This patent describes an apparatus for imparting a seismic signal into the earth. It comprises seismic generator means for generating a seismic signal, comprising: an impact mass; and propulsion means for driving the impact mass to produce the seismic signal; coupling means, in engagement with the earth and engagable with the generator means, for transferring, into the earth, signals generated by the propulsion means driving the impact mass into engagement with the coupling means; lift frame means located above the coupling means and resiliently connected thereto; hollow housing means encompassing at least a portion of the generator means for inhibiting the entrance of water into the apparatus when used in an underwater environment and for confining noise produced by the apparatus when used in an atmospheric environment, comprising: a first end portion connected to the generator means; and a second generally annular end portion, the second end portion extending toward the coupling means; an annular connector member flexibly connecting the second end of the housing means to the lift frame means; and pivot means pivotally connecting the seismic generator means to the lift frame means.
