General information

Marine, reliable and sturdy, Levenhuk Nelson binoculars produce a perfect flat image and are a perfect choice for people who like to travel a lot, 
especially on the water, and often find themselves in extreme situations and harsh conditions, where regular binoculars just would not do. The

and sea waves.

Waterproof shells (IPX7), embossed for the perfect grip;

Eyecups made of soft rubber;

Individual focusing and diopter adjustment mechanisms;

Built-in compass with diode light for easy orienting in any light conditions;

Rangefinder scale for convenient measuring of the observed object’s size or distance to the object;

Adaptable to a tripod (purchased separately).

The kit includes: Levenhuk Nelson binoculars, dust caps for eyepieces and objective lenses, strap, pouch and optics cleaning wipe, batteries, 
user manual and warranty.
Focusing and diopter adjustment

Your left eye vision might be different from that of your right eye and you might need to adjust the diopter settings and focus the image. The 
focusing is individual, which is typical for marine binoculars. Each optical tube is focused independently.
Follow this procedure to adjust focus and diopter setting:

Set right and left eyepiece to zero.

Look through the binoculars at an object about 100 meters away.

Close your right eye and rotate the left focusing wheel until the view is focused in the left eyepiece; then, do similarly for the left eye and
right eyepiece.

The binoculars are now adjusted to your eyesight. Note the diopter adjustment for further reference. 
Interpupillary distance adjustment

Look through the binoculars’ eyepieces with both eyes. To adjust the interpupillary distance, keep varying the angle between the binoculars’ 
parts (relative to its central axis) until the image merges into a single circle. Remember the setting for future use.
