I have completely mastered the use of the attack disk. It's just a PITA when you ask a sonar guy the bearing to update position on the true course line and he says "no sound contact"
But the sound of a contact can be heard very well on hydrophone. Incompetent fool!
When this happens I do have to takeover a seat of sonar's guy to check the bearing myself. But it's quite annoying everytime this happens.
