The Demountable Jig system has been designed for speed and versatility. You can swap lures and weights fast without retying, which is crucial in some fishing conditions. This is the original Chebu Rig - this thing started the whole Demountable Jig system, so it is an all-time classic.
Heavy-duty wire connector with extreme stress test - you can comfortably lock your drag and not worry about losing fish because of the connector
Colored jigs are perfect for playing with some combinations (try red head and white body)
