STM 80 HD W/ 25-50x Eyepiece
Product Description
STM 80 HD
Extremely rugged and unusually lightweight spotting scopes thanks to state of the art magnesium technology.
The large objective lens diameter enables observation in razor-sharp detail due to excellent light-gathering qualities even at high magnifications.
Fluoride-containing HD lenses minimize color fringing (chromatic aberration) and deliver high contrast images with razor-sharp outlines. Ideal for digital photography through the spotting scope.
A straight scope simplifies locating the target.
