Silver reflects hard and reads as a scaled baitfish — glass minnows, sardines, small threadfins — which is what shallow reef fish are hunting.
Forty-five grams is light-tackle jigging weight for nearshore reef, shallow wrecks and slack tide. A lighter jig hangs longer in the strike zone, which is the biggest trigger for a fish holding rather than chasing.
Best in clear water with good light. Assist hooks top and bottom.
