The Rampage 20-60x80 Spotting Scope Kit from Redfield is an all-in-one glassing setup that comes with a compact tripod, carrying case with strap, and view-through case that has fold-down objective and eyepiece access that allows the observer to use their scope without removing the case. The Rampage scope has a fully multi-coated optical path that uses BAK4 prism glass and an 80mm objective lens to maximize image brightness and clarity. A 20-60x zoom range and 14-foot close-focus distance make this configuration of the Rampage scope well suited for intermediate- to long-range observations. A nitrogen-filled polycarbonate housing makes the Rampage scope both lightweight and ready to endure the elements. Complementing the durable housing is rubber armoring and slip-resistant ridges that are especially useful when mounting or focusing this optic while wearing winter gloves. Deep knurling on the focus knob's rubber gripping surfaces yields tactile feedback and enhances control. Further enhancing the user-friendly features of the Rampage scope are a twist-up eyecup and a generous 19-17mm eye relief that help to provide a comfortable viewing experience for eyeglass wearers.
