NELSON 7X50 BINOCULARS WITH RETICLE AND LEVENHUK COMPASS (LVN-72109)

The waterproof body reliably protects the lenses from moisture. 7x magnification is sufficient for detailed study of distant objects. The lens with a 50mm aperture collects a significant amount of light, thus offering a bright and sharp image.
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 moisture. 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 turn upwards, provide additional comfort for those who wear glasses.
The eyepieces have individual focus and it is necessary 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.
