Levenhuk Nelson overview

  • 1Description

Built with an in-view compass and rangefinder and designed to be buoyant, the Levenhuk 7x50 Nelson Binocular was made to be your constant companion at the beach, in the bay, or out on the high seas.

The power and aperture combination translates to an exceptionally long eye relief and wide exit pupil that help to improve comfort, minimize eye fatigue, and mitigate the disorientation that is common when looking through binoculars on rough or rolling water. Its traditional Porro prism optical path provides a rich depth of field to more easily see the relative distances between objects in your view. Using both passive and active illumination for easy viewing regardless of how much light is present, the compass enables you to take your bearings in all directions, with a reticle and calculation aids that allow you to quickly and easily estimate the distance to, and size of, objects that you're looking at.

To withstand harsh saltwater marine environments, the chassis is made of a plastic that is corrosion and impact resistant, and the optical tubes are nitrogen filled and O-ring sealed to be submersible and fogproof even in extreme weather conditions. The chassis is also made to be buoyant in case the binocular accidentally goes overboard, while the included high-visibility floating neck strap makes it easy to see for a fast water rescue. Tethered objective lens caps and one-piece rainguard ensure they won't be washed away while you're actively using the binocular. For comfortable long-duration use, the Nelson is tripod mountable with an optional adapter to eliminate arm fatigue and minimize vibrations.

Optical Performance
  • Low 7x power magnifies view while maintaining a wide exit pupil and long eye relief
  • Large 50mm objectives ensure bright and clear views in all viewing conditions—especially in low light and under heavy cloud cover
  • Traditional Porro prism light path produces a naturally ergonomic body while providing a rich depth of field to more easily discern the relative distances between two objects in the field of view
  • BAK4 prism glass produces crisp and sharp aberration-free views with a round exit pupil
  • Anti-reflection fully multi-coated optics maximize light transmission to improve image brightness, color rendition, and contrast
  • Two-element/one-group eyepiece lens configuration; three-element/two-group objective lens design
  • 367-foot field of view at 1000 yards
  • In-view compass and reticle let you take bearing readings without removing your eyes from optic
  • Rangefinding reticle allows you to estimate distance, and size of, an object like a buoy or boat
  • Opaque window on top of compass housing illuminates compass during the day to maximize battery life
  • LED compass/reticle illumination in low light when needed; simple push-button activation
  • 360° compass markings at 1° increments; North is 360°, South is 180°, East is 90°, West is 270°
  • Rotating calculation aid on exterior of left optical tube makes estimating distances and sizes of objects faster and easier
  • Runs on two included LR936 batteries
Use and Handling
  • Individually focusing eyepieces enable precision focusing for all users
  • ±5 dioptric focusing range for both eyes
  • 56-76mm interpupillary adjustment range
  • Tripod mountable with optional adapter for hands-free use to reduce vibration and arm fatigue
  • Fold-down rubber eyecups for comfortable use with or without eyewear
  • Exceptional 23mm eye relief reduces eyestrain and maximizes comfort during long glassing sessions
  • Wide 5mm exit pupil will completely cover pupils as they open and dilate in low-light conditions
  • Impact- and corrosion-resistant plastic chassis is ideal for use in harsh conditions such as around saltwater
  • Buoyant body design with high-visibility floating strap makes it easy to retrieve if the binocular goes overboard
  • Nitrogen filled and O-ring sealed for an IPX7-rating to be waterproof and resistant to internal fogging when moving through extreme temperature or environmental conditions
  • Rubber armoring with palm pads protects against impacts while providing a positive slip-resistant grip—especially in cold and wet weather
  • Tethered objective lens caps won't get lost or wash overboard while binocular is in use
  • One-piece ocular rainguard attaches to strap and prevents water from pooling in eyecups in the rain or on rough seas
  • Broad -4 to 131°F (-20 to 55°C) operating temperature range
