New to stalking and want to invest in a good set of binoculars. I say invest as I want them to last. Don't know a lot about the technical side but have read up a bit and thought about 8 X 42 as they would probably be better for general use, pigeons, wildfowling etc but let me know if I'm wrong. Other option is 10 X 42. Looked at Leica ultravid, Zeus victory HT and vortex viper which are considerably cheaper. I will gladly pay the asking price for the right piece of kit hence viewing it as an investment. Are Leica, Zeiss and Swarovski that much better and do they justify the price? They also need to be robust, waterproof and fog proof. Any adivce appreciated.
