Much better detection for escorts, those are NYGM values, even visual distances...quite fun

For first time in my current career (1941) was unable to attack the convoy even with 7m/s sea, was repulsed and depth charged for hours ... but survived.
I like the way my crew spot ships when i see only smoke on horizon now! Before i could see the whole ships before my crew called me.
Seems NYGM values are working quite good with Ccom so far.
