Use and Care

Due to their high magnification, the Kaibab® HD 18x56 are designed for use on a tripod or stable support (adapter included), ensuring a sharp, shake-free image during long observation sessions. As with most very high magnification binoculars, slight chromatic aberration may appear in high-contrast scenes (backlighting). Clean the lenses with a microfiber cloth and avoid harsh solvents to preserve the ArmorTek and XR Plus coatings.
