The BT Series of binoculars from Explore Scientific are designed for tough outdoor use. The IPX6-rated sealed and nitrogen-filled design effectively prevents fogging of the internal optics, even in difficult weather conditions. The very light magnesium housing saves weight and eases handling.

Large binoculars are effectively a double telescope: each eye has its own complete lens telescope with full light gathering power. These binoculars render objects in a very vivid way, and observing with both eyes is much more relaxing than using just one eyepiece.
