– according to APM, this 8×30 will remain prototype and will not be introduced to the market.
However, the design and construction of the binocular being in the hands of KUO China, other optics traders are ordering this model in China and are selling it under their own brand names, such as e.g. Orion with the Orion 8×30 ED model.
