Cleared tracks can I still export depth information?

I recorded several hours of depths on my new Helix 9 but got tired of seeing the red track line so I cleared it before saving it. The depth information still displays and there is no red line. I would like to export this depth information but cannot find a method to do this. I assume that the depth information only gets exported with the tracks? Can someone help me understand how the unit then still provides the depth contour information without the tracks. Each depth reading must be associated with a GPS coordinate. Is this exportable?
