StructureMap™ HDS Gen 2 Addendum StructureMap is a tool that allows you to overlay SideScan sonar returns on top of the chart, giving you a birds-eye view of underwater structure below and beside your boat. StructureMap makes it easier for you to visualize the underwater environment in relation to your position and aids the user in interpreting sidescan sonar images. Refer to your HDS manual for basic information about HDS unit operation. Refer to your StructureScan manual for more information about StructureScan.
