Some of the most exciting moments happen in the magical light of dawn and dusk. MONARCH M5 10x42 binoculars are built for these moments with an ideal balance between 10x magnification and field of view. 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.
