Tuna are predisposed to catch and eat flying fish. These baits are exciting to fish because they work. They are designed to be lifelike and durable. It can be used as a trolling lure on it's own, as a teaser, pitchbait, or as a topwater casting lure depending on the rigging.
Rigging - These lures are easy to rig. Run your leader through the nose, and out the belly. Place a small egg sinker and bead in front of your hook, and crimp it. You can either loop the other end, or run it with a swivel. These also work well when run as a daisy chain.
