Please help me understand binoculars... I will admit, I have always bought cheap wally-world binos and great scopes... at dusk and dawn I looked through the scope albeit a verry poor practice. Anyway, I thought finding the right rifle scope was difficult. Finding the right binoculars is quite confusing: Which is better Porro Prism or Roof Prism? If they have variable power, then why doesnt anyone use them? We choose scopes with it. Is 10x50 good for hunting? I have some areas i want to scope up to 800 yards, and dusk and dawn are super important to me.
