In 2016, Kahles started to sell a new line of binoculars, the Helia series. At first, it consisted of an 8×42 and a 10×42 model, complemented more recently with two range measuring binoculars (“RF”) of the same size. In 2018, an 8×56 model was added to the series. Unlike its earlier binoculars (see separate posts https://binocular.ch/kahles-8×32/  and https://binocular.ch/kahles-8×42/ ), not only is the Helia not produced in Austria anymore (although some steps of the manufacuring process may possibly still occur in Austria), the x42 line of binos also shares all their basic characteristics, except some external details, with same size binoculars from other brands, specifically the Belgian Kite Ibis and the German DDoptics EDX, both produced in Japan. This suggests that the Helia is also essentially produced in Japan, and there is no explicit mention in the catalogue of “made in Austria” which would contradict that (whether this is also true for the x56 model remains to be verified). Like the mentioned two models from Kite and DDoptics, the Helia is a nice upper middle class binocular with good allround performance. Kahles targets primarily the hunting market with it.
