Optical Performance:
Magnification: The scope provides a zoom range from 20x to 60x, allowing users to observe subjects at varying distances with clarity.  
Objective Lens Diameter: Equipped with an 80mm objective lens, the scope gathers ample light, enhancing image brightness and detail, especially in low-light conditions. 
ED Glass: Incorporates Extra-low Dispersion (ED) glass elements to reduce chromatic aberration, resulting in sharper and more colour-accurate images.  
Coatings: Features fully multicoated optics and dielectric-coated prisms, which improve light transmission, contrast, and overall image quality. 
 
Field of View and Focus:
Field of View: At 1,000 meters, the field of view ranges from 36 meters at 20x magnification to 20 meters at 60x magnification.  
Minimum Focus Distance: Capable of focusing on subjects as close as 5.5 meters, facilitating detailed observation of nearby objects.  
 
Physical Characteristics:
Dimensions: Measures approximately 390mm in length, 180mm in height, and 95mm in width. 
Weight: Weighs around 1,550 grams, making it relatively lightweight for an 80mm spotting scope.  
Body Material: Constructed with a robust yet lightweight polycarbonate body, ensuring durability and ease of transport. 
 
User-Friendly Features:
Dual Focus System: Equipped with dual focus wheels that allow for rapid coarse adjustments and precise fine-tuning, enhancing focusing accuracy at higher magnifications. 
Eye Relief: Offers an eye relief of 19mm, providing comfortable viewing, especially for eyeglass wearers.  
 
Durability and Accessories:
Weatherproofing: The scope is fully waterproof and nitrogen-filled, preventing internal fogging and ensuring reliable performance in various weather conditions.
