Levenhuk Nelson 7x50 Marinkikare

A marine binocular will be excellent for a fisherman or water sports fan. This high-aperture tool features 7x magnification and a wide field of view that provides for comfortable observing of extended objects. High-aperture 50 mm objective lenses gather a lot of light that allows for observing in the twilight. The shell of these best marine binoculars feature a built-in rangefinder and a compass with diode light. You can see the rangefinder scale in the eyepieces, and you can measure the height of the observed object or the distance to it to determine its location. You need two batteries to power diode light. The compass indicates the direction towards the object. Division value is 1°. North is 360°, South is 180°, East is 90° and West is 270°. The rangefinder serves for calculating the distance to the observed object or its size. You need to know one of these parameters to calculate another one, using a special formula. Place the rangefinder’s indication in this formula. The optical scheme uses Porro prisms. The quality optics made of BaK-4 glass minimize aberrations and transmit a sharp and saturated image. Fully multi-coated lenses significantly reduce light loss. The waterproof shell is made of durable plastic and is rubberized to protect this optical tool from accidental hits. The nitrogen filling prevents the lenses from fogging during abrupt temperature changes. Levenhuk Nelson 8x30 Marine Binoculars comes in a waterproof floating body: if they accidentally plunge into the water, they will not sink, and the lenses and prisms will not be damaged. Add a bright Levenhuk FS10 Floating Strap to go with these binoculars, and they will never get lost! People who wear glasses will appreciate the twist- up eyecups: they will help to set up the width of a field of view correctly. The binoculars’ optical tubes have individual focusing; there is no central focusing mechanism. You can install these best marine binoculars on a tripod for long-term observations to avoid natural trembling of hands. Specifications. Magnification: 7x. Type: Porro.
