Features 1、Vertical strip anti-skid focusing design, using concave-convex vertical strip anti-skid design, adjust the focus more smoothly, turning left and right back and forth, easy focusing, simple and convenient operation. 2、Using hot stamping technology, it is integrated with the telescope products. 3、Sideways on the back of the thread hanging port, you can string the thread and hang it around your neck, making it more convenient to carry around. 4、Irregular non‑slip concave-convex texture on the lens body to prevent slippery, more stable holding, more convenient to carry out. 5、Multi-layer coating objective lens design, the objective lens is made of 30MM caliber, transparent, reducing light loss, light absorption will be better, and effectively improving light transmission rate. Specification Item type: Binocular Telescope Material: Metal + bronze Color: As picture shown Weight: Approx. 1286g Structure: Binoculars Function type: ordinary telescope Purpose: military telescope Specification: 8X30 Magnification: 8 times Exit pupil diameter: Approx. 3.7mm/0.1in Exit pupil distance: 11.2MM Eye distance adjustment range: 56-74MM Lens level: BAK4 prism Objective lens diameter: Approx. 30mm/1.2in Eyepiece diameter: Approx. 25mm/1in (super large eyepiece) Working temperature: -43~+55℃ Storage temperature: -55~+70℃ Diopter adjustment range: ±4 diopters Reticle grid value: 5mil/grid: Range: 10 grids on top and bottom (50mil) 10 grids on both sides (50mil) Waterproof: nitrogen-filled waterproof Focusing method: left and right eyepieces focusing Frosted shell: NBR shell There are divisions in the 8X30 telescope mirror: Can roughly measure the distance and orientation of the target to you. The scale on the reticle has vertical reticle, horizontal reticle and sight distance reticle. The horizontal division and the vertical division have a cell value of 5 dense bits, and a large cell value of 10 dense cells. The line-of-sight division is designed with the height of the side target being 2 meters. The measuring range is from 400M to 2000M. In the 1000M line-of-sight division, the value of each small grid is 100M, and the value of each large grid is 500M.
