User’s Manual INNOMAR Parametric Sub-Bottom Profilers / SESWIN 199
Innomar Technologie GmbH (2023-01) 199
A.13 Innomar quattro / sixpack Multi-Transducer SBPs
The INNOMAR quattro and sixpack models are parametric narrow-beam sub-bottom profiler (SBP)
with four/six transducers and echo sounder functionality. The main application is to acquire sub-
bottom data at high resolution in extremely shallow waters at high sounding density and to
produce three-dimensional visualization of these data sets. In deeper waters the transducers can
be combined to provide better range and/or penetration capability.
