    Viper HD vs Razor HD 10x42 FOV

    I did side-by-side comparisons with five individuals during bright sunlight hours and at dusk on two occasions with two 8 x 42 and 10 x 42 HD’s and UHD’s. All six of us agreed the UHD was superior in almost every area except FOV. The UHD’s were brighter, sharper and had better resolution on...

    Viper HD vs Razor HD 10x42 FOV

    Absolutely not, the Razor HD is an excellent binocular and fits right in there with all the other $1000 price point choices, imo. I think you said it well, the Viper is imo an exceptional $500 choice. My experience is reflected in the fact I see a good optical bump from the other makers when...

    Viper HD vs Razor HD 10x42 FOV

    I agree with Elkhornsum here, all things being equal the 50 mm will be superior in low light conditions every time. I’d like opine on my experience with the Vortex comparisons. I had the Viper HD, razor HD, and the UHD in 10 x 42 all at the same time for over two weeks. (I also did this...

    Viper HD vs Razor HD 10x42 FOV

    The Razor 10x42 is 6.9 and 362 ft at 1000 yards, one of the largest on the market , and newer 2018 viper is 6.5. The older Viper was 6°, substantially less. Also the 2018 viper version had less CA and was a touch brighter, Very little separates the newer viper to the old Razor HD. Definitely...

    Viper HD vs Razor HD 10x42 FOV

    The warranty and customer service is great. And they have a product for almost everybody, from the least expensive entry-level Binoculars all the way up to the alpha UHD, phenomenal glass. Until I tried and had all three of these side-by-side, I never knew that Vortex UHD line was so good. Paul

    Viper HD vs Razor HD 10x42 FOV

    I believe allbinos has some light transmission numbers on both of these bins. But for some reason what the eyes see and his numbers don’t always line up. I think there was some talk that two different methods were over time with his measuring of transmission, so that would mean some of the old...

    Viper HD vs Razor HD 10x42 FOV

    The 2018 version Viper has a FOV of 6.5 degrees to 6.9 for the Razor, that’s about 20 feet at a 1000 yards. Nothing there in my opinion that would would sway the choice. This is an interesting comparison considering the Razor is twice the price $500 to $1000, but the gap in optical quality is...
