The 10-30x60mm Gladiator Zoom Binoculars from Barska are designed for long-distance terrestrial and astronomical viewing. The powerful variable magnification range allows the viewer to scan a large field of view and then zoom in on the selected object to make detailed observations. The large, oversized objectives and ruby multi-coatings draw in copious amounts of light to push the low-light capabilities of the optic beyond smaller optics, while a large exit pupil at low magnification ensures complete coverage of the user's pupil when it gets fully dilated as light fades. An ergonomically placed zoom lever allows users to make fast magnification changes while viewing through the eyepieces with a simple movement of their right index or middle finger. The large objectives add weight to the binoculars; so to reduce arm fatigue from holding them for long-duration glassing sessions, or to keep the binoculars steady at high magnifications, they can be tripod mounted using an optional adapter.
