Flashers are a great tool to have with you when you are hunting pelagic fish, but they also work great on reef species.
Tuck them in your belt until you need them. These flashers sink at a slow rate and if you prefer a faster sink rate, justattach a little weight and they will sink faster. When you see a fish on the edge of your gun's range, simply throw the flasher out of the water toward the fish. When the flasher hits the water, fish generally come closer to investigate.
