HDS Carbon Software Upgrade (v 4.0)


Find more fish, easier and faster. See bottom structure in even greater detail and get simpler navigation when you upgrade compatible Lowrance® displays with the new software release.

 At the heart of the release is FishReveal™ smart target viewing, an exciting new sonar feature for Elite Ti, HDS Carbon and Gen3.  Plus, HDS Carbon gets massive enhancements to any high-frequency imaging (scanning sonar) transducer plugged into it like StructureScan® HD/3D.  Elite Ti, HDS Carbon and Gen3 get a sizable bump in automatic navigation and map readability through the addition of  C-MAP® Easy Routing and Navionics® Dock-to-Dock Autorouting capability and the new C-MAP® navigation palette.
