The Alpen Optics Shasta Ridge 10x36 Porro Prism Binoculars provide 10x magnification and 36mm objective lenses for birdwatching, wildlife observation, hunting, and outdoor activities. Featuring K9 Porro prisms, multicoated optics, and a 9.5-foot close focus distance, these binoculars deliver detailed views of distant and nearby subjects. The large center focusing wheel and twist-up eyecups support comfortable handling and viewing.
10x Magnification with 36mm Objective Lenses
The 10x magnification brings distant subjects closer for detailed observation, while the 36mm objective lenses gather light for clear viewing. A 318-foot field of view at 1000 yards helps users locate and track wildlife and other outdoor subjects.
K9 Porro Prism Optical Design
The K9 Porro prism system provides enhanced depth perception and helps distinguish distances between objects. This optical design supports detailed observation of wildlife, landscapes, and natural surroundings.
Antireflection Multicoated Optics
Multicoated lenses reduce reflections and glare while improving image brightness, contrast, and color accuracy. These coatings help maintain clear views across different outdoor lighting conditions.
9.5-Foot Close Focus Distance
The 9.5-foot minimum focusing distance allows detailed observation of nearby subjects such as birds, butterflies, insects, and plants. This feature provides flexibility for both close-range and distant viewing.
Adjustable Focus and Comfortable Eyecups
A large slip-resistant center focusing wheel allows easy adjustments, even when wearing gloves. The right-eye diopter adjustment helps compensate for differences in eyesight, while twist-up rubber eyecups accommodate users with or without eyeglasses.
Tripod Mounting Compatibility
The binoculars support tripod mounting with an optional adapter for hands-free observation. This helps reduce image movement and arm fatigue during extended viewing sessions.
