If you are picking up the sound contact by listening yourself, no contact line will show on the map until your stone-deaf sonar man can hear it too. So you need to get closer.

Point the bow of your boat directly at the contact, then monitor the sonar yourself to determine if the contact drifts left or right of zero degrees.

That will indicate his general direction of travel relative to you. If he doesn't drift either way, then he's either heading straight towards or away from you.

Now that you have some idea of his course; surface, point the bow of your boat 10 degrees ahead of his last bearing and travel in a straight line at flank speed for 10 miles (use your maptools to measure this).

Once there, submerge and find him again on sonar. Repeat until you get a visual contact (that's usually within 2-3 hops).

Happy hunting
