{"product_id":"3669","title":"Binoculars Praktica Marine Charter 7x50 Blue","description":"\u003cp\u003eThe Praktica Marine Charter 7x50 Blue binoculars are so-called marine binoculars, which have a number of advantages. In addition to complete waterproofing and nitrogen-filled housing, all marine binoculars must have a bright, noticeable housing coloring so that it can be easily detected if dropped in water. At the same time, the straps of such binoculars do not sink. Low magnification allows for a wide field of view, high light intensity, and promotes image stability even when observing from a boat rocking on the water. \u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg alt=\"\" height=\"245\" src=\"https:\/\/sva.kiev.ua\/userfiles\/images\/924169.jpg\" width=\"700\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e     \u003cp\u003eLike many of the world's leading optics manufacturers, Praktica was until recently better known as a manufacturer of high-quality cameras. Founded in 1949 in Dresden, East Germany, the company has produced over 100 different camera models, and continues to receive awards for innovation and product quality. Today, Praktica has expanded its product range, successfully using its many years of experience in developing optical devices, Praktica has taken its rightful place among manufacturers of top-class sports optics.\u003c\/p\u003e     \u003cp\u003eThe main advantage of the Marine Charter 7x50 Blue is its complete moisture and dust protection. The IPX7 waterproof class provides water protection at a depth of 1 meter for half an hour. A wide and comfortable strap will stay on the surface of the water, preventing the binoculars from completely submerging. Internal filling of the housing with nitrogen prevents fogging of the optics from the inside and internal corrosion.\u003c\/p\u003e     \u003cp\u003eThe binoculars have a fairly massive body for installing large Porro prisms, but weigh only 1 kilogram, being one of the lightest in its class. Large prisms in combination with wide-angle eyepieces provide a wide field of view, stereoscopic images, and do not cut off the light beam. Full multi-layer enlightenment in green and violet tones has a high intensity and contributes to maximum light transmission.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003e \u003cstrong\u003eOptical characteristics:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e Magnification: 7x\u003c\/li\u003e\n\u003cli\u003e Lens diameter, mm: 50\u003c\/li\u003e    \u003cli\u003eExit pupil size, mm: 7.14\u003c\/li\u003e\n\u003cli\u003e Pupil relief, mm: 23\u003c\/li\u003e\n\u003cli\u003e Twilight Factor: 18.71\u003c\/li\u003e\n\u003cli\u003e Aperture: 50.98\u003c\/li\u003e\n\u003cli\u003e Minimum focusing distance, m: 6\u003c\/li\u003e\n\u003cli\u003e Field of view, m\/1000 m: 118\u003c\/li\u003e\n\u003cli\u003e Diopter correction: +5\/-5\u003c\/li\u003e\n\u003cli\u003e Adjustment of the center distance \u003cspan style=\"color: rgb(0, 0, 0); font-family: Arial; line-height: 17px;\"\u003e, mm: 56-74\u003c\/span\u003e\n\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003e \u003cstrong\u003eDesign features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e Optical design: Porro prism\u003c\/li\u003e\n\u003cli\u003e Lenses: Fully Multi coated\u003c\/li\u003e\n\u003cli\u003e Prisms: BAK-4\u003c\/li\u003e\n\u003cli\u003e Water Resistance: 100% Waterproof Case\u003c\/li\u003e\n\u003cli\u003e Anti-fog protection: thanks to hermetic sealing and nitrogen filling of the housing\u003c\/li\u003e    \u003cli\u003eFocusing: central wheel and diopter correction ring\u003c\/li\u003e\n\u003cli\u003e Eyecups: \u003cspan style=\"color: rgb(0, 0, 0); font-family: Arial; line-height: 17px;\"\u003eFold Down type\u003c\/span\u003e\n\n\u003c\/li\u003e\n\u003cli\u003e Body: polycarbonate with non-slip rubber coating\u003c\/li\u003e\n\u003cli\u003e Socket for mounting a tripod adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003e \u003cstrong\u003eEquipment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e Binoculars: body color - blue\u003c\/li\u003e\n\u003cli\u003e Protective lens caps that snap onto lenses\u003c\/li\u003e\n\u003cli\u003e Protective eyepiece covers\u003c\/li\u003e\n\u003cli\u003e Wide non-sinking shoulder strap\u003c\/li\u003e\n\u003cli\u003e Storage and transportation case\u003c\/li\u003e\n\u003cli\u003e Lens cleaning cloth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003e \u003cstrong\u003eOverall dimensions, mm:\u003c\/strong\u003e 210x165x87\u003c\/p\u003e     \u003cp\u003e\u003cstrong\u003eWeight, kg:\u003c\/strong\u003e 1.015\u003c\/p\u003e | Manufacturer code: 924169\n Parameters:\n Warranty: 24 months\n Country of brand registration: Germany\n Country of origin: China\n Weight: 1015 g\n Dimensions: 210 x 165 x 87 mm\n Glass type: BAK4\n Delivery set: Binoculars Protective lens caps that snap onto the lenses Protective eyepiece caps Wide non-sinking shoulder strap Storage and transportation case Lens cleaning cloth \nAdditional features: Focusing: central wheel and diopter adjustment on the eyepiece Diopter adjustment range: +5\/-5 Interpupillary distance adjustment, mm: 56-74\n Aperture: 50.98\n Exit pupil diameter: 7.14 mm\n Twilight Factor: 18.71\n Minimum focusing distance: 6 m\n Real angle of view: 6.8°\n Eyepoint Relief: 23mm\n Eyepiece frames: Fold Down type\n Sealed Construction: Water Resistance: 100% Waterproof Case\n Protection: Waterproof Gas-filled Shockproof\n Field of view at 1000 m: 118 m\n Zoom ratio: 7x \nLens diameter: 50 mm\n Construction type: Porro\n Type: Binoculars\n","brand":"Praktica","offers":[{"title":"Default Title","offer_id":41290603659441,"sku":"sva_3669","price":5491.2,"currency_code":"UAH","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0538\/8517\/3937\/products\/14017778968789__5cacfacf73.jpg?v=1650936066","url":"https:\/\/usefulrare.com\/products\/3669","provider":"Dostavka","version":"1.0","type":"link"}
