S!
I'm playing a Black Sea campaign at the moment, and it seems that Uncle Joe's boys don't really have it together when it comes to active sonar. They usually lose me once I'm at 120m or so, but I'm just wondering whether their systems really were that primitive...
Does anyone have any real historical information about the system(s) they used, such as their cutoff depth / range and the downward angle etcetera? I've googled for clues but have hit absolutely nothing so far!
Thanks for any infos you can send my way ladies and gents
