Viewing Experience: The Vanguard Endeavor ED IV binoculars were among the most expensive in this round of testing, but fell just outside of the “Top Picks” according to our testing. These bins were bright and crisp in the center of the view, with very slight blurring around the edge. When panning, the image was steady and flat. Likewise, the pair rendered backlit objects with minimum color distortion. However, the overall field of color seemed slightly tinted toward yellow or green—resulting in a noticeable difference between the binocular view and the view with naked eyes. This may affect the color perception on birds that are far away. At long distances, they did not render quite the same level of detail as our Top Picks; chickadees and titmice visiting a feeder around 150 meters away were difficult to differentiate. Overall, the bright image, easy adjusting, and solid feel made them an enjoyable pair to have in the field.

Feel and Build: These binoculars are a bit heavier than average (often an indication of higher quality glass) and feel solidly constructed. The smooth focus wheel makes for easy bird finding, though one tester found it could slip out of focus once they were on a bird. The eyecups are a little stiff to adjust, but they hold position and offer four different eye-relief settings. The housing is faintly textured black rubber with an open hinge design that allows your hands to wrap farther around the barrels and can improve the balance. The objective-lens caps fit into a recessed notch in the barrel, so they are less likely to move around or fall off. The neck strap is medium-wide and comfortable, if a bit shorter than average.
