10
The higher the magnification of the binoculars is, the larger the object will be, but the narrower the field of view (FOV) and the darker the image

The larger the aperture is, the more light there will be that enters the optical tube and the image will be brighter, although a larger aperture will increase the size of the binoculars

Description

Introducing Levenhuk Army 10x40 – field binoculars with scales that are great for hunting, extreme tourism, tactical and security purposes, and surveying. The device can be used not only to explore the area and locate distant targets at 10x magnification, but also to make a number of measurements: distances and heights as well as horizontal and vertical angles. It is possible thanks to the scaled reticle and range-finding scale in one of the binoculars' eyepieces.

The optical scheme is based on Porro prisms. All optical surfaces are multi-coated with a special compound that enhances the brightness, contrast, and image clarity. You can focus on the target using a large convenient central focusing wheel. The short close focus limit allows you to see objects on the horizon as well as those just a few steps away equally well. The eyecups, whose position can be adjusted, and the diopter adjustment ring help you adjust the optics to your eyes.

A durable metal body of the Levenhuk Army 10x40 is waterproof and the optical channels are nitrogen-filled to prevent the lenses from fogging up. There is a 1/4" tripod mount.

Key features:

  • Porro prism optics made of fully coated BaK-4 glass
  • Scales in the eyepiece to calculate distance, elevation, and angles
  • Diopter correction and central focusing at a distance of 4 meters (13ft)
  • Nitrogen-filled aluminum alloy body can withstand water immersion
  • Rubberized surface, comfortable handheld observation, and tripod mounting

The kit includes:

  • Binoculars
  • Strap
  • Pouch
  • Eyepiece and objective lens protective caps
  • Cleaning wipe
  • User manual and warranty card
