    I got these as a Christmas present to myself and I am not just satisfied with them, I’m thrilled. The clarity of the image, the lack of any distortion, the solid feel in the hand, the performance in low light – they’re just great. Yes, there is a tiny bit of image shaking compared to 8X42 if you’re holding in your hands, but I only ever really notice it when I’m using them for astronomical viewing, and even then, it’s not bad (and, if I really was bothered by it, I could just mount them on a tripod). Definitely doesn’t get in the way during bird watching. My only tiny gripe is that the case is pretty snug – seems like I have to jam the strap in there whenever I put the binocs back. The case itself (and the strap) are high quality. I did a lot of research on the optics and to do any better, I would have had to spend at least 2-3X more, so just go buy them. These rock.

    These Vanguard 8×42 binoculars are absolutely stellar. I actually bought them for taking to concerts, not for the outdoors. Even in very low light, they are sharp as a tack with excellent depth of field. I saw Mark Knopfler at the Beacon Theater, sitting in the nosebleed section — second balcony, high up and right against the wall, easily 300 feet away. With these binoculars I could even tell what chords he was playing on the guitar. I also own the 10×42 model, but that requires a pretty steady hand or a tripod. The 8×42 is a better choice for typical uses. The extendable eye cups are sturdy and comfortable. The focusing wheel is solid and fast, with just the right amount of tension so that you won’t accidentally knock it out of focus. The only thing I could wish for would be a slightly roomier carrying case. The carrying case provided is adequate but requires you to collapse the eye cups and really stuff the neck strap in to be able to zipper the case closed.

    Made very well, but am I the only user that just can’t get rid of blackouts no matter how I set them up?

    Being both a small and big game hunter I needed a versatile, lightweight bino option. The endeavor 10×42 have been absolutely perfect! I’ve used them in the bitter cold of the northern MN whitetail season, Turkey hunting and bird watching and they perform fantastic! Couldn’t be happier!!

    These are by far the best binoculars I have ever owned. I am amazed hy the clarity of the glass. They are also very durable. My daughter has dropped them twice and you would never know it. I have offered them to several others for shooting and hinting and they love them.

    Super produit totalement conforme à l’annonce et à mes attentes! Jumelles digne des plus grandes marques, comparables aux 8×42 kite Bonelli. Un produit d’exception qui mérite d’être acheté et utilisé au quotidien vu ses performances et caractéristiques. Indice crépusculaire plus élevé que les kite bonelli permettant de voir même par temps très couvert et en fin de journée!! Je recommande sans hésiter!!
