Sub-bottom Profilers are a special kind of singlebeam echosounders, that operate with very low frequencies, that allow to penetrate and scan the upper layers of the subseafloor. There are linear and nonlinear sub-bottom profilers, whereas the work principle of the latter is based on the parametric effect.
ECHOES 5000 is an energy efficient and compact sub-bottom profiler (SBP) system allowing high resolution surveys in various operating conditions (lake, shallow & dee
