A distinguishing feature of this generation of binoculars is the innovative eyepiece designed for people wearing glasses. The eye relief has been increased by over 30%. This means that people wearing glasses can enjoy a full field of view. There is also no more awkward folding over of rubber eyecups - these compact binoculars have revolving eyecups that can even be adjusted in half stops.
As soon as you pick up one of these BD design models, you will notice its true quality features. The sturdy ABS body and the additional rubber armoring provide durability in the optical systems, even when the going gets tough. Further distinguishing features are the intricate lens systems with their multicoated roof prisms which provide excellent contrast and extremely high resolving power, even under critical light conditions.
