System and method for coupling an overpressure wave to a target media

A seismic exploration system, comprising:

• an overpressure wave generator for generating an overpressure wave;
• and
• a coupling component for converting a pressure of said overpressure wave into a force that produces a conducted acoustic wave in a target media, said coupling component comprising:
• a coupling chamber for receiving said overpressure wave from said overpressure wave generator;
• a push plate assembly, comprising:
• a top plate;
• a piston rod;
• and
• an earth plate;
• a movement constraining vessel for constraining movement of said push plate assembly resulting from said coupling chamber receiving said overpressure wave, said movement constraining vessel comprising;
• a stabilizing component for constraining movement of said piston rod to only movement that is substantially parallel to the sides of the coupling chamber and the movement constraining vessel;
• and
• a sealing component for substantially sealing said coupling component during generation of said overpressure wave;
• and
• a stop component for preventing said movement constraining vessel from striking said earth plate.
