Benefiting from 30 years of field experience, Echoes Series of sub-bottom profilers are perfectly suited for deployment on both autonomous & manned maritime platforms. Developed in close collaboration with the French Navy and several International Oceanographic Research Institute laboratories, including the French Research Institute IFREMER, Exail sub-bottom profilers benefit extensive practicing and cumulative return on experience coupled with constant innovation and evolution.
Seismic profiles from Laacher See volcanic crater lake (Eifel, Germany).
“I have been using Exail Echoes sub-bottom profilers since 2001. Their efficiency in terms of resolution and definition enables us to get the geometry, morphology and size of sedimentary components we try to reach and characterize.“

Gas detection and quantification using iXblue Echoes high-resolution sub-bottom profiler and Seapix 3D multibeam echosounder from the Laacher See
IEEE 2021
We present preliminary results from near-surface geophysics of sedimentary deposits and water column gas distributions and quantification from an Eifel crater lake (Germany), using iXblue Echoes high-resolution sub-bottom profiler and Seapix 3D multibeam echosounder.
