How to use

Hold the monocular steadily with one or both hands and look through the eyepiece. Adjust the zoom ring to set the magnification between 20× and 60× according to the viewing distance and desired field of view. Use the focus wheel to achieve a sharp image of the subject. For prolonged observation or greater stability at higher magnifications, support your arms on a stable surface or use a compatible tripod or monopod if a mount is available. After use, store the monocular in a protective case and wipe lenses with a soft, lint-free cloth to remove fingerprints or moisture.

Usage recommendations

For best image quality at higher magnifications, select a stable viewing position or use support to reduce hand shake; use lower magnification in low-light conditions to improve brightness and field of view.
