Ok - made a test mission
I am 30m deep
target is 60km away heading to pass me side on at 8knots
Run the mission
The target is first spotted at 33km and hydro line is drawn on map
no call out or message
target heads towards my at 8knots
hydro line shows where he is the whole way
not shout out from hydro at any time.
Then the targer disappears as it passes by deaf spot off the bow.
When the target reappears the sound man calls out and message is posted
new updates are shouted out and posted as the target moves away out of range
Second go - ran same mission again
target spotted at 32km
this time i ask hydro to repeat last contact
contact is posted, but no shout out
sound man remains quiet and no more messages posted
the hydro line tracks target
again target passes my bow and is about to go into my deaf zone
still no message posted or call outs
as target re-enters by the hydro zone
sonar man posts message and calls out
he continues to call out and post messages until out of range
So - my issue is this
when using real nav - the hydro line is not marked on your map
this line is the only warning you will get unless you ask
or unless contact is lost and then found again before he will start reporting
