Barska 15-45x60 Naturescape ED Glass Waterproof Straight Spotting Scope with Tripod

The Barska 15 - 45 x 60 Naturescape ED Glass Waterproof Straight Spotting Scope takes spotting scope optics to a higher level. Phase coated Porro prisms and fully multi-coated premium ED (Extra Low Dispersion) glass provide you with views of exceptional clarity and resolution. Phase coating results in maximum resolution and optical quality by correcting or "phase shifting" the light that is reflected off the prisms and optimizing it for the scope's aperture size.

Compared to conventional achromatic lenses, ED glass lenses minimize chromatic aberration and other forms of distortion resulting in higher resolution and contrast. 100% waterproof and fogproof, Naturescape ED spotters are at home in the most demanding environments and are ruggedly built to withstand the effects of movement from one location to another.
