You're so obsessed with "range". I'd trade a good target course and speed
estimate with laser precision range anytime. WHAT?!?. Actually I'm trying to improve my "Bearings-Only" techniques. They come really handy in the pre-radar phase of the war and in the "final approach" where you'd probably wouldn't be able to use the radar to confirm and refine the target's data. Eventually, if you're close enough, 0-gyro angle torp shots remove the necessity for extreme range accuracy (bit still you need a good course and even more a speed estimate). Active pinging is not included in my gaming style at the moment but I'll be sticking to "Contacts Off" permanently.
My (limited) experience with active sonar is that if the overall range to the target is "small" the readings are not bad. My feeling is that the game may have problems handling relative motion, Try multiple pings with the sub stationary and see what happens. Even better, try a "mission" where both target and sub are stationary at a known distance and see what's the active pinging result. Maybe even "calibrate" the thing at varius predetermined ranges and see what happens.That would be really useful to all of us.
