2. Most zoom binoculars are gimmicks, with the required extra glass and adjustment lever contributing little more than weight. But the Brunton Epochs are a serious high-performance tool; they allow you to optimize magnificationfrom 8x to 15xfor the task at hand.
3. A burly but light magnesium-alloy frame keeps the weight of these feature-rich magnifiers at a respectable 32 ounces, while also providing a stout chassis to rebuff the knocks and dings of heavy field use. Oops, backed the Land Rover over your Epochs? The company will resupply anywhere in the world at no charge.
