The lens as well as the prism is effectively coated to reduce the loss of light and halation. Authentic binoculars that demonstrate outstanding power outdoors.TOUGH BINOCULARS THAT DEMONSTRATE THEIR POWER OUTDOORSSTRONG BODYThe robust aluminum die-cast body has an elastomer resin exterior that is scratch-resistant and has good grip. Also useful in hard outdoor environments.RELIABLE WATERPROOF SPECIFICATIONSWaterproof design with inert nitrogen gas filling. It is a strong ally even in environments where condensation is likely to occur, such as water movement, sudden descent, and starry sky observation. Meets heavy duty demanded for outdoor use.CLEAR VISIBILITY WITH REDUCED LIGHT LOSS AND HALATIONFULLY MULTI COATThree layers of anti-reflection coating (multi-coating) are applied to all lenses and prism entrance surfaces, greatly reducing light loss.PHASE COAT, HIGH REFLECTION COATA phase coat (phase difference coat) and a highly reflective coat made of a dielectric material are applied to the prism to eliminate halation and loss of light quantity. Effectively use 3 types of coatings that exceed PFM to completely eliminate light loss and halation. You can get a clear and clear field of view not only in bright environment but also in dark environment such as forest observation and astronomical observation. In addition, even in high-contrast scenes such as concerts, you can see clearly from bright to dark areas.WIDE AND SHARP FIELD OF VIEWHigh flatness of the field of view is ensured by adopting a flat design, and a wide image range is realized. A sharp image is formed not only in the center but also near the periphery of the visual field.LARGE-DIAMETER EYEPIECES FOR EASY VIEWING, HIGH-EYEPOINT SPECIFICATIONSLarge-aperture eyepiece, high-eyepoint specifications with an eye relief of 19 mm. In addition, the twist-up mouthpiece makes it easy for the naked eye to peep. Eyes are less likely to get tired even if detailed observations such as fixed-point observation of birds burrows and starry sky are continued for a long time.Specifications:Model: VX14727- Magnification: 10 times- Objective lens effective diameter: 42 mm- Prism material: BaK4- Prism type: Roof prism- Coating: Fully Multi Coat, Phase Coat, High Reflection Coat- Real field of view: 6.2 degrees- Apparent field of view: 56.9 degrees- 1000m vision: 108m- Pupil diameter: 4.2 mm- Brightness: 17.6- Eye relief: 16 mm- Close range: About 1.3m- Luck: 57-75mm- Waterproof: Waterproof with nitrogen gas filling- Tripod mounting: Available- Main accessories: Soft case, neck strap- Size/height x width x thickness:136 x 129 x 53 mm- Weight: 705g
