Helios Fieldmaster ED85DS 20-60 x 80 ED Dual Speed Waterproof Zoom Spotting Scope


20x-60x Zoom


The new high-end Fieldmaster-ED85DS is perfect for the discerning birdwatcher and nature observer. This refined instrument features a doublet objective lens which provides a highly corrected image and excellent optical performance.

One Exotic ED (Extra-low dispersion) lens element is employed in its construction, which virtually eliminates chromatic aberration and delivers high-fidelity true-colour images. Features high quality BaK-4 Prisms. Optics are fully broadband multi-coated throughout for maximum light transmission and contrast. Features a precision 4:1 ratio dual-speed focuser for 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.

The supplied 7.5-22.5mm zoom eyepiece, constructed from 8 lens elements, provides a generous 20-18mm of eye relief and is suitable for use with or without spectacles. Supplied with quality Stay-on case. Standard tripod bush. 

The Helios Fieldmaster-ED85DS is covered by a 5 year limited warranty.
