The BARSKA Gladiator 20-140x80 Zoom Binocular and Tripod Adaptor Bundle offers powerful zoom magnification for long-distance observation paired with stable tripod mounting capability. The Gladiator binoculars feature a variable 20-140x magnification range to scan wide landscapes and zoom in on details. The large 80mm objective lenses maximize light transmission for crisp viewing in low light. BAK-4 prisms and multi-coated optics ensure optimal clarity and brightness across the entire zoom range. A zoom lever allows quick magnification adjustments without taking your eyes off the subject. For shake-free viewing, the binoculars have a built-in tripod mount that pairs with the included Tripod Adaptor. The Adaptor securely holds the binoculars to tripods or mounts sold separately. Together, the Gladiator binoculars and Tripod Adaptor provide the enhanced zoom magnification and hands-free stability ideal for terrestrial nature watching, birding, hunting, and astronomy.
