Thanks for the input!

I have Werner Sobe's tutorials from way back when they were released and any time I return to SH4 i watch them again and again.

I also downloaded the tutorials that CapnScurvy mentions.

Now i am at my first patrol with full realism settings in the game options and while an route to southern Formosa i was making a hydrophone sweep and picked up some contacts. By the way sometimes the game lags when a convoy is close

so you know you found something

. I think i read about this some time long ago.

How to proceed now that i have those contacts on hydrophone?
I will list my activated mods in the hopes that if i put them wrong it could be corrected:
1. TMO 2.5
2. TMO small patch
3. Convoy routes TMO+RFB
4. TMO Sub textures FooSkin
5. RSRD
6. RSRD Patch1
7. OTC
8. OTC Realistic scopes
9. OTC Tokko's revenge
10.ISE v3 TMO&RFB
11. ISE Realistic colors
One more thing, has anyone tried to make a mod that simulates what Toprx was saying about real life situations?
