The 8-24x50 Gladiator Zoom Binoculars from Barska are designed for long distance terrestrial and astronomical viewing. The versatile 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. An ergonomically placed zoom lever allows users to make fast magnification changes while viewing through the eyepieces with a simple movement of their right thumb. The large objectives and ruby multi-coatings draw in copious amounts of light to push the low-light capabilities of the optic, while a large exit pupil at low magnification ensures complete coverage of the user's pupil when it gets fully dilated as light fades. Fold-down eyecups enable comfortable viewing with or without eyewear, and rubber armoring provide a slip-resistant grip. 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.
