How to use

For close subjects, bring the binoculars to the minimum comfortable viewing distance and refocus; the compact design supports steady handheld use.

Recommendations

Carry the binoculars in a protective case when not in use to prevent scratches on the fully multi-coated optics. For best results in low light, keep the lenses clean and steady the instrument on a stable support when possible.
