Quickly create your own PBG (Personal Bathymetric Generator) Shaded Relief Maps using SFD and the DFF-3D or Fish Finders. Bottom images are drawn with shaded relief, depth contours, and variable colors, making it easy to identify hidden structure and ridges that hold fish in a simple,easy-to-interpret presentation.

* The above diagram shows almost the same area mapped with each beam. The red line is your ship's wake. A single beam only provides information
directly below your ship, whereas a multibeam detects a 120° width to the left and right, making multibeam more efficient at creating seabed maps.
When using the seabed mapping function with a single beam, it is not possible to display fish finder echoes.
* Recommend connecting a satellite compass as it reduces the effects of wave swaying.
* Chart overlay is not possible.
