This model has a classic design and the optical scheme is based on Porro prisms. The optical elements are made of quality BaK-4 glass. The lenses have undergone an FC treatment with numerous layers of anti-reflection coating, which allow the binoculars to offer an image with good contrast and minimal optical aberrations.
The plastic body is airtight and protects the lenses from dust and humidity. The rubber coating of the body provides a secure grip and absorbs accidental shocks. Filling with nitrogen prevents the lenses from fogging. The eyecups, which swivel upwards, provide additional comfort for those who wear glasses.
The Levenhuk Nelson 8x30 marine binoculars feature a waterproof and buoyant body: should they accidentally end up in the water , it would not sink and the prisms and lenses would not be damaged. If you add a brightly colored Levenhuk FS10 neck strap to these binoculars, it will be impossible to miss!
The eyepieces have individual focusing and you need to set each optical tube separately. There is no central focus wheel. The body of the binoculars has a special housing for mounting this optical instrument on a tripod.
A feature of this model is an integrated compass with diode light and a rangefinder. The diode light is battery powered. When looking into the eyepieces, you can see a vertical scale of a rangefinder and a compass dial with a division value of 1°. North is 360°, south is 180°, east is 90° and west is 270°.
You can calculate the distance to the observed object or its size (height) using a rangefinder. It is possible to calculate an unknown parameter with a special formula. Use the rangefinder indications in the formula.
