What is going on here?

Does anybody understand why my display is blank for large sections of my local waters? Contour lines just disappear.

Nice start line.......no survey data or that map sector isn’t included in your map set

It looks like that data is not included on your map. It will continue on a different map.
You might have to get the other chart to see the rest.
Go to Lowrance website and see the coverage of your chart.

I have seen other manufacturers include up to a certain point, then cut if off like that. if you want the rest of the data, you need to buy the rest the chart

In some situations the chart display information changes with the scale used in the presentation ("zoom").


ASIDE: Usually a Lowrance chart plotter provides for making and exporting screen capture image files. Using a screen capture image file is a much better way to illustrate the screen appearance than a photograph.
