Bino's are one of the most important tools in your quiver, you'll spend more time using them than any other piece of equipment you carry hunting. When it comes to selecting a pair buy the very best your budget will allow. A bad pair will cause fatigue and eye strain and in the end you'll be inclined to not use them if they bother you eyes. Redfield is part of Leupold now and Leupold is a good American brand, the Japanese make good glass and if your budget allows you can never go wrong with Swarovski or Leica. If you do a side by side test of the expensive stuff compared to the less expensive brands available the difference will be very apparent. A good high end pair of bino's will last a life time so don't be afraid to spend the big bucks and buy the good stuff
