Yes, it was recently discussed that blowing ballast doesn't seem to draw attention in SH3.
Maybe I will give that a try. Thanks.
In other sims if you need to get to PD quickly from being on the surface, you might order a crash dive followed by a PD, but that doesn't seem to work in SH3. You keep going down. So, I was worried that blowing ballasts and trying to level off would result in broaching.
Now, I have already completed my patrol in AOD and am in SHCE. Will be back to SH3/GWX soon. I like playing all three of these games, since each offers differents options and experiences.
