Yeah we have them here in tackle stores in New Zealand. Here they are called Daiwa Pirate Jigs and are used in the same way as Shimano's lucanis slow jigs. Pretty popular and work well on a wide variety of fish.
Sorry for the late thanks. Soooooo then you work them slow on a very parabolic rod and let the fish climb on it??????? I was hoping it was more like power jigging (not to be confused with electric reels.) Wife says I need to burn more calories.
Nice fish Joey H
One of these days I hope on getting to New Zealand. Do some King fish and visit AMF boats.
