Description

The EdgeTech 3100-P Portable Sub-Bottom Profiling System is a low cost portable sub-bottom profiler system. It uses Full Spectrum (“chirp”) pulses to create high definition image slices of sub-bottom structure below the bottom. It can be used in rivers, lakes, ponds, and in the ocean.

The EdgeTech SB-424 towfish has a frequency range from 4 - 24 kHz. This towfish uses special designed transmitters with low Q- wide band characteristics best suited for “chirp” transmissions. Two multi element line array hydro-phones are installed in the tow vehicle to reduce acoustic scattering from the sides. This results in a narrower across/along track beam pattern. A linear power amplifier is used to generate clean, harmonic free transmissions. The portable 3100-P topside case contains the amplifier and other Full Spectrum electronics. A laptop computer running EdgeTech's DISCOVER software is where the sonar data is displayed and stored. A number of industry standard thermal gray shade printers are supported.
