HakwStrike 7X50 Military-Grade Binoculars: Built for Toughness and Precision
Designed and used for Ground Force operations, these binoculars offer reliable performance in all weather conditions. The internal rangefinder enables you to calculate target distances quickly and accurately. The built-in directional compass helps you orientate your position when navigating unfamiliar terrain.
Durability and Performance
The body of these binoculars is built to withstand tough conditions, surviving accidental drops, vehicle run-overs, and even bullet impacts. Nitrogen has been injected into the body, making it waterproof and ensuring clear vision in harsh environments. The BAK4 lenses inside are Fully Multiple Coated, providing extreme clarity in optical performance.
Military-Grade Testing
To meet military requirements, these binoculars undergo rigorous testing. Each pair is tested under high and low temperatures, undergoes a dropping test, and is subjected to a waterproof test to ensure durability and performance.
How Do Rangefinder Reticles Work?
Rangefinder reticles in binoculars and scopes use various systems to calculate distance. One common method involves comparing a scale or measuring marks on the reticle against a known-sized portion of the object you're viewing. This method, known as the Mil-Dot reticle, is widely used in military and hunting applications.
Example:
Imagine you're sailing on a yacht and using your reticle rangefinder binoculars to view a lighthouse that you know to be 60 meters tall.
By using the Mil-dot formula, which involves some simple math, you can calculate the distance to the lighthouse. This formula allows you to determine the distance or size of an object based on known information.
