Tides of War

I think that when the sub cuts its engines or runs silent, the little dot that was once the exact, or very close to location of the sub should start to grow. as in the fussy little dot gets bigger and bigger until it just disappears and the sub is lost, it is still possible to find the sub, but there would be a larger area for it to be located.

Believe it or not, that's pretty much how it works now.

The sphere doesnt get very big on mine .........

Hence the pretty much....

Wouldn't you just go for the center of the dot anyway? As it is, the dot stays small, but only shows a subs last known position, so it might have slowly crept away.
