Review on 🔍 Vortex Optics Viper HD 10x42 Binoculars: Premium Roof Prism Optics for Crystal Clear Viewing by Brad Knierim

These are ordinary cheap binoculars with a higher price. I compared them side-by-side with a pair of Bushnell Bone Collector binoculars I bought for $100 (before the $30 rebate) and the differences between them were so minimal that they were hardly worth mentioning. The vipers were a bit brighter. there was no noticeable difference in image sharpness. Bushnels are best used with goggles as the Viper has a raised rubber ring on the eyepiece that limits how far you can get to the lenses. This makes it impossible to get a nice sharp round image when viewed with glasses. The Viper's diopters easily move in any direction without a noticeable change in focus, then suddenly change sharply once you get to a certain point. this makes them very difficult to set up and after 20 minutes of fiddling I still wasn't sure if I had set them to the best possible position. Bushnell's diopter was very basic. the Bushnells had better definition at the edges of the image and the circle was much sharper. I saw no real difference in clarity between the two as twilight turned to twilight, although the vipers were better at seeing illuminated objects in the distance in total darkness. All in all, for five times the price of the Bushnells, the Vipers are absolutely unimpressive.
