This rig is primarily designed for mantis shrimp and uses three small hooks arranged in a tiered configuration. The rig has a two-tiered structure, with the upper and lower hooks being free-sliding. According to one theory, mantis shrimp have a habit of taking their prey back to their burrows. This rig aims to increase the hook-up rate by allowing the mantis shrimp to move freely. When fishing for mantis shrimp, the goal is to hook them somewhere on their body rather than in their mouth. Using three small hooks increases the chances of this. Small pieces of live ragworm are considered effective bait. Bites are often not very clear, so it's a good idea to lift the rod and check after a certain amount of time has passed. You can bait all three hooks, but it's also effective to bait only the top and middle hooks, leaving the bottom hook free. While targeting mantis shrimp, you may also catch gobies, which inhabit the same areas. Also, by changing the hooks to larger ones, you can target various other fish species. As anglers are aware, please be sure to check the fishing rights situation at the fishing spot beforehand. Please be careful, as catching certain fish species, such as mantis shrimp and octopus, may be prohibited in areas where fishing rights are established. Thank you for your consideration.
