We've enhanced our standard basemap to deliver more detail and a superior angling experience. Built into GPS-equipped HELIX™ Series G2 and G2N models and based on current data from LakeMaster®, NOAA and other trusted sources, these accurate maps provide you with a clear view of underwater terrain and surrounding points of interest so you can fish and navigate with total confidence. A new standard has been set.
