Bynolyt Butterfly MC 10x30
This compact Bynolyt Butterfly MC 10x30 viewer has an additional feature, called a long eye relief which allows you to see the full field of view even if your eyes are far away from the eyepiece. This is particularly useful for eyeglass wearers as well. In addition, the eye rubbers can be folded.
Additional information
The viewer is comfortable to hold because of a balanced weight distribution and the plastic housing, which is pleasantly warm to touch. The Butterfly provides a bright contrast-rich image and is an asset for anyone who wishes to pay a small price for compact binoculars.
