I put a question about manual targeting in the SH5 TDC Tutorial thread but I don't think anyone has seen it. Here it is. Hoping someone can answer my question. I watched your tutorial on manual targeting but I still have trouble with AOB.

I'm used to SH4 which means I am used to the position keeper. Enter Uboat...no position keeper obviously. So what is the correct order of entering data into the TDC? I ask because every time I put my scope down ( to avoid detection) and raise it again to take a new bearing/range measurement, my AOB resets itself.

I've been doing this

1. Get target's speed through visual observations (using the 3min 15sec rule...mark target's position, wait 3 minutes and 15 seconds, mark target's position again, the distance traveled in meters corresponds to speed.)

2. Take bearing/range readings using stadimeter - enter them

3. Enter AOB (measure using navmap protractor tool).

4. Take one last range reading before firing (Note: I usually have to reset the AOB at this point because the last range/bearing reading seems to reset my AOB dial.

Am I doing something wrong?

Also, is the 3 minute, 15 second rule for taking speed measurements correct? In SH4 it was an even 3 minutes but when using meters as opposed to yards I believe it is 3:15.
No you are not doing nothing wrong... it is like an bug... after you use stadymeter the AOB is reset and is going back at the last locked value... i spoked about that with TDW and he will fix this soon
About the 3.15 methode the Bilge Rat teached me this:

''1) identify target and determine mast height;
2) measure mast height in number of Horizontal Bars on the scope;

you can then measure the range based on a formula, for example with Arclight's MRP, the formula is:

1.5x - MastHeight x 100 / horizontal bars = Range

6x - MastHeight x 400 / horizontal bars = Range

for example, a Liberty Ship has a mast height of 27.1 meters, if the measured height is 4 bars at 6x, the range would be 2,710 meters.

i.e. 27.1 x 400= 10,840 divided by 4= 2,710 meters.''

Honestly i never tryied the 3.15 methode
