plummet


plummet
1) a cone-shaped lead weight with a loop at the top and a cork base. A hook at the end of a fishing rig is threaded through the loop and embedded in the cork. The rig is cast out and the plummet takes it to the bottom. The position of the float can be adjusted so that just its tip is visible above the water surface. The plummet is then removed and the rig fishes on the bottom
2) a metal weight with barbed points used to pierce flatfish lying on the sea bed
