VIVI Falcon 12x56ED binoculars are the most powerful long-range instrument in the Falcon series, pairing 12x magnification with the premium 56mm platform and the line-up’s highest twilight factor of 25.9. Built to resolve detail at extreme distances — and to keep resolving it as the light falls — they combine ED extra-low dispersion glass, FMC multi-layer coating and a phase-coated BAK4 roof prism into a genuine long-range observation tool.
