The brands we carry at High Point Scientific. The manufacturers listed at any given time during your search refinement offer at least one product that matches other search criteria you have already chosen.
The Binoculars by Type search filter breaks down products in this category so it is easier for you to find what you are looking for. You have a choice to separate binoculars from monoculars, or you can choose to look at types of binocular accessories instead, such as Binocular Tripod Adapters.
The magnification factor, also known as "power", is listed as the first number given in a binocular's name, like 7 x 50, 8 x 40, etc. In the first example, these binoculars magnify an image 7X more than if you were looking at that image with the "naked eye". When talking about zoom binoculars, the magnification is listed like this: 7-21 x 50. That means the binoculars have a zoom mechanism that takes the power from 7X to 21X as far as the eye can see. Please note that it doesn't matter whether there is spacing between the numbers or whether the "X" is upper- or lower-cased.
Don't always assume that more magnification is better! The more power, the harder it is to keep the image stable when hand-holding binoculars. Most people can comfortably hand-hold up to an 8X (most popular for birding), but after that, you may or may not need a tripod for a shake-free view...it depends on your own steadiness and how long you plan to view.
The aperture of a pair of binoculars (or any optical instrument) refers to the diameter of the main optics. Of course, binoculars have two main objectives that are the same size, but the number given for the aperture refers to just one. For instance, 8x50 binoculars have an aperture of 50 mm (and a magnification factor of 8), but unlike a telescope, they have two 50 mm objectives. The larger the aperture, the bigger the binoculars, but more importantly, a larger aperture draws in more light and lets you see more detail in shadow, shade, and other low light conditions.
Use the Binocular Series search filter if you want to check out a particular line of binoculars from a manufacturer. Once you have chosen the Binocular Series, you will see all the models in that series that we offer. A series of binoculars will be very similar in most respects, other than their magnification factor, aperture size and price.
Shopping for binoculars by body size is a great help if you already know you want a pair of compact (small) binoculars or you are looking for large aperture optics for astronomy. In general, the larger the body size the heavier the binoculars will be and the more likely you may need to mount them on a tripod when viewing for any length of time.
