there are many different methods, I would suggest using as many as you can to cross-check:

1. your soundman will call out a speed when he reports on a contact, i.e. slow speed, medium speed. There are some threads in the SH3/4 forum which explain what this works out to in game terms, I believe "slow" works out to 6-9 knots. This gives you a range of possible speeds;

2. take two separate range and bearing on your target, at least 5 seconds apart (the longer the better), click on the"estimated speed from range observations "line (see screenshot above in step #5) and the XO will give you a speed estimation. Be careful with this though, it is often way off if your range estimation was incorrect;

3. measure from the map as follows:

a) take a first bearing and range reading of the target and plot it on the map (point #a);

b) wait 3 min 15 seconds (use the stopwatch);

c) take a second bearing and range reading of the target and plot it on the map (point #b);

d) measure the distance from point #a to point #b on the map, remove the last two digits from the distance measured in meters, this gives you the speed in knots (i.e., a ship moving at 10 knots will travel 1,003 meters in 3 min 15 seconds).

If the speed in 1,2 and 3 matches, that is the correct speed.

I am pretty sure stadmeter measures from the top of the stack. Not the mast. If you measure it that way your numbers are much closer to that of the ruler. The challenge for me is getting the correct "waterline" as you can move the scope up and down

[Frederf]

The stadimeter's expected height varies from ship to ship with no understandable pattern. Sometimes it's the mast, sometimes it's the funnel, sometimes it's something else.

The scope being able to move shouldn't matter. The horizontal center line (aim) on the scope has no connection to using the stadimeter which operates strictly on the angular difference between two images.

Same here

From the tutorial mission alone, I found that one ship required me to use the top of the funnels, and another to use the top of the masts. And one ship was somewhat inaccurate no matter what reference point I used... (like a 200m error when it was only 1km away).

As has been said, the position of the horizontal marking on the scope doesn't matter as it did in SH3. You could be in the heaviest of seas and still use the stadimeter with good accuracy - if only it worked as it should. I've been waiting for this feature since SH3! (Didn't get SH4) Still waiting

Speaking of manual calculations, I need to find myself a nomograph to print out. Easier than adding one to the SH5 map. Anybody have any links to hand? I'll go pay Google a visit in the mean time.

done, edited the first post to add a link to the pdf file.

I have followed this to the T and my torps still miss my target by a long shot, not even remotely close

fixed
Seems I was inputing the angle wrong, and was putting it as 45 degrees instead of -45 etc

[Seefer]

Regarding the talk of stadimeter problems, just how much error are we talking about? Are the errors grossly inaccurate compared to the accuracy achieveable with the real-world instruments? If so then yes, this is an example of a ludicrous bug that is probably the result of lazy design and shoddy quality control and should be fixed immediately consdiering the importance of range-finding in a submarine simulator.

However are we sure that the errors in the stadimeter are in fact representative of the error bars you'd see in the real world. After all, an optical range finder is not like a laser designator

I'm just curious to know the severity of this alleged stadimeter problem from others with more knowledge of SH5 than I have so I can add my voice to the calls for it being fixed pronto.

It's a bug. Mast Height is stuck at 20 for all ships in stock. This problem has been fixed with TheDarkWraith's NewUI + TDC mod which now pulls the correct mast height from the config files when you ID a ship and fixes the standimeter.

Hi, I'm new to this forum and the game, and wanted to firstly say thanks for the tutorial, trying to get into manual targetting since the old days of easy SH3 firing are long gone! Prob a noob snag,but when i enter the angle on the bow according to your calculation it always resets to zero, or defaults to whatever my watch officer thinks. this means my eels always head for the ship now rather than where it will be.am i just being a fail?
thanks

Not your fail. This is a known issue. I believe the AOB is reset every time you update the other information in the TDC. It needs to be the last bit of data you enter.

Happy hunting!

If using my UIs mod you can prevent that from happening by clicking the red buttons attached to the TDC dials

Ok this really will be a fail,where can I get this and how do I install it?thanks

Homskipanda, the last screen is the periscope screen. It comes up when you click on the observation or attack periscope.
