After the basic development was completed, Tracy set up a half-year test fishing period and conducted a thorough field test with six field testers nationwide, led by professional angler Masanori Muraoka.
Tests were conducted in all fields from shores, surfs, rivers to harbors and boats, and the fish species were not limited to sea bass. I was able to catch it. The reasons have been analyzed in various ways, but many of them seem to be due to their special actions and “ease of use”.
