Helix 9 G3 Mega SI - contour depth increments - how to set?

[Netbender]

Good Day, does anyone know how to set the depth increments to something other then 10' in the chart mode? I have a LakeMaster Plus V2 crad installed. Just trying to see something more accurate then 10' 20' 30' etc. 

 

Thanks!!

Thanks wishinfishin, I checked this out but nothing around contour mappings. Anyone else know of how to get more accurate depth contour readings from lakemaster plus ver 2?
