For those in the market for a compact binocular, the B2FF is a great option. Employing Fixed-Focus optics technology, there is no need to mechanically focus the device to bring objects at different distances into focus; just power-up and view. A fixed-focus binocular is designed for applications where rapid target recognition and identification are important. Fixed-focus optics allows you to size-up targets quickly, regardless of where they are located in your field of view. Objects at varying distances away, in the same scene, will all be in focus. A proprietary interocular hinge guarantees that both optical channels are always centered precisely over each eye.
