I'm building a map in AT5 format. My settings are shown in the attached Clipboard01.jpg. I do not see any way to select different depth ranges for highlighting when I view my map on my Lowrance...all I get is one check box for (AREA) Depth Highlight and one for (AREA) Depth Area on my chart categories. Depth area appears to be my colored isobaths. If I turn this off but have depth highlight on, I get red highlighting on all isobaths...so I'm assuming this is where I should be able to select depths to highlight, but don't see any option. I'm using both a Carbon and a gen 2 touch model...both behave the same. Can anyone tell me what I'm doing wrong here. In case it matters, I have the following layers in my map (in this order from top to bottom of the layers list): minor contours, isobaths, major contours, shorelines, hardnessPSV, and two small side-scan mosaics
