Let’s start by comparing the parameters of the new binoculars with those of their predecessor, with the help of the following chart . As you see the appearance of both instruments is very similar.

When you take the Viper to your hand, one thing that attracts your attention is the high build quality, fully confirmed in the tests. In such categories as housing, focusing, blackening, collimation, tripod, minimal focus or IPD the Vortex Viper had nearly perfect results.

The binoculars are incredible. The glass is extremely clear producing crisply sharp images. I looked at every binocular I could get my hands on before I bought these and I can say these are comparable or better than some that costed well over 1K. What I love most is the massive sight picture.

These binoculars are similar to pair of Nikon Monarchs I have had for about 5 years, which originally cost somewhat less than the Vipers. I have used the Nikons extensively, and they are great.I have owned a Vortex Razor spotting scope for several years.

Light-weight, Crystal Clear and easy to use. Excellent in low-light too. Highly recommend.

Easy on the eyes I bought the Vortex Viper HD 10x42 Binocular as a Christmas gift for my husband to use when he goes elk hunting. We brought them on our recent trip to Hawaii.

I spent a week comparing my new Vortex viper 10x42 glasses to my 30 year old Bausch and Lomb Elite 8x42 pair. For me, the B and L is the gold standard; I have carried them around the world birding and never regretted it.

Haven't had them out in the field yet, but crystal clear and crisp image through these babies. Can't wait to check em out on the hunt this season.

I was really looking forward to receiving these binoculars after reading all the reviews and comments. I also know someone who loves his Vipers. However, I was very disappointed to find that they are now made in China (as of the end of 2016) and even more disappointed to say they have been...

Our son-in-law is an avid hunter and was thrilled to receive Viper binoculars for Christmas. These came highly recommended by his brothers. He has already used them several times and loves their capabilities.
