The stiff rod in combination with the braided line provides a spectacular action with the popper moving towards you and creating big splashes intermittently. This action cannot be achieved using nylon line that has too much stretch or with long rods, which are too flexible in most cases. We used very effective but more tiring sinking poppers. Cast the sinking popper towards the reef and start reeling in at maximum speed just before it hits the surface. Based on the enthusiasm raised with hitting fish, a very effective technique too.
Fishermen usually spend lots of time searching the fish.
Especially with sinking poppers reeled in at high speeds, a Giant does not have much time to notice a popper, swim to it and attack it when you have only cast 30m. Stay far away from the reefs, at least 100m. It can take many casts to wake a giant. Fishing for Giants closer to the reef is useless as the fish cut the line on the coral within seconds. Casting before and after lunch with two or three people quite often raised fish, even on the inner side of the reefs, which normally are less productive.
