I'm assuming that Lowrance's recently announced StructureScan 3D is a form of Phase Differencing Bathymetric Sonar (PDBS). PDBS used the phase difference between two or more receiver elements (the Lowrance units has two) to determine the angle of the acoustic return. Thus, it is possible to reconstruct a full cross-track bathymetric profile. While this feature has been available in high-priced commercial side scan sonars, Lowrance's StructureScan 3D would seem to be a first in the 'consumer' market.

While there are other sonar processing packages that process this type of data, they cost thousands of dollars. Any chance of a ReefMaster add on module to enable extracting full side-scan bathymetric profiles from PDBS data (specifically Lawrence's version)?

Here is a good presentation on the state of the art: Further Developments in Phase Differencing Bathymetric Sonars

And more here: Shallow Survey 2015 Conference (see #2)

We are hopeful that we will be able to use the SS3D data in some form. No firm plans yet but we will let you know if and when there are.
