I’m looking at the HDs live 7 and specifically at the structure scan custom mapping. Basically you ride your boat over a location and it makes a map of all the structure in 3D. It looks like an entire map but in down imaging. What transducer do I need to use the structure scan view? Is there a cheaper unit that will do structure scan. I don’t care what brand. Thanks for your help too

C-MAP Genesis Live mapping, which allows anglers to create up to 1/2 foot contour maps, in real time, on the HDS LIVE 7 display.
