The SQ05-06 is a high pressure seismic hydrophone designed specifically for use in seabed acquisition systems. It uses a piezoelectric ceramic sensor designed specifically to perform in deep ocean environments. It is rated to a depth of 3500 m (11,500 ft). For accuracy in deployments of different depths its performance has been well characterized under changes of both temperature and pressure.
