So today i'm running my first list, and i just added No_contact_shapes_or_colors_dashed_contact_line_1_ 1_0 wich is very fine for me at the moment.
Though... using rotative hydrophone, why i can't ask my hydro guy a rough distance or precise distance to contact when i'm looking at it with periscope?

When periscope is fully lowered this feature is avalaible, but as soon as i follow the target with periscope (and she is enough close to lock it BTW) the distance to contact is greyed...
Any idea?
