Previously we have favorably reviewed Vanguard's Spirit 1042 binoculars . The Spirit is Vanguard's mid-range offering, while the Endeavor ED is their top of the line offering. Vanguard is better known in the photography accessory market, but with the Endeavor ED series of binoculars they are making a strong push into the hunting and outdoor optics market.
Our review model weighs in at 26.8 ounces and has a magnification of 10.5 with an objective lens size of 45mm. While the weight is on par with other models on the market (and probably as light as you want to go in a 10 power bino anyway) the slight objective and magnification increase is a nice bonus. Most mid-sized hunting binos are offered in a 10x42, 8x42, or 12x42 model with little variation other than going to perhaps a 50mm or 32mm objective.

As we noted in the Spirit review, Vanguard does a good job with rubberizing the exterior of the binoculars. The Endeavor ED is comfortable to hold and the rubber coating extends around the objective lens to offer some protection in the event of an accidental drop.
Rotating eyecups are standard on nearly all binocular models these days. However the Endeavor ED takes it a bit further by offering three noticeable "notched" positions when rotating the eyecups outward. This eliminates some of the guesswork if you like your eyecups set a certain height.

The Endeavor ED also has a locking diopter. This seems like a minor feature unless you find yourself regularly lending your binos to others in your hunting group. Being able to quickly return the diopter to a known good setting for your eyes and then lock it in is a simple but handy feature.

The Endeavor is broken into two groups, the standard Endeavor and the Endeavor ED. Only the ED model uses extra-low dispersion (ED) glass. Previous readers might remember that we covered ED glass in the course of reviewing the Nikon Monarch line of rifle scopes.
ED glass homogenizes the bending of light by wavelength. For example, with ED glass the color red gets bent at the same (or nearly the same) angle as the color blue or any other color in the visible spectrum. This optical trick results in a sharper image with more contrast. Our review model was sharper, brighter, and seemed to offer better color reproduction than a similar model in 10x42mm without ED glass.
Like the Spirit binoculars, Vanguard offers a limited lifetime warranty on the Endeavor ED line. Our review model had no defects so we were not able to test the warranty.
The only downside to the Endeavor ED seems to be the lack of attached objective lens covers. The Endeavor ED ships with a carrying case, bino strap, eye and objective lens covers. However the objective lens covers do not attach to the main body of the binoculars, which is unfortunate, since if they are not attached they easily get lost.
The Endeavor ED includes eye and objective lens covers. Unfortunately the objective lens
covers do not permanently attach to the body of the binoculars.
In conclusion, for those that appreciate contrast and sharpness of the image, the ED glass offers clear advantages over non-ED models. Combine the sharp image quality with good ergonomics, three position rotating eyecups, and a locking diopter makes the Endeavor ED a solid buy at the street price of $399.
