Duc, you off your meds again..
I swore when I played stock I could watch charges just go poof when at a certain depth, but it would've been much shallower than 300 meters.
I never see them go poof anymore, just blow up around me. Not sure what gives, been a long time, but I never see them poof anymore.
They do seem to have a predetermined depth, whatever you sub is at.
I always wondered when and how charges blow. Is there a time the enemy of AI reads sub is at certain depth and that's the depth they blow.
When a escort makes a run and charges hit the water, I assume somehow they're set to blow in footage ranges near your sub, some blow under, some above, but within a range. I often try to switch depths to fool them, but the only way I can do it fast enough is to blow tanks. If I do that, they almost always blow way under. Course I thought blowing tanks would surface you, but you can easily stop it and head back down. I usually only do this fighting Type ABS in 400 ft of water or less, works great, but seems unrealistic blowing tanks doesn't send you to the surface.
