Wait.. you can DIVE under the sea? But how will you sink the targets? The deck gun doesn't seem to work underwater. Please help!

But enough fun.

Without Map Contacts you can't see the Hydro Lines. Which is just stupid... I wish there were a separate option for those. Anyway...
1. Use Map Contacts, that way the blind-deaf crew will no longer be an issue.
2. If you did make the mistake of upgrading the hydrophone you won't be able to use it on the surface. So yeah... it's better to dive from time to time, but mind the battery drain at high TC.
3. Plot a circle with the compass tool, centered on the patrol area point. Make it 200km in radius. Then try to stay inside that area. Any ship you sink outside it will not count for completing the patrol. Since finding a ship is a crapshoot, you can choose to stay in one place submerged for most of the day, or wander around like crazy burning fuel. Your choice.. I usually place myself along strategic lines, near shore or near harbors. The narrow Straits can be a gold mine too.
