How to use

Use the central focus wheel to bring objects into sharp focus, and set the diopter adjustment for any difference between your eyes. For best results in low-contrast scenes, allow your eyes a short moment to adapt and steady your stance or rest the binoculars on a stable surface when possible.

Store in a protective case when not in use, keep lenses clean with a soft brush or lens cloth, and avoid touching the glass surfaces directly.
