Thank you both so much for the speedy reply. I'm amazed to see how far the community has progressed these last years, some very cool mods and even new games (Wolfpack, UBOAT).
I take your point about the futility of trying to shoot it out on the surface. Once I get a rivet counting detail stuck in my head I just feel the need to ask. I was just wondering if this is a technical limitation of SH 4 or something or other. Thank you again for indulging my pedantry!
Now that I've fussed, any tips to the Type IX? I don't think any of the newer subsims have it, so I'm trying to fall back on memories of GWX and coming up empty. A bit slower to dive, right?
