@CaptaimDeadlySniper I look at the target and use the TDC to enter the info.

how do u work out ur aob or do u use the tdc instead?

@DarkRaven I appreciate your time and effort and didn't want to ask for something like this, but if you happen to stumble upon this, it would be great to see it in mod. Cheers.

@Alex Paen By default, the target parameter window does require a target, soft or hard locked. This mod disables both types. I probably could get a workaround for it, but that's going to be low on my modding todo list, so very much no promises.

I was wondering if the game would allow opening/closing the data entry panel under the periscope without lock on? This would be an interesting solution as an analogue of the captain's voice commands to the officer with the TDC. And it would not be tied to the target, it could be opened at any time

@Colonel Kurtz The chonometer / stopwatch is still available from the resource bar next to the ship control buttons. The bar and its components toggle visibility with the 'Alt' key by default. AFAIK that is vanilla behavior.

Am I the only one suddenly missing the option for stopwatch in periscope sight mode?
A bit annoying having to rely on a real stopwatch :D

I made the mod that changes the UBOAT stadimeter units to milliradians.
Here are some great sources on how the periscopes worked:

Bottom line: there were no split view rangefinders on WW2 German submarines. US subs? Sure. WW1 German subs? Maybe.

In UBOAT this is a cool feature that the player can choose to use, or through mods that give us calibrated reticle angle markings, use historical methods of determining the range instead.

@ReKoy I understand. I still recommend a periscope mod in that case. My More Accurate Periscope Sight has a vertical mrad scale and I think Hard's HardScope also has one.
If you absolutely require a stadimeter with this mod, I'll add an option when I next update it, but for now you can open PeriscopeUIPatches.cs in a text editor and any entries with stadimeter in the name you can change false to true. That should enable it. I'm not at my computer ATM, so if it doesn't work I can't help until later.

> the stadimeter was on the type 7

That is not true. A stadimeter requires a complicated adjustable dual mirror setup, something that is hard to gauge even without having to cram it into a metal tube. The lens system in a periscope of that era had no capability to house such a system. If anything, they could've had a handheld one.

Just use a periscope mod (you're at the right place with DarkRaven) and calculate the range using the vertical markings. It's virtually the same procedure.

Also, accurate range finding is not something a U-boat needs to have, you're not firing at something 10km away with a ballistic trajectory, like a surface warship would do.

@DarkRaven Let me try to explain what I mean. There is another mod that shows the stadimeter readings in millirads, and with this number + mast height + attack disk you can find out the range of the target, the stadimeter was on the type 7

@ReKoy I mean I could enable it, but it would be useless. It determines distance by comparing the angle of the stadimeter to the target's height. But there is never a target, since you can't lock on. So without the height, the tool can't make the comparison and the it doesn't work.
If you want it just for the angle, you might be better off getting one of the periscope mods that are available and using the reticle markings, if you're aiming for realism. Though I don't know why someone would want this mod without the desire for more realism.

@DarkRaven Could you make a version or modification via datasheet so that it would be possible to disable locking, but leave the stadimeter, for example?

@Drexack you beautiful human being, your page is a dream come true, thanks

I had already been using No Spoilers but this kind of refines that and cleans it up a bit. Great job. Cheers mate

@1577511169 You input the data into TDC manually. If you have an officer working the TDC, there is a red and green button the left side that lets you access the TDC from the periscope/UZO.

@BobbySopor Allow me to answer this. Click the workshop page of DarkRaven and download his realistic sights mods. I made a reddit post with tables that includes a distance table for this sight, as well as his other sight mod. Lastly, make yourself aware that accurate distance measurements are only needed for high gyro angles. If you fire at a target that is between your 315° and 45°, you can get away with an educated guess.

so i played with it and its very interesting because it doesnt feel so arcady anymore, but i realized my beloved stadimeter is gone so now i have to do the math myself, but i find the markings in the periscope a bit confusing. can you recommend a good mod for realistic sights?

I don't understand your description. If the measuring tool is disabled, how can I control my torpedo?

Yes and access to flood / launch torpedoes.

do i still have the identification book?
