How to see bottom contour

[Anonymous]

I just received a TZ touch 2 and I am having trouble getting the unit to display the bottom contour. Do I need to install a Jeppsen fishing chart for this purpose? Is there a chart type I am not displaying properly?

Thank you

Besides spot soundings and other info on the navigation charts, the 3D bathy data can used. Try using the Depth shading feature it is a great tool for seeing the depth levels/contours. If you are in the USA and fishing 100ft and deeper to the continental shelf, you can try the fishing charts that are preloaded in the unit by choosing FISHING as your chart type. As another option you want high res bathy data for the USA, C-map now has a bathy offering for $100 list.
