Just received my 2 new Lowrance 12" HDS Touch Gen3 units with the New 3D Structure Scan. You must have the Gen3 units to work it.

Amazing new underwater view. You can really see what you looking at now without the guess work.

Check out the video. It explains the increased side image range even in shallow water.
