Abstract : The patent pertains to a self-contained acoustic beacon activated by a seawater switch for providing an independent method of locating and recovering a floating or submerged recoverable target. The device provides an ideal operating life for target recovery of about 36 hours as well as providing an extensive underwater range. The device also provides stable frequency operation without a crystal-controlled oscillator over a wide range of source voltages allowing use of inexpensive batteries as a voltage supply source. Additionally, the signature or output signal code of the device can be changed simply and quickly providing positive identification of the acoustic beacon and lengthened operating life span.
