Light intensity is listed as 17.64 and twilight factor as 20.49. The first describes how much light the pair delivers to your eye. The second is the number that predicts how much detail you will actually resolve at dusk, when most animals move.\u003c\/p\u003e\n\u003ch3\u003eWhat the 10x42mm figures translate to\u003c\/h3\u003e\n\u003cp\u003eA higher twilight factor means more usable detail in poor light, which is why 42 millimetre objectives paired with 10x magnification remains a standard choice for early morning and late afternoon observation. The field of view is 101 metres at 1000 metres, or 5.77 degrees, which is the trade you accept for the extra reach that 10x provides over the more common 8x.\u003c\/p\u003e\n\u003ch3\u003eFocusing, mounting and storage\u003c\/h3\u003e\n\u003cp\u003eFocus runs through a central wheel with a separate diopter setting so each eye can be corrected independently. Twist up eye cups suit eyeglass wearers, and a tripod adapter thread is fitted for long sessions where holding 710 grams steady stops being realistic. The body is BaK-4 prism glass with multi coated optics in a rubber and plastic armoured housing, supplied with dust caps for both eyepieces and objectives and a case for carrying.\u003c\/p\u003e\n\u003cp\u003eFull features and the complete specification table appear below.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e10-fold magnification\u003c\/li\u003e\n\u003cli\u003eSolid, waterproof body\u003c\/li\u003e\n\u003cli\u003eHigh contrast and true colour image\u003c\/li\u003e\n\u003cli\u003eSafely stored and easy to carry in included case\u003c\/li\u003e\n\u003cli\u003eSuitable for eyeglass wearers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\n\u003ctable\u003e  \n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Design\u003c\/td\u003e\n\u003ctd\u003eRoof\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMagnification\u003c\/td\u003e\n\u003ctd\u003e10x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMirror\/Lens Diameter\u003c\/td\u003e\n\u003ctd\u003e42 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial Prismn\u003c\/td\u003e\n\u003ctd\u003eBaK-4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType Of Coating\u003c\/td\u003e\n\u003ctd\u003eMulti coated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEyepieces For Eyeglass Wearers\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiopter Setting\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField Of View At 1000m\u003c\/td\u003e\n\u003ctd\u003e101 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField Of View\u003c\/td\u003e\n\u003ctd\u003e5.77 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Intensity\u003c\/td\u003e\n\u003ctd\u003e17.64\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTwilight Factor\u003c\/td\u003e\n\u003ctd\u003e20.49\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWaterproof\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTripod Adapter Thread\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocusing System\u003c\/td\u003e\n\u003ctd\u003eCentral focus wheel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEye Cups\u003c\/td\u003e\n\u003ctd\u003eTwistUp eye cups\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterpupilar Distance Min\u003c\/td\u003e\n\u003ctd\u003e73.72 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterpupilar Distance Max\u003c\/td\u003e\n\u003ctd\u003e73.72 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Armouring\u003c\/td\u003e\n\u003ctd\u003eRubber\/Plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDust Protection Caps\u003c\/td\u003e\n\u003ctd\u003eDust caps for eyepiece and objective\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight (Without Access.)\u003c\/td\u003e\n\u003ctd\u003e710 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"NATIONAL GEOGRAPHIC","offers":[{"title":"Default Title","offer_id":50239249219824,"sku":"15907","price":2552.0,"currency_code":"ZAR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/2651\/0008\/files\/01_national_geograhic_10x42mm_waterproof_binocular_-_black_front_side_view.jpg?v=1787812819","url":"https:\/\/neonsales.co.za\/products\/national-geographic-10x42-waterproof-binoculars","provider":"NeonSales","version":"1.0","type":"link"}
