Currently the TZT3 depth shading feature is its own layer. what this means is the specific depth shading layer may not follow the contours as the chart being displayed, such as when using a different chart such as c-map fishing or otherwise.
My suggestion is to re-design the depth shading layer such that it is not it's own map, but simply a re-writing of code to show depth shading on the specific chart being displayed. that is, a dynamic creation of the depth shading based upon the bathymetric contours of the exact chart on display.
This way there won't be conflicts of depth shading and chart bathymetric lines which is the case many times when using the c-map charts or fishing charts, or even updated noaa charts I have noticed in areas where the charting changes often due to shoaling and what not.
