The Meopta Meostar B1 is a 8 x 42mm Waterproof & Fogproof Wide Angle Roof Prism Binocular. When you prefer a big, bright view that's as uncramped as it gets and don't mind the extra mass and weight which must come along with these demands, you'll want a binocular such as the Meopta Meostar B1 8 x 42mm.
The 8 x 42 Meostar B1 is part of the Meopta flagship, the Meostar series. The 8 x 42 configuration is likely considered the best all-purpose birder's tool and the Meostar is among the extremely short list of 8 x 42 units which have an apparent viewing angle (actual angle of view multiplied by magnification) of greater than 60°. You will notice the difference between other 8 x 42 units that are not 'wide angle' binoculars immediately.
