Abstract: Two equal sized sheaves, each having a crank handle, are journaled for independent rotation. A sinker weight is supported on the loop of a control cable whose ends are attached to the respective sheaves. The control cable extends tangentially from the bottom of one sheave and the top of the other. Rotating the sheaves in the same direction transfers control line from one sheave to another without raising the sinker. Rotating the sheaves in opposite directions simultaneously or in sequence raises and lowers the sinker depending on the selected directions of rotation. A fishing tackle line which is attachable to the control cable may thereby be raised and lowered independently of the sinker weight.
