Portable Telescopes With A Field Of View Of 2000 Meters

Binoculars advertised with a "field of view of 2000 meters" are typically compact, high-magnification models featuring coated optics, durable construction, and portability for outdoor use. It is important to note that the stated 2000m field of view is often a marketing figure for the total viewing range or a wide field (e.g., 66m/3000m or 2000m range), rather than the standard "meters of width at 1000 meters distance" field of view measurement used by high-end brands (e.g., the Swarovski EL 8x42 offers 140m at 1000m

• High Definition & Magnification: These models often feature high power, such as 40x or 50x magnification, paired with relatively small objective lenses (around 22mm or 25mm) for a powerful zoom in a compact form factor.
• Optics: They utilize BAK4 prisms and FMC (Fully Multi-Coated) lenses to enhance light transmission, image brightness, clarity, and contrast.
• Portability: A key selling point is their compact and foldable design, making them lightweight and easy to carry in a backpack or pocket, often weighing less than a cell phone.
• Durability: They are often described as waterproof and fog-resistant (e.g., IPX4 or IPX5 levels of water resistance) and feature a rubber armor coating for shock resistance and a secure, non-slip grip.
• Ease of Use: Features include a central focus knob and right eyepiece diopter adjustment for precise and easy focusing, along with adjustable eyecups suitable for users with or without glasses.
• Low Light Vision: While not for complete darkness, the optics provide clear vision in low light conditions, such as at dawn or dusk.
• Versatility: These binoculars are marketed for a wide range of activities, including bird watching, hunting, camping, hiking, travel, sporting events, and concerts.
