I have a conquest hd5. I cant tell much , if any difference in it and a vortex viper or a bushnell elite, for that matter. The Zeiss might be a little clearer at distance at dark than the bushnell elite but i really think the viper is right there with it. The Zeiss is a $1300 scope. Ive been getting the vipers on sale for $400 or less. I think i have about $200 in my elites each. I sure cant see the Zeiss being worth that much more
