How to use

Hold the binoculars to your eyes and adjust the central focus until the image is sharp. Use the diopter adjustment, if provided, to compensate for differences between your eyes. For steady viewing at higher magnification, support your arms against your body or use a stable surface. After use, store the binoculars in a protective case to avoid dust and scratches.

Recommendations

For best results in low-light conditions, use these binoculars during daylight or at well-lit events due to the relatively small 21 mm objective and 2.3 mm exit pupil. Regularly clean the fully multi-coated lenses with a soft brush and lens cloth to maintain image clarity.
