Pairing a refined optical system with enhanced durability, the 7x50 Marine-3 BIF.GA Binoculars from Opticron feature an enlarged porro prism design with anti-reflective multicoated optics for bright, clear viewing and maintained color fidelity in a variety of lighting conditions. An 18mm eye relief and large depth of field is suitable for an array of users, which further pairs with a nitrogen-filled housing and robust aluminum alloy body for protection when viewing in inclement conditions. Additionally, the 7x magnification and individually focusing eyepieces are well-suited to general viewing of subjects both near and far.
