L-3 Klein Associates, Inc. completed a week of important on-water demonstrations at the U.S. Hydro Conference held April 25–28 in Tampa, Fla. L-3 Klein showcased tandem operation of its all-new HydroChart 5000 phase differential bathymetry sonar (PDBS) system and System 3900 search and rescue portable side scan sonar system. This integrated solution was deployed in a wide variety of locations throughout Tampa Bay, providing the sharpest possible views of the seafloor.

L-3’s HydroChart 5000 can be pole- or bow-mounted and features a next-generation PDBS that utilizes advanced interferometric technology to provide IHO special order bathymetry data suitable for charting. The system readily integrates with a motion reference unit, multiple GPS antennas, sound velocity instrumentation and other sensors for highly accurate positioning in water 50 meters deep or less. In addition, with its standard-equipped, top-of-the-line System 3900 true multi-beam side scan sonar, featuring proprietary 900 kHz ultra high-contrast imaging, the HydroChart 5000 simultaneously collects multi-beam and bathymetry data in real time for unsurpassed seafloor imaging.
