The Eterna Compact Binocular from Brunton is a pocket-sized yet durable multi-purpose binocular designed for a wide range of outdoor glassing tasks. Fully multicoated optics and phase-corrected BaK-4 prisms transmit bright images that are as rich in detail as they are in contrast. This model of the Eterna series is configured with 10x magnification, ideal for mid-range applications. The long eye relief, ergonomic composite body armor, and weatherproof construction make the Eterna a full-featured binocular ready for years of adventures.
