Thanks Benny. That is a good tip. I take him out and he stops. What was funny is in a new mission I had him track while submerged, then I surfaced and had my watch give bearing and range. Course my Hydrophone guy was giving updates too. Hilarious. So I took him off his post. I was parraleling the ship for awhile. So I thought after maybe 15 minutes I'd put my Hydrophone guy back at his post while still surfaced and he started giving updates again.
I mean this guy is dedicated I think. So now I only put him in his post just before I submerge.
