Advantages
The instrument combines a moderate 7× magnification with large 50 mm objectives to ensure good light collection and easy target acquisition.

How to use
Hold the binoculars steady with both hands, adjust the interpupillary distance to align the two images, and set the central focus wheel until the view is sharp. If present, use the dioptre adjustment on one eyepiece to fine-tune focus for differences between your eyes. For best results in low light, use the 7× magnification to maintain a bright image and a stable view without a tripod. After exposure to spray or rain, wipe external surfaces with a soft cloth and allow the binoculars to dry before storing.
Usage recommendations
Use a secure neck strap or harness when aboard vessels to prevent accidental drops. Store the binoculars in a dry, ventilated place and avoid prolonged immersion. Clean lenses with a soft brush or lens cloth and avoid touching optical surfaces with fingers.
