B.Aligning the Stadimeter where the Stad was just touching the HIGHEST part of the target i.e the mast head?
I have used both and my aim is still crap!!!....Just want to know what is right for stadimeter range input.

Deep six

its hard to get a exact estimate. but tbh you dont need one. Thats why you fire in spreads

but you can try it out yourself. I cant do it any better then you can. Run a game with manual tdc and map updates, you can then try wich alot of different settings and see how it affects your position keeper marker.

started a second career today using manual TDC and things did not go nearly as well as I'd hoped.

The first thing I noticed was that virtually all of my range estimations (using the stadimiter) were well short of the target's actual range. I think I'm using it correctly: setting the horizontal line in the periscope along the waterline of the target, selecting the correct ID in the recognition manual, bringing up the image splitter/stadimeter, and placing the waterline in the top image on the top-most point in the bottom image. At first I thought I was mis-identifying the targets, but the sampan fishing trawlers couldn't be misidentified because there was only one with the correct number of sails.

The other thing I noticed is that, over time, the position keeper appears to get confused as to where the target actually is. The only thing I can think of is that my constant re-configuration of the target info is confusing it?? The lack of a functioning chrono is certainly hurting my speed estimates, but I think I can overcome that. I've got the 'turn off map updates' off, so I'm cross-referencing where the target appears on the map with where the TDC thinks the target is (white X with a tail indicating direction of movement).

Any assistance would be greatly appreciated!!!

Did you check what measurement units the stadimeter is giving you?

How would I check that? Anyone got a quick conversion from yards to nm?

Oh, and the stadimeter measurement is supposed to be done while the scope is at high magnification (although this would lead to over rather than under reading).

r.

I am using imperial measurements and I would expect that the proper information is being passed from the stadimeter to the PK. I am using high-magnification.

I know one other poster suggested it: can we get a picture of the correct stadimeter alignment? I'm guessing it's something I may be doing incorrectly, as my ranges are usually off by about 1/3rd.

2000 yards = 1nm

There is ~2000yards in one nautical mile. The Imperial system actually works with nautical ranges quite well.

Whats up with the auto-solution? I'm not exactly sure why its not working...But i'm hardly hitting ships here!! At the moment I'm using the torpedo school to debug the situation. I lock up the cruiser. I wait till the carrot is green. Set torpedo speed at high. Set fuse to contact and depth to about 10 feet and open the door. I shoot but the torpedo goes way left or misses...WTF? Shouldn't the auto-solution work dead center every time?

I'm getting so frusterated with this game...It's almost unplayable...But it LOOKS SO GOOD!!! Waaahhhhh.....

Dizoak · 03-25-07, 10:48 AM

leave your torpedo's on slow, they have more range and you can still hit a fast moving target with one. try to lead the cruiser a little bit, give yourself some steam and aim for shots at no more than 1400 meters range. remember to use the position keeper to update your solution JUST before you shoot. (also open your tube door before you shoot)

i do it in this order just to make sure i dont forget a step: lock target-open tube-do your torpedo programming (depth, set pistol, speed (if needed))-hit position keeper-depending on your tastes and the range to ship you might wait here and keep updating the position keeper-launch your tube. just rinse and repeat for any other tubes you want to shoot at the same target (just remember that if you switch tubes, your door will close and you have to reset all programming on a torpedo if you switch tubes before you shoot)

hope that isnt too confusing. good luck mate.

rulle34 · 03-25-07, 12:06 PM

Sorry, but I have read all the info about this and still can´t understand how to calculate speed in manual TDC. I hav used the navimap and mesured the time between two known points, but it could be done using "left click on the clock icon in the data tool" as it says in the manual. Can someone explain this to me in a better way. Im probably stupid but I can´t get it to work.
Please...

gnirtS · 03-25-07, 12:17 PM

Bug in game, Auto speed measurment isn't implemented.
Use the chart method for now.

Shrap123 · 03-25-07, 01:01 PM

I really don't want to use the point and shoot option where it's all done for you nor do I want to sit there and do math or guess randomly. Is there another way or am I SOL till they fix the chronometer?

dangchang · 03-25-07, 01:18 PM

One way to get the speed of the target is via the following.

1. Look for the ship you want to target on your map and get the CLOCK ready.

2. Take the pencil tool and place a marking towards the front of the ship.

3. When the ship touches that mark, start the timer and wait TWO minutes.

4. After the two minutes, place a marking where the ship was after the two minutes.

5. Use your ruler and connect your two markings and record the nautical miles.

6. Multiply the NMs by 60, then divide by two. That's the speed.

Example: (.4nm x 60) \ 2 = 12 Knots

Another example: The Mogami in the torpedo training mission moves at .3 NM for every two minutes. .3 x 60 is 18. 18 divided by two is 9. The Mogami is moving 9 knts.

I put auto aiming on to see what the speed really was.

9knts.

This is of course if you're using map contact updates.

Yup, the Mogami moves at 9 knots, and your measurement technique is right on. But if you enter 9 knots into the TDC you will consistently hit the cruiser, but well aft. Yes, with the outer door open before the shot, updating just before shooting, and really fast fingers. This error is part of the central mystery with the TDC. I have to enter 11 to 12 knots to get him amidships. Still no good explanation as to why.

On the TDC dial in the upper right it the button on the bottom on the far right. Just spin the dial and hit the arrow up top to send. The timer button will not enter a speed.

NefariousKoel · 03-25-07, 01:24 PM

I use two methods depending on how fast I need to shoot.

1) 3 Minute Method -

Mark contact's location and start the stopwatch running (or, if show on map is off, then mark range and bearing on nav map & start timer). After 3 minutes, repeat the process for his new location. Measure the distance between the 2 and multiply by 20.. (or multiply by 2 and take out the decimal point). This is the speed in knots.

It has an extra added bonus of giving you a decent heading of the target if you extend the line through the second one too. This can also help you get an AoB estimate if you measure from the line in front of the target.. to the target.. and point at your own ship to get the angle.

2)Quick shot Table -

The table in this thread is great for estimating speed at short ranges. I only use it if under 1750 yds range and near a side shot for the 10 second estimation.

The table is in this thread: http://www.subsim.com/radioroom/show...timation+table
I think Ims_oid worked it up but I could be wrong. It's helpful.

flyinj · 03-25-07, 01:37 PM

What is the most reliable way to reset the TDC and get a 'dead bearing' shot? I was engaging a docked frieghter in a port, and even though I set the target speed to 0, the torp wasn't shooting along the exact bearing of my periscope.

Also, I hate how the speed dial doesn't let you turn counterclockwise if you tick one past the zero speed mark. Is there another way to enter speed other than this dial?

set speed to zero, set torp spread to zero then go to the stadimeater and dial in a range and click the send to TDC while you have your scope on the ship.
