Outfitted with the high magnification and wide objectives required by birders, hunters, and outdoor enthusiasts who work at long ranges and in challenging conditions, the Opticron 12x50 Adventurer II WP Binoculars are designed to bring far-off subjects in close while providing extended performance in low light. The body is made using both aluminum and polycarbonate to make them strong and durable, and are designed with a neutral weight distribution that ensures the center of gravity sits naturally in the hand to help prevent arm fatigue.
