One primary requirement drove the SQ17-00 design project: the need for a compact seismic hydrophone. In the end the hydrophone turned out to be about half the length of our SQ05-06. The SQ17-00 is ideal for systems in which space is limited. It is a remarkably compact seismic hydrophone yet it still offers good sensitivity and has a high depth rating.
