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.
