Used by professional fishermen for many years, the circle hook is almost "self hooking". There is no need to strike and set the hook into the fish. Being round in shape, the hook will roll into the corner of the mouth of the fish for strong hook up.
The best baits are pilchards, sardines, squid, cuttlefish or any oily fish fillets / pieces. It is very important to use plenty of berley and fish oil to attract Snapper to your area.
