“Initially, our fish finder was sold for 600,000 yen per unit, which was as expensive as a house in those days. Despite its high price, the company’s technology attracted fishermen from all over the country. In fact, I heard that a number of customers in the fishing industry visited FURUNO (which was formerly based in Nagasaki City) with backpacks full of cash to buy our fish finder,”

  The Furuno Fish Finder is said to be the world's first practical fishfinder; it was introduced by the Furuno brothers for use in commercial fishing vessels in *1948* in Japan.
