It began several years ago with a goal to build the best binocular. Take on conventional optics companies and give them something to chase. We searched the world for the highest grade, most advanced glass available and in doing so, became the only manufacturer to use SF glass in a binocular. To protect that vital investment, we engineered a magnesium alloy frame so durable it can withstand our most rigorous tests. Perhaps the most unique development though, is the Variable Speed Focus System™. This ingenious feature makes other focus wheels feel inferior. Acquire targets from 30 feet out to infinity with a minimal turn of the focus wheel and be shocked by the near focus of just 36 inches. Those building blocks, along with a multitude of other innovations, have taken the Epoch to the pinnacle of optical design and engineering.
