Explore Scientific - BT-82 SF Giant Binocular

These binoculars are built for rough-and-tough experiences. The IPX6 sealed and nitrogen-filled design offers great protection against fogging of the internal optics, even under rainy and wet weather conditions. The binoculars are protected by a very light magnesium housing that makes them both lightweight and easy to handle.

What's more, these binoculars are fitted with two Explore Scientific 20 mm eyepieces of the 62 degrees LER series! These eyepieces offer an apparent view of 62 degrees and a focal length of 20 mm, allowing the BT-82 binoculars to produce 24x magnification. Therefore, these wide-angle eyepieces offer a field of view of 2.6 degrees at moderate magnification. Paired with a long eye relief of 15 mm and soft silicone eyecups, these eyepieces offer comfortable viewing for both eyeglass wearers and non-eyeglass wearers alike. Due to their waterproof design and argon filling, these eyepieces are ultra-durable and easy to clean as well.
