If it’s not broken, don’t fix it, right? Maybe, unless you’re always striving to improve, like our tireless team of designers and engineers. One of our most popular models, the Eterna Mid Size was completely redesigned this year to further its already superb performance features. New for this year, the Mid Size boasts a multi-step eye relief system that allows for comfortable viewing, even with eyeglasses. State-of-the-art multi-coatings give the Mid Size a leg-up on reflective sunlight and are responsible for sharpening edges and protecting colors. The sleek new ergonomic body armor has also been reworked to enhance the appeal for a new generation of Brunton binoculars. 5.4”x4.8”x2”, 25 oz, 4 ft. Close focus, 3.2mm Exit pupil, 15mm Long eye relief, 315 ft. Field of view @ 1000 yds. Limited lifetime warranty.
