As you chum play out live mackerel on your lines about 30 yards apart. Be patient the wait can be hours long. Meantime the ever present blue sharks will probably jump on your hooks and keep you busy snipping and re-twisting wire leaders. Blues are not very edible but put up a credible fight. Mako's are twice the fighters and more.
Blues are really secondary targets for the anglers.
Many fishermen are finding Mako's at 300 feet sometimes more. Apparently this method works best in the middle of the day because it's said the sharks avoid direct sunlight. You fish with the same tackle but attach it to the Down-rigger ball and lower it to a pre determined depth. From here you either drift or slow-troll. Whether you slow troll or fast troll always speed up the boat to full RPM's when you get a strike.
