Okay. I will follow your suggestions. Here are my AI setttings per question and answers accompanying the mod download. Usually, I am sunk when I am in position to attack a convoy and at or right below periscope depth. Any deeper and I cannot track the convoy I am attacking. Here you are:
TMO1.7/data/cfg/sim
[Hydrophone]
Detection time=1 ;[s]
Sensitivity=0.15 ;(0..1)
Height factor=0 ;[m]
Waves factor=0.5 ;1.0 ;[>=0]
Speed factor=15 ;[kt]
Noise factor=0.25 ;1.0 ;[>=0]
Thermal Layer Signal Attenuation=3.0 ;[>0], 1 means no signal reduction, 3 equals signal reduction to 33%
