This is for anyone who has the issue where their depth contours do not dissapear when using the 'no contours' option to display shaded relief (or your own raser charts).
Here is something helpful for 0.7.4.0 since custom categories were added in previous versions (quite a while ago), but no one may have noticed this yet.
On
HDS units there is a 'shaded relief' option and a shaded relief 'no contours' option. If you want your contours to disappear when using the shaded relief 'no contours' option, you will need to make sure the MIN_CAT = Depth Contours. Any other value will prevent the contours from being hidden on the unit software. This should currently affect any HDS model. Have fun
