SUB-BOTTOM PROFILER EDGETECH 3200

  • The EdgeTech 3200 Sub-bottom Profiling System is a wideband Frequency 

Modulated (FM) sub-bottom profiler utilizing EdgeTech’s proprietary Full 
Spectrum CHIRP technology. The 3200 generates high resolution images of the 
sub-bottom stratigraphy in oceans, lakes, and rivers and provides penetration  
of up to 200m. 

  • The 3200 comes available with a choice of three stable, low drag towfish that 

operate at different frequencies and can be used at depths of up to 300m. The 
selection of towfish depends on the sub-bottom characteristics as well as the 
resolution and penetration requirements.

  • Along with a towfish, a standard 3200 system comes with a topside processor 

running EdgeTech’s DISCOVER sub-bottom acquisition & processing software 
as well as a customer-specified length of tow cable. 3200 can also be interfaced 
to 3rd party software.
