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.
