FOR IMMEDIATE RELEASE

March 10, 2004

EdgeTech has just completed work on the latest addition to their line of products. The new 4200-FS Dual Mode Side Scan Sonar System provides a unique advantage over conventional dual frequency side scan systems by combining EdgeTech’s Full Spectrum and MultiPulse technologies into one unit.

The 4200-FS Side Scan System offers two software selectable modes of operation:

• High Definition Mode (HDM) – conventional mode operation with extra long array (90 cm) for superior resolution; excellent for Mine Countermeasures (MCM's).
• High Speed Mode (HSM) – dual pulse operation for speeds up to 10 knots, while meeting NOAA and IHO requirements for “hits on target” compared to conventional systems at 4 knots. This is an additional feature for high-speed navy patrol vessels.

While in HDM the 4200-FS system operates simultaneous dual frequencies (120/410 kHz) and when in HSM the system will operate in MultiPulse mode on either selected frequency. Real time selection of these two modes allows the user to choose the one best suited to his task at hand.

The new 4200-FS system can be seen at stand number 427 at Oceanology International 2004 London and on the EdgeTech website at www.edgetech.com.

Uses for side scan sonar include geo-hazard surveys, geological/geophysical surveys, route surveys, archeological surveys, and search and recovery.

EdgeTech manufactures a variety of marine products including sub-bottom systems, combined side scan/sub-bottom systems, and modular imaging systems for deep towed, AUV, ROV and other applications utilizing Full Spectrum, MultiPing or synthetic aperture acquisition and processing techniques.
