The ultimate jig under the complete supervision of Norihiro Sato.The concept of this jig, was initially for long fall, but as we proceeded with the test, performance other than fall performance was also good, so we developed a pilot jig from long fall.The assist hooks and split rings used in all tests are from ASS. It was completed as a pilot jig with results in all tests in shallow water areas, fast tide areas, and deep water areas.
