You should play with feet, yards, and miles in an American submarine
The red arrow is periscope depth in the shallow gauge. It's test depth in the deep one.

Yes im using metric system.
No other mods installed except TMO 1.9.

This is the spot where i need to take measures right?


Yeah im pinging the right ship, this is the last ship in convoy, escort is in front of him.
Somethings not right here, i'll try switching to miles.

3 minutes show target speed of 21 knots, and again 2k meters:


I hope that they didnt spot me and speed up, but i dont see the escort turning nor morse code flashing, so it looks like they didnt.
Looks like the stadimeter doesnt work like it should work for me.

btw i just saw this, the scale on the stadimeter says "Range in yards"

Looks like you are using the stedimeter right.

The three minute rule is very good for speed but since you are using metric the rule is 3 minutes and 15 seconds not 3 min. even. That would give you a speed of more than 21Kn so I think your range and bearing data is off.

In your screen shot there is a circle of 2100 meters and your sub is outside the circle so the range to target should have been something like 2500 m. or so. In the second SS the PK shows 1136 m so something is wrong.

You shoot my 10° bearing shot and missed behind says that you had the speed of 8Kn. wrong. Using the auto plot speed thing is not very accurate. For a speed of 21Kn. put the scope to about 20 to 22° and try that.

You have picked a very tough target to learn manual targeting with 100% realism. Fast moving warship, clear sky and calm water.

You might try a single patrol and turn map contacts on and get the feel of manual targeting and how the TDC/PK work. That way you can check your firing solution on the attack map. Get a little experience and than come back and put the CV under.

I concur.

What is also strange is I have been raised in the metric system, so the US length units meaned nothing to me.

But I have learned to understand and use them using the game, and now I see the beauty of those units especially in the naval use.

Ok Magic, 3 minutes 15 seconds. That would give more than 21 knots, but hows that even possible when the target max speed is 21 knots ?
Above nav map picture is made using sonar, when im using stadimeter i measure 800m range and 8 knots.

Thats a big diference dont you agree?
800m - 2000m
8knots - 21 knots


Somethings wrong here, why am i not getting same values thats what i want to know. And which one should i believe in this case, sonar or stadimeter. Since im missing the target my guess is that the stadimeter is incorrect.

I think I see the problem?????
Try taking the stedimeter reading on the flight deck instead of the top of the mast. 16 meters is about 50 feet and that is way too low for the mast high, but sounds about right for the flight deck.

If there is some other ship you can get a fix on like a DD try that one also.
Some carriers use the deck but all DD will use the top of the mast.

PS if you are pinging warships to get range I predict a very short career in TMO1.9.

Yes you are right, flight deck is the spot.
Im not pinging warships, up close, only from distance.

Thank you guys for your help
