In this section you will find a selection of binoculars, headlamps and related observation tools.

Question: What do those binocular numbers mean? Most binoculars are described using two numbers, such as 8 x 21. The first numeral refers to the magnification, or power. An object seen through the binocular will be magnified eight times the size when viewed by the naked eye. The second numeral refers to the diameter of the objective lens, which is the end of the binocular facing the object to be viewed. The larger the numeral, the greater the diameter of the lens, and thus the more daylight entering the barrel of the optic to illuminate the object. Binoculars are also described by “field of view.” For example, a field of view of 365 feet at 1000 yards means that when you are viewing objects 1000 yards away, you will have 365 feet of horizon in your field of view. A “zoom” binocular allows you to change the magnification from lower to higher when you are searching for an object. Close-focus monoculars allow you to view everything from an insect on a nearby flower to a bird in the distance. Pocket monocular scopes are small, reasonably priced, and lightweight.
