The "Tuna Ring" has quickly become popular with the popular Kihada Tuna in Sagami Bay (our product is "Super Tuna Catcher").
By sending a ring that is the right size to create a thread, stealing the freedom around the gill lid, it is a simple and highly effective tool that prevents breathing and weakens tuna at once, but there are weaks in actual use.
Most rings have chipping points on rings so you can quickly set them on your strand, depending on the situation, the ring will fall off from the chipping part and get immersed in the sea.
This product is a "tuna ring safety device" developed to follow the weaknesses of tuna ring.
For use
Put your tuna ring through the O-ring at the end of the end and hook on the other end to set it.
For fukasetics, please use a No. 1 or more power swivels between the Harris and the leader.
