3400
The 3400 is a wideband Frequency Modulated (FM) sub-bottom profiler utilizing EdgeTech’s proprietary Full Spectrum CHIRP technology. The system generates high-resolution images of the sub-bottom stratigraphy in oceans, lakes, and rivers and provides excellent penetration in various bottom types.
Description
Building on the long running success of the EdgeTech sub-bottom profiler
product line, the EdgeTech 3400 provides users many enhancements to current
sub-bottom profiler systems. The 3400 is a wideband Frequency Modulated (FM)
sub-bottom profiler utilizing EdgeTech’s proprietary Full Spectrum CHIRP technology.
The system generates high resolution images of the sub-bottom stratigraphy in
oceans, lakes, and rivers and provides excellent penetration in various bottom types.
The EdgeTech 3400 comes in a dual 2-16 kHz transducer configuration. The towfish
is configured with new PVDF receiver arrays segmented for standard sub-bottom
profiling operations or a unique “pipeliner” mode for optimal location and imaging of
buried pipelines.
