The new 30mm Monarch HG series follows in the footsteps of its award-winning 42mm siblings in delivering top-of-the-line optical performance, unmatched strength and exceptional handling. Designed to maintain performance. Specifications of the original 8x42 and 10x42 models, the new Monarch Hg 30mm binoculars do so in a smaller size and nearly 8 ounces of weight reduction. The MONARCH HG's optical system is designed around its ED (extra-low dispersion) glass and high-quality multi-layer coating that is applied to all lenses and prisms for brighter, higher resolution viewing. Nikon's field-flattening lens system works in conjunction with the extraordinarily wide 30mm MONARCH HG field of view of 8.3 degrees and 6.9 degrees respectively on the 8x30 and 10x30 models to provide unparalleled vision. Sharp and clear lens periphery. The new Monarch HG 8 x 30 and 10 x 30 are constructed with a body made of magnesium alloy, providing optimal strength, impact resistance and weight reduction. To ensure long-term optical acuity, all Monarch HG objectives and eyepiece lenses are protected by scratch-resistant coatings, while the inner lenses are protected from fogging with an extreme waterproof rating that ensures fog-proof integrity even at altitudes of 16,000 feet equivalent. To maintain your personal diopter settings, Monarch HG binoculars feature a locking diopter adjustment ring. Lift up to adjust, push down to lock.
