports spectators, and city sightseers alike
Complementing the travel-friendly size are aspherical lenses that
reduce the curvature that can distort the field of view as well as
BK7 reverse Porro prisms that work together to present flat
high-contrast images with lifelike color and consistent
center-to-edge sharpness.
