I am shopping for a new, sonar/gps combo. I am currently interested in the Lowrance HDS units. I will primarily be fishing the San Juan Islands and would like the option to add radar in the future. Has anyone tried the insight mapping options that allow you to build your own charts? This option is what drew me to Lowrance in the first place. Is structure scan worth it? Are there any other brands/models that I should be considering? I have saved around $2K for this upgrade. Any advice is much appreciated.
