ABSTRACT:
Apparatus for detecting and measuring forces on a fishing rod due to pull on a fishing line associated with the rod or to a weight hanging on the rod, includes a transducer responsive to the deflection of the fishing rod to provide an output indicative of the amount of deflection of the fishing rod, and a timing circuit including a signal counter which counts signals during a time interval and provides a numerical display corresponding to the number of signals counted and thus the force being applied to the rod, the timing circuit being controlled by the transducer to vary the duration of the time interval during which signals are counted whereby the number of signals counted by the signal counter varies in correspondence with the amount of force being applied to the rod. In one embodiment, the transducer includes a wire having its ends attached to the under surface of the rod inside chamber and a potentiometer connected in the timing circuit and having its wiper mechanism connected to the wire and movable thereby when the rod deflects, whereby the resistance of the potentiometer varies with rod deflection, varying the duration of the time interval during which the signal counter is enabled to count signals.
