Opticron's 8x21 Explorer Binoculars give you a versatile and capable optic that easily fits in the palm of your hand. Their anti-reflection multicoated optics and reflective-coated roof prisms produce bright and clear images with increased contrast and true color rendition. The lightweight housing is made to withstand use in rain showers and the rubberized armor offers protection from impacts and drops while providing a slip-resistant grip. A closed-bridge design gives the Explorer a solid feel in the hand, while the knurled focus wheel enables easy focusing with either hand. Twist-up eyecups makes it easy and comfortable to use with or without eye wear.
