The tripod can be connected to the binoculars through two 1\/4 inch or one 3\/8 inch threaded holes, which are standard photo tripod threads. We suggest using the EXPLORE SCIENTIFIC U-Mount with field tripod (item No. 01-14300) for the best results. This mount is specially designed for the BT series of large binoculars and securely holds these devices. The excellent mechanism of the U-Mount allows for easy movement and tracking, with adjustable friction in both axes. This helps maintain a stable position for the binoculars, depending on the desired level of friction. Thanks to its sturdy construction and large stainless steel tripod, the U-Mount minimizes vibrations and allows for clear observation of even the finest details, even at high magnifications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCA Residents: \u003ca rel=\"noopener\" aria-label=\"Prop 65 WARNING(S) - Opens in a new tab\" href=\"https:\/\/explorescientificusa.com\/pages\/prop65\" target=\"_blank\"\u003eProp 65 WARNING(S)\u003c\/a\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch6\u003eSPECIFICATIONS:\u003c\/h6\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eItem Number\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e01-14210\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eOptical design\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eAchromatic refractor Porro\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eMirror \/ lens diameter\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e82 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eFocal length\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e470 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eFocal ratio\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e5.7\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eApparent Facial field\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e62 degrees\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eType of remuneration\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eEnhanced Multilayer Desposition (EMD)\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eExit pupil min.\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e3.5 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eField of view\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e2.6 degrees\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eWaterproof\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eYes\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eWater resistance protection level\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eIPX6\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eExit pupil distance\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e15 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eTotal length\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e445 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eTotal width\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e226 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eTotal height\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e122 mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eTotal net weight\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003e4300 g\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eHousing material\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cspan class=\"speccell\"\u003eMagnesium\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003ch6\u003eWARRANTY:\u003c\/h6\u003e\n\u003cp\u003eExplore Scientific offers free collimation service for the Giant Binoculars for the lifetime of the product.
