Svbony SV406P Field Scope 80mm Spotting Scope ED Glass Bird Watching Dual Speed Focus Archery Scope IPX7 Waterproof Target Observation Shooting Bird

【Ultra Low Dispersion (ED) Glass】SV406P field scope is equipped with ultra low dispersion (ED) glass to reduce chromatic aberration, so you can get bright, high resolution and sharp images. The matte thread built into the fuselage effectively eliminates shadows and stray light, making the image clearer and protecting your eyes properly. 【Coaxial Dual Focus】Dual focus system makes focusing easy. Coaxial dual-speed focusing dial helps you quickly achieve and clarify images. Exquisite slow focus wheel for clarity, can save you the effort of focusing, making it faster and easier to focus. 【Removable Eyepiece】SV406P eyepiece interface is a removable standard 1.25 inch interface design, supporting the replacement of various standard 1.25 inch eyepieces. Eyepieces with different focal lengths can be exchanged. [Excellent optical system] Built-in FMC multilayer coating on the high refractive index Bak4 prism transmission surface minimizes chromatic aberration, increases contrast, and provides a bright and natural view. The 80mm large-diameter objective lens with sufficient light-gathering power improves light transmittance even in dark places, resulting in bright, clear, and high-contrast images. [Waterproof & Dustproof] IPX7 nitrogen gas filling makes it completely waterproof, fogproof and dustproof. It has a long service life and performs well in any harsh environment. Suitable for various situations such as bird watching, archery, target shooting, and wildlife observation. This field scope has a powerful zoom magnification of 20x to 60x and a high-quality optical system. Responds to various observation needs. This field scope not only offers wide HD optical zoom vision, but is also highly waterproof and easy to operate. Ideal for target shooting, archery, hunting, bird watching, wildlife watching, hiking, camping, landscape, outdoor sports, astronomical observation, etc. Optical lens made of ED material ED material lenses can actually focus different wavelengths of light to the same point. This significantly reduces color differences, sharpens images, increases contrast, and restores true colors. wide viewing range The 24mm eyepiece of the field scope makes the observation clearly visible, and the multi-layer FMC coating lens effectively reduces the light reflectance and improves the light transmission effect, resulting in high-quality images IPX7 waterproof High-quality waterproof effect allows it to be used in various scenes, such as rainforest or splashing water. Strong watertightness prevents water and dust from entering inside, ensuring long-term use in various complex environments and easy to deal with. removable eyepiece 7-element/4-set lens structure, 20-60x variable zoom eyepiece, interchangeable with other standard 1.25 inch astronomical telescopes (when separated, can be used with 7-21 mm zoom eyepiece). Use with other 1.25 inch eyepieces to greatly improve viewing playability High quality optical system Bak4 prism material eliminates internal light divergence and the image is clearer. The coating is an FMC fully multi-layer coating that increases light incidence for brighter viewing and sharper images. humanized design Telescopic hood that effectively prevents stray light interference Rotating eye mask, easy to operate, easy to use with or without glasses 270 degree adjustable stand base to meet observation needs in different scenarios specification: Objective lens structure: 3 pieces/3 sets Eyepiece diameter: 24mm Eyepiece barrel size: 1.25 inch Zoom eyepiece structure: 7 pieces / 4 sets Prism type: BaK-4 Lens PCS/group: 10 pieces/7 sets Actual field angle (degrees) 2.1°-1.1° Apparent field of view 42°-66° Field of view: 108ft-60ft/1000yds (36m-20m/1000m) Resolution: 2.0" Shortest focal length: 18ft/5.5m Pupil diameter (mm): 4mm-1.33mm Eye relief (mm): 20mm-18mm Lens coating: fully multi-coated Focus system: dual focus mechanism Focus type: Porro prism Nitrogen filling: yes Waterproof: IPX7 Eyecup type: twist up Weight: 1625g / 3.58lb / 57.32oz Dimensions: 405x180x120mm Package includes: 1x SV406P 20-60x80 field scope 1x soft carrying case 1x lens cover 3x PCS eyepiece dust cover 1x cleaning cloth 1x Instruction manual
