For Mahi, I recommend 5/8-1oz top-water baits for the most exciting game fishing, to catch even spooked Mahi. Large 2oz baits are great to catch big one among a lot of school of Mahi.

Top-water baits with vivid-fast dog-walk action with splash are most effective and exciting. Please imitate their favorite prey, flying fish, is just escaping from Mahi. Please make dog-walk slowly at first, then fasten it gradually after you see Mahi chasing after it. And, it is very important, you make a super-fast vivid dog-walking action and sub-second pause at 15m/yards from boat, and bang! Mahi may not resist to bite the bait.

Poppers are effective when Mahi are very attacking. They are fast to catch only high-charged Mahi. Popping with long stroke and large splash is very effective.

Jerking baits are effective when Mahi are not much chasing top-water baits because water temperature is not high enough, or they are spooked.

For hooks, please use high quality saltwater hooks like, ST-46 from Cultiva hooks, or equivalent. At last, you'll need a very high quality polarized glasses to find mahi, and I recommend Talex lens made in Japan. Zeal optics offers high-end quality glasses.
