This is a gang rig for fish like the thread-sail filefish (Kawahagi). Place bait such as krill or cut bait in the cage. When the fish nibble, you'll feel a bite, so quickly jerk the rod upwards to hook them. You can catch not only thread-sail filefish, but also horse mackerel, mackerel, sea bream, and other fish. It's designed to fold compactly for easy transport. Please refer to the images for the size. We have great fishing items available. Thank you. #FishingTackleForSale
