The Discovery Channel informs, entertains and inspires its audience around the world with the wonders of our planet, its diversity and its surprises. By offering millions of people the chance to make new discoveries and satisfy their curiosity, Discovery provides an engaging mix of storytelling across a range of genres: science and technology, exploration, adventure, history and a behind-the-scenes look at the people, places and organisations that shape the world we live in.
We are proud to present the Discovery range of optical instruments, manufactured by Levenhuk and sponsored by Discovery.
The Discovery Gator 8–20x25 is a variable-magnification zoom binocular. This model has a magnification range from 8x to 20x, making it suitable for a wide variety of situations. The 8x magnification is ideal for watching sporting events and observing birds and wildlife. The 20x magnification allows you to comfortably observe more distant objects, such as the opposite bank of a river, a solitary building in a field, a mountain path, etc.
Although these binoculars feature a Porro-prism optical design, they are still compact and lightweight, making them easy to carry without taking up too much space in your rucksack. The optics of these binoculars, made from BK-7 glass, feature a fully multi-coated anti-reflective treatment for greater contrast and improved brightness. The binoculars feature twist-up eyecups, central focusing and dioptre adjustment. The interpupillary distance can also be adjusted. The eyecups have a twist-up adjustment mechanism.
The body of the binoculars is rubber-armoured, which protects them from moisture and dust.
