There are many great binos out there, obviously Steiner, Leupold, Swaroski etc..etc and you can pay top dollar for them. Over many years I've hunted and shot 3D with a pair of 10 x 50 Bruntons, for the money they are top notch as they are warranted well, water and fog proof. They may not be the $1000 variety but for the price, they rival them.

That being said, for IBO you cannot use anything over 8X so, in order to conform I'm another vote for the Nikon Monarch series. Again, for the money, they rival the $1000 ones.
