Some of the most exciting moments happen in the magical light of dawn and dusk. MONARCH M5 12x42 binoculars are built for these moments with a generous field of view and the highest magnification power in the series: 12x. Adjustable turn-and-slide eyecups with long eye relief make these the most comfortable MONARCH binoculars yet. Nikon's renowned ED glass reduces chromatic aberration while the dielectric high-reflective multilayer prism coatings ensure superior light transmittance; resulting in brighter images and more natural colors. In addition, phase-corrected coatings are also applied to prism surfaces to increase image resolution. The result? Better, more clear and brighter optics to take your adventure to new heights.
