The name MONARCH has always been synonymous with optical excellence. The MONARCH M7 10x42 binoculars take that performance to a new level, pushing resolution, brightness and field of view even further. Large 42mm objective lenses with 10x magnification deliver a vast field of view. An incredible Nikon optical system with ED glass and multilayer lens and prism coatings produces outstanding low-light capabilities, lifelike colors and extreme resolution at any distance. Long eye relief with turn-and-slide eyecups for easy adjustments, a locking diopter, a new oil and water repellent lens coating plus a waterproof, fogproof rubber-armored design and more make this next generation worthy of the MONARCH name.
