The Levenhuk Nelson 7x35 marine monocular is fitted with a built-in compass and rangefinder. These features allow the monocular to measure the distance to objects and determine their direction in relation to the cardinal points. The monocular is lightweight and durable, and won’t take up too much space in a rucksack. This instrument is recommended for fishing enthusiasts and owners of small boats.
The monocular offers 7x magnification, which is sufficient for viewing distant objects in detail. The close-focusing distance is just 3 metres. The lenses are made of BaK-4 glass. The fully multi-coated lenses deliver a bright, high-resolution image. The waterproof plastic body is nitrogen-filled, which prevents the lenses from misting up.
The instrument has a built-in compass and rangefinder for daytime use (without illumination). A dial is visible in the eyepiece, showing the direction to the object being observed in degrees of angle. North is at 360°, south is at 180°, east is at 90° and west is at 270°.
The rangefinder will be useful for calculating the distance to an object of known dimensions (height). It is also possible to calculate the size of an object if its distance is known. The rangefinder’s readings and a special formula are all that is needed for the calculation.
We recommend using this monocular with the Levenhuk FS10 floating neck strap when you are near water, as this brightly coloured accessory will prevent the optical instrument from sinking and being lost.
