Best Outdoor Binoculars For Your Next Adventure

At Sherpa we have a great range of Atka binoculars built for the outdoors. Whether you are an avid bird watcher, checking the surf or spying on your neighbours we've got a pair of binoculars for everyone and every activity. Great for hiking, camping and exploring the outdoors Atka binoculars come with precision adjustments for clear long distance vision.

Things to consider:

  • Magnification

High magnification means you will be able to see further but not necessarily clearer. Most people assume that higher magnification means better binoculars however what people don't consider is that when using binoculars every slight shake of your hands is also magnified as much as the image is. So a higher magnification can lead to a less crisp image. To prevent image shakiness, it is recommended to use binoculars with either 8x or 10x magnification. You will then be able to enjoy a crisp, stable image and see your subjects in excellent detail from both near and far.

  • Lens Size

Bigger lenses mean more light coming in which means a brighter image. Binoculars with a bigger lens will also work better in low light settings such as dawn, dusk and overcast weather. The lens size will however always affect the weight and size of the Binoculars - a smaller lens size will mean a lighter, more compact pair of Binoculars.

  • Exit Pupil

The exit pupil measurement refers to the width of the beam of light leaving the eyepiece. The larger the exit pupil, the brighter the image will be under low-light conditions. Lens diameter divided by magnification gives you the exit pupil. An exit pupil of 7mm gives maximum light to the dilated eye and is ideal for use in twilight and dark conditions.

  • Eye Relief

Eye relief refers to the distance in mm between your eye and the binocular spotting scope eyepiece that allows the full field of view to be comfortably observed. Your eye should be positioned here to see full field of view in binoculars. This should be at least 10mm, 15mm for the best comfort (higher if you wear eyeglasses).

  • Weight & Size

The size and weight of binoculars is largely dictated by the lens size as mentioned above. Smaller more compact bincoluars are best for hiking and travel. Higher quality binoculars with a larger lens are best for viewing from the car when you want more precision images.
