WORLD-CLASS OPTICS AND HEIGHTENED DURABILITY. With light transmission, clarity and ruggedness as top priorities, we set out to build the ultimate hunting binoculars. The XLT series was born, and this year reborn with a new housing that’s even more durable and comfortable to use. Fully multi-coated optics and BaK-4 prisms work together to deliver ultra-bright, razor-sharp images through the most critical periods of game movement. And the tough, streamlined Dura-Grip Rubber-armored housing is O-ring sealed and nitrogen-purged for 100% waterproof/fogproof dependability. Soft-touch thumbgrips further improve handling ease, and the objective lenses are now protected from the elements by flip covers.
