Home Spotting Scopes Helios Spotting Scopes Helios Fieldmaster 20-60x82ED Triplet Waterproof Spotting Scope
The top of the range Fieldmaster-ED82DS triplet is perfect for the most discerning birdwatcher and nature observer. This high-end instrument features a triplet objective lens which provides a highly corrected image and exceptional optical performance, even to the edge of the field. Two Exotic ED (Extra-low dispersion) lens elements are employed in its construction, which virtually eliminates any chromatic aberration, and delivers high-fidelity true-colour images. Features include high quality BaK-4 Prisms. Optics are fully broadband multi-coated throughout for maximum light transmission and contrast. The inclusion of a precision 4:1 ratio dual-speed focuser provides exceptional focusing accuracy. The stylish spotting scope body is constructed from robust but lightweight magnesium alloy, with a sliding dewshield/sun shade.
Fully waterproof and nitrogen-filled for clear, fog-free viewing in all conditions. The supplied 7.5-22.5mm zoom eyepiece, constructed from 8 lens elements, provides a generous 19.5-18mm of eye relief and is suitable for use with or without spectacles.
