ED(Extra-low Dispersion) glass is built in SV202 Binocular. ED glass has this unique characteristic and when combined with other glasses minimizes the effects of the secondary spectrum. Comparing to achromatic lenses, and ED glass reduces chromatic aberration to a remarkable degree. So if you would like to observe in low light conditions, such as at dawn or dusk and it is better to use an ED glass Binocular.

BAK4 has a high refractive index and lower critical angle than other materials, which means it transmits light better with less light being lost due to internal reflectionsuch as from internal bubbles trapped during the manufacturing process.

Fully Multi-coated Glass means multiple coatings on all lens surfaces. And all air-to-glass surfaces are anti-reflective multi-layer coated. Fully multi-coated lenses are typical of high-end optics.

100% waterproof internals to handle the most extreme weather conditions, ensuring you can watch uninterrupted views.

Whether you wear glasses or not, you can find the comfortable observation position by adjusting the eyecups.

This SV202 binocular is of low density (about 1.8g/cm3 magnesium alloy, high impact load capacity and high quality magnesium alloy body. So you don’t have to worry about breaking it outdoors.

The diopter adjustment is a control knob on your binocular. It is designed to let you compensate for differences between your own two eyes. Once you set the diopter, then the two barrels should stay in proper relation. From then on you can focus just by turning the central focusing knob.
