My Navionics chartplotter on my tablet enables me to change the depths where the white, light blue and dark blue depth shadings appear. I have all depths more than 2m ( my Bavaria 38 needs 1.9m) at datum showing in white to enable clarity.
The axiom pro does not appear to do this. Am I missing something?
I think it should work like this:
Select the chart window.
Go on "Set up" ("Einstellungen" in German).
Select the desired deep for "shape of deep water"
Select the desired colour for deep water.
Thats it.
