The Vortex RECCE Pro HD 8x32mm Monocular is the perfect hand-held sighting tool for reconnaissance and range estimation. A generous 32mm objective lens and XR fully multi-coated extra low-dispersion glass lenses make sure plenty of light gets through for a good view - even in low light. Inside the RECCE Pro HD 8x32, Vortex uses a mil based reticle and quick ranging silhouettes assist with range estimation, calling shots, and other reconnaissance work. The large focus wheel is easy to adjust and allows for smooth one handed operation once focused, while the reticle focus keeps your reticle tack sharp. Flared eye cup blocks extraneous light and folds down for use with glasses. Mfg: Vortex Optics
