FOR IMMEDIATE RELEASE

August 10, 2005

EdgeTech has added another system to its already successful sub-bottom line.  The new 3100-P Sub-Bottom Profiling System is EdgeTech's portable solution for sub-bottom imaging.  The 3100-P System uses Full Spectrum ("chirp") pulses to create high-definition image slices of the sub-bottom structure.  It can be used in rivers, lakes, ponds and in the ocean. 

The 3100-P System comes with a choice of two (2) tow vehicles to meet the penetration and resolution requirements of a survey.  The SB-216S tow vehicle has a frequency range from 2-16 kHz and the SB-424 tow vehicle from 4-24 kHz.  Both vehicles use specially designed transmitters with low Q-wide band characteristics best suited for "chirp" transmissions.  Two (2) multi-element line array hydrophones are installed in the tow vehicle to reduce acoustic scattering from the sides. 

The 3100-P System comes with the standard EdgeTech 3100-P Portable Topside Processor which consists of a splash resistant topside case containing the amplifier and Full Spectrum electronics.  A laptop computer running EdgeTech's DISCOVER sub-bottom software is where the sonar data is displayed and stored.   

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.
