OM Auto targeting problem

[NebulaPC]

So periscope depth is always too deep, even in calm seas. Even after bringing the boat up to 11m no ships can be targeted until they are 2000m or closer, making attacking large convoys a lot harder than it has to be. And the damn hydrophone doesnt work at anything above PD even though its still underwater.

No, I don't want to do math thanks. Is this mod still being worked on or should I just stick with the pacific mods that seem to actually work? I would just go back to SH3 but I cant justify paying 10 bucks for a decade old game...
