Trouble is, all that technology doesn't change the fact that it's pretty
damn dark 500 feet down. There basically isn't any way you can detect
what's right in front without illuminating it yourself -- with light,
sound, or whatever -- and it's hard to do that and still remain stealthy.
So subs emit only when they have urgent reason to.
