The VM/ VMR version of the line also boasts switchable internal filters to enhance viewing experience. Really helpful in foggy conditions, or bright light, they work by polarizing the incoming light or cutting out some of the spectrum (see Details). Changing the viewing modes is as simple as moving a switch on the bottom of the binocular.
The first line of protection against extreme outside conditions – extra durable flat front lenses prevent the inner optics from scratches, dust and moisture.
The only moving part of the body - eyepieces are setting interpupillary distance, while oblique eyecups maximize comfort and cut out peripheral light.
Eclipse-M lens caps remain attached at all times and can protect the front optics from distortion due to precipitation.
