→ We evaluated each binocular in the following seven categories: Resolution Zavislan: set up a 1951 USAF Resolution Test Chart, as well as several color artifact tests. From 100 yards away, testers recorded values corresponding to detail resolved and color shift perceived. Image Quality: Testers judged each model's image for ease of use, feeling of immersion, clarity, and visual artifacts, including apparent stray light and field curvature. Low-Light Performance: Zavislan took an objective measurement of light transmission, which factors out differences in exit pupil. Build & Ergonomics: He also measured stray light and field of view, and the team judged overall feel in the hand, as well as the quality, feel, and functionality of the casing, focus wheel, eyepieces, diopter adjustment, and lens covers. Weather Resistance: We submersed each binocular in a 5-gallon bucket for 10 minutes, then froze them for an hour, then brought them into the hot sun, rating the effects on image and functionality at three stages during the process. Handling: The lighter and more compact the binocular (relative to its purpose), the better the score. Value: Performance divided by price. We scored each binocular on a 1 to 10 scale for every category and then weighted the results, prioritizing optical performance and weather resistance, for a total possible score of 100. —D.H.
