A warm white light works best for muddy water and a cool white light works best for clear water. The Swamp Eye Lights offer the best color light for flounder gigging because they are adjustable from warm white to cool white for different water conditions.

Typically gigging for flounder is done at night using a light to illuminate the bottom and spot the flounder, which are known to hide in the sand or mud. Once a flounder is spotted, the fisherman will use the gig to spear or stab the fish, either by hand or with a pole.
