Optical PerformanceModerate 7x magnification helps to produce a wide exit pupil for enhanced low-light use and easier viewing on rough or rolling seasLarge 50mm objective lenses boost light-gathering ability for brighter views in challenging conditions such as at dawn and dusk or in heavy fogTraditional Porro prism light path presents a rich depth of field to more easily discern the relative position of objects within the field of viewBAK4 prisms deliver a round exit pupil and a crisp and clear image with limited edge distortionAnti-reflection multi-coated optics improve light transmission for brighter high-contrast imagesGenerous 378′ field of view at 1000 yardsUse and HandlingLarge slip-resistant center focusing knob is easy to manipulate in cold or wet conditions or while wearing glovesFold-down rubber eyecups contour to the eye socket to block peripheral light from affecting the viewRight-eye dioptric correction allows users to compensate for optical prescriptions for sharper views56-72mm interpupillary adjustment rangeTripod mountable with optional adapterLong 22.7mm eye relief allows the optic to be held away from the face and prevent accidental impacts on rough seas, and to make viewing more comfortable with reduced eyestrainWide 7.1mm exit pupil allows users to enjoy the entire view without vignetting, even on rough seas
