FOR IMMEDIATE RELEASE

March 20, 2006

EdgeTech will be introducing a new dual simultaneous 300/600 kHz option for their existing 4200-FS Dual Mode Side Scan System at this year’s Oceanology International show. The current 4200-FS System operates dual simultaneous 120/410 kHz frequencies and has enjoyed great success since its introduction in late 2004 with 65 systems currently in operation.  The 4200-FS Side Scan System will now be available with either 120/410 kHz or 300/600 kHz dual frequencies. 

The new high frequency option will provide the user with superior imagery at ranges of at least 230 meters per side on the low (300 kHz) frequency and 100 meters per side on the high (600 kHz) frequency. This system is ideal for applications where high resolution imagery is required, such as Mine Countermeasures (MCM) and artifact tracking. 

The High Frequency 4200-FS System will still provide the user with two software selectable modes of operation for added versatility. In High Definition Mode (HDM) the system operates conventional dual simultaneous 300/600 kHz frequencies. In High Speed Mode (HSM) the system operates in Multipulse mode on either selected frequency at speeds of up to 10 knots while meeting the IHO and NOAA specifications for side scan surveys. Real time selection of these two modes allows the user to choose the one best suited to his task at hand. 

Fugro Survey UK has recently placed an order for two of the EdgeTech High Frequency 4200-FS Systems to be fitted onto their new Focus-2 ROTV systems. These systems will be used for acoustic pipeline inspection in the North Sea. For more information visit Fugro’s website at www.fugrosurvey.co.uk.

The new 4200-FS High Frequency Side Scan System can be seen at stand number 427 at OI 2006. For more information on the system please send an email to marine@edgetech.com.

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