Abstract : The present invention is directed to providing a circuit for inducing electronarcosis in a marine predator and includes a source of DC power connected to a switching inverter. An astable multivibrator, having a predetermined switching rate, sequentially completes the switching inverter circuit, via a switching transistor, serially-connected in the inverter's feedback loops, to provide a partial duty-cycle conserving battery power and prolonging the effective life of the shark dart.
