You can read them on the product before you take our word for anything.\u003c\/p\u003e\n\n\u003cp\u003eA 5 degree field works out to roughly 87 metres at 1,000 metres, which is how much of a treeline or a far bank you hold in view at once. Dividing the 50 mm objective by the 12x magnification gives a 4.2 mm exit pupil, and that is the beam of light the optic hands your eye. Both figures come off the collar and a calculator, so you can check either one.\u003c\/p\u003e\n\n\u003cp\u003eOn a headland, at a marsh edge or across a valley, \u003cstrong\u003etwelve times magnification also means twelve times your own pulse\u003c\/strong\u003e, which is why the tripod mount and the phone clamp both come in the box.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTwelve times magnification through a 50 mm objective lens brings a distant ridge, bird or boat close enough to identify rather than guess at.\u003c\/li\u003e\n  \u003cli\u003eA fully multi-coated lens, marked as such on the eyepiece collar itself, so the coating is a fact you can read off the product.\u003c\/li\u003e\n  \u003cli\u003eThe 5 degree field of view works out to about 87 metres at 1,000 metres, wide enough to find your subject before you settle on it.\u003c\/li\u003e\n  \u003cli\u003eDividing 50 mm by 12x gives a 4.2 mm exit pupil, which is the figure that governs how the picture holds up as the light drops.\u003c\/li\u003e\n  \u003cli\u003eA rotating eyecup adjusts for eye relief so you can use it with your glasses on or off without losing the edge of the picture.\u003c\/li\u003e\n  \u003cli\u003eA standard tripod socket in the base takes the folding tripod supplied with it, which is what steadies the view at twelve times magnification.\u003c\/li\u003e\n  \u003cli\u003eThe universal smartphone clamp holds a handset against the eyepiece so you can photograph whatever you have just identified.\u003c\/li\u003e\n  \u003cli\u003eArrives with a folding tripod, a phone clamp, a belt pouch, a cleaning cloth and a wrist lanyard, so there is nothing else to buy.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eTwo things we will not claim. The maker states no water resistance rating and no prism type anywhere, so we print neither, whatever the rest of this category does. And a 12x50 is a daylight and dusk instrument, not an astronomy telescope.\u003c\/p\u003e\n\n\u003cp\u003eActivearo makes gear for people who would rather be outside than reading specification sheets. This one puts its specification on the eyepiece so the reading takes a second.\u003c\/p\u003e\n\n\u003cp\u003eIf you want the same 50 mm objective at lower power and a steadier picture, look at our 10x50 Monocular. If you want something that lives in a jacket pocket, look at our 10x25 Compact Monocular.\u003c\/p\u003e","brand":"Activearo","offers":[{"title":"Default Title","offer_id":64561939251549,"sku":"27840935676821","price":38.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/7188\/4893\/files\/1a-182955-flat.png?v=1789040534","url":"https:\/\/activearo.com\/en-gb\/products\/12x50-monocular-telescope-fully-multi-coated-lens-and-phone-adapter","provider":"Activearo","version":"1.0","type":"link"}
