Leupold GR 10-20x40 is a compact observation telescope for tourists and nature lovers , which is characterized by its high detail and image brightness, wide field of view, as well as its lightweight and compact design.Key features of the Golden Ring series:Twilight Light Max monitoring system :Increased twilight efficiency Increases image brightness in low light conditions (approx. 20 minutes),eliminates image blur and stray reflections,premium lenses provide sharp sharpness,increases image depth and contrast.Folded light path technology - thanks to this technology we have been able to reduce the size of the telescope while maintaining a large magnification range. To create a lighter and more compact optic, Leupold uses a mirror system that reflects light as efficiently as possible instead of heavy prisms.Magnesium alloy body - lightweight, solid construction, resistant to mechanical damage.Rubberised eyecup with adjustable height - provides comfortable viewing for users wearing corrective lenses.Xtended Twilight Lens System - optimises transmission of low light waves so you can see dark, low-light scenes in greater, brighter detail than any other available range.100% water and dew resistance - thanks to Leupold's patented nitrogen filling technology, the telescope is fully protected against weather conditions and internal evaporation.DiamondCoat 2 coating - the most abrasion-resistant protective coating available, which also increases light transmission and image contrast.Built-in 1/4-20 tripod socket- ensures quick and convenient installation.Optional reticle* - a grid in the foreground allows for quick and efficient calculation of shot correction (some models).Lightweight and durableThe telescope barrel is made of ultra-light carbon fibre, which is also covered with a rubber coating to ensure a stable and comfortable grip in all conditions.The Leupold GR 10-20 × 40 is a pocket scope rifle scope with an overall length of 191 mm and a low weight of only 447 g. A telescope of this size will be perfect for hiking, outdoor and other applications where carrying comfort is important. The inside of the scope is filled with dry nitrogen , which eliminates the problem of lens fogging.The Leupold waterproofing technology used guarantees 100% resistance to weather conditions , so the telescope can be used in all weather conditions.Excellent image qualityThe optical system uses anti-reflective, multi-coated lenses , which are responsible for high light transmission and reduction of stray light.Thanks to its compact size and light weight, the Leupold GR 10-20×40 is perfect for hiking, nature observation and work uniforms.SPECIFICATIONSFeaturesFeature informationGas refill NitrogenAngular field of view [°] 3.8Linear field of view at 1000 m [m] 66-45Min.
