Levenhuk Nelson 8x42 Monocular with Reticle and Compass
Marine monocular. Magnification: 8x. Objective lens diameter: 42mm
8 - The magnification ratio indicates the degree of proximity of an object.
42 - The lens diameter refers to the size of the front lens of the device in millimeters. The larger the aperture is, the less sensitive the device will be to external light.
BaK-4 - What monocular lenses and prisms are made of and what affects the image quality
Levenhuk Nelson 8x42 Marine Monocular is perfect for fans of boating, fishing, and small boat owners. As a compact optical tool, it still provides 8x magnification and its aperture is 42mm. It helps to see even remote objects well. This monocular is also excellent for studying close objects: Its close focus is 3m.
The monocular has a built-in compass and a rangefinder. There is no scale illumination and, therefore, we recommend using a compass during the daytime with sufficient natural light. With the rangefinder, you can apply a special formula to calculate the distance to an object whose size is known or to calculate the size (height) of an object at a known distance.
The arc scale is visible through the eyepiece of the monocular. The compass determines the direction to the object in degrees. The division value is 1°. North is 360°, South is 180°, East is 90°, and West is 270°.
The optics are made of high-quality BaK-4 glass. The lenses are fully multi-coated, providing a high-quality, bright image even in bad weather. The sealed body of the monocular is made of plastic. It is filled with nitrogen to prevent the lenses from fogging.
This monocular provides a wide field of view of 120m at a 1000m distance. A wide range of diopter adjustment options is available.
We recommend using this monocular with the Levenhuk FS10 Floating Strap near water: the bright accessory will prevent the optical tool from sinking or getting lost.
