I'm not much of a tarpon fisherman so take it for what its worth. While tarpon will come in casting range of the shore, (mostly early) you may have better luck, especially if there are swimmers, kayaking a bait out or fishing from the yak. Live pins or threadfins, fished anyway you please. Ladyfish, mullet and mackerel all make fine live, whole or cut baits too. Other fish will also be accepted by tarpon, like small jacks, whiting or silver trout for example. If they are hungry, they will almost always take a easy meal. You may get some shark action too, but if you stick with mono leader, most will cut you off and you can get back to tarpon fishing. If you see bait pods, match the hatch. If they are eating glass minnows, they may only eat those when they are being picky. I have caught them fishing for mackerel on small pilchards right at the idle buoys too. Good luck.
