Silva Eterna Compact Waterproof Binoculars 8 x 25, 10 x 25
Silva Eterna Compact Waterproof Binoculars are completely new binoculars in a novel design with well thought through detail solutions and optical peak performance.
It will be hard for you to find better field binoculars on the market than Silva Eterna Compact.
Silva Eterna Compact Binoculars are designed to withstand really hard use. With an aluminium frame, rubber coating and roof prism they are rugged, compact and lightweight.
Extendable eye relief and adjustable eyepieces make Eterna Compact Binoculars equally well suited for use with or without spectacles.
Opti-Visor, Silva's unique ocular lens shade, can be rotated 360°, thus enabling you to shut out disturbing side-light and reflections of the sun.
The Emerald Fire lens coating eliminates almost all of the harmful UV and IR radiation. The Bak-4 prism and multi-layer anti-reflection coating gives increased light throughput and an amazingly sharp and clear image. A wide field of view and close-up focus limit of approx. 2 metres make Eterna Compact Binoculars the binoculars for unlimited use, from butterfly watching to observing the moon.
