The Vanguard Endeavor HD 65A angled view Spotting Scope combines a nitrogen-filled magnesium housing and a fully multi-coated optical path to create a well-equipped zoom optic for intermediate to long-range observation. The Endeavor HD series features an extra-low dispersion (ED) lens system and phase-corrected BaK4 prisms, which maximise light transmission and produce colour faithful images that are rich with contrast.This version of the Endeavor HD spotting scope includes a 15-45x zoom eyepiece featuring a rubber zoom dial. A 1:3 zoom ratio and 2.1-1.0 degree angle of view complement the eyepiece\'s long 19mm eye relief and rubber eyecup, which help to provide additional viewing comfort for long-duration observations.In addition to the image quality and weather-sealed construction, the Endeavor HD includes several features that enhance the scope\'s functionality. A stacked dual-focus mechanism enables the observer to make fine and coarse focus adjustments. The tripod mounting foot has a standard 1/4 inch socket and is compatible with Vanguard tripods that accept the universal mounting shoe. An integrated sunshade and included custom fit raincoat carrying case help to make the Endeavor HD a full-featured spotting scope for outdoor use.Features15-45x Eyepiece Magnification65mm diameter objective lensExtra-Low Dispersion Glass ElementsFully Multicoated OpticsStacked Centre Focus Control, with Fine Focus for delicate adjustmentsAngled View EyepieceNitrogen-Filled Fogproof / WaterproofMagnesium HousingTripod Mounting ShoeRubber Armored BodyRemovable protective coverBuilt-In SunshieldBody can be rotated to allow the eyepeice to be moved to the most comfortble viewing position, for example round 90 degrees for use when lying down SpecificationsAccessories: Protective cover, eyepiece cover and objective lens coverBody Material: Magnesium alloyColour : GreenDiameter of objectives: 65mmEye Cup: Twist outField of View @1000 Yards/Metres: 43.8 - 21mFocus System: Centre focus, with fine focusLens coating: Fully multi coatedMaximum Power: 45xMinimum Power: 15xNear focus: 4.5-5.5mPhase coating: YesRelative Brightness: 18.7~2Type: AngledView Angle: 2.7-1.3 degreesWarranty: 2 YearsWaterproof: YesWeight: 1.45kg
