[REL] My tutorial for 100% realism manual targeting

[CaptainNemo]

Can you tell me which Recognition Manual you are using? Looks great!

[I'm goin' down]

It worked for me, and I am brand new at auto targeting!!

[I'm goin' down]

I have two issues.

First, I never seem to get the correct range. Usually, the 'X' on the attack map is closer than the target by several hundred yards. What am I doing wrong?

Second, the white line runing from the 'X' is going in the wrong direction. I assume it is supposed to adhere to the target's true course. I also assume I must be setting the AOB wrong, which should improve with practice. Am I correct? What do you suggest?

The tutorial is a good one and I have sunk a few ships notwithstanding the mistakes I have made.

The distance is nearly impossible to get properly with the stock game stadimeter. But you can put a reasonable close thing, and it will work OK (Distance is important mainly if you shoot with large Gyro Angles). There are two mods you can install to improve the measuring of distance: The fix by CaptainScurvy for better stadimeter measuring, and the radar mod by Nisgeis, which adds a digital readout of distance to your radar, giving you exact ranges.

I used your manual targeting tutorial, but usually had major problems with the range, and the direction of the target was usually inaccurate. But the concept of aspect ratio is quite interesting. Before I delve into your new tutorial, I want to point that the ship centered accuracy fix (SCAF) mod makes finding the range, aspect ratio and angle of bow a simple matter. Instead of determining range by matching up to the target's mast, you match up to another part of the ship (e.g., the smoke stack), so it is not as difficult as the task of matching up to the top of the target's mast, which is difficult to pinpoint at a distance. And you do not necessarily have determine the aspect ratio for accuracy.

I used it for the first time today, and the white "x" and white line showing the target's course on the Attack Map were on target. I mean exactly on target. (Maybe I got lucky). As the target moved into firing range the white x fell astern stlightly, which I attribute to a possible miscalcualtion of the target's speed. I fired and missed four shots to slightly to the stern of the target, but the markings on the attack map were where they were supposed to be. My ship only permitted slow torpedoe speed, and I do not know if that played a role in missing the shots. When calculating range on the stadimeter the trick appears to be matching the bottom of the waterline beneath the bottom of the top ("movable") target to the designated spot (i.e. the smoke stack) of the actual target.

If I strike out when I try it in the next few days, I will post a retraction. By the way, I delivered four torpedoes into a carrier yesterday, and although it made a major turn to port, it did not go down.

I had already read the Hitman tutorial. I thought it was a newer version. Anyhow, I want to follow-up on my previous post. I used the ship centered mod (SCAF) this evening and was able to calibrate range and angle of bow on a large modern split frieghter travelling at 10 knots at a range of about 1,000 yard at a bearing of roughly 350 degrees. The whte "x" and the white directional line on the attack map were about 50 yards above the target, but otherwise precise. I fired four torpedoes. I recorded the attack. The first torpedoe passed under the bow of the freighter, so I must have set it to run at too great a depth.
The other three were hits on the bow section.

The benefit of using the mod is that you do not need to calculate the aspect ratio. It brings satisfaction to work out the correct aspect ratio, but it also a pain in the rear because it can be time consuming.

I have one correction to my previous post. When calculating range, line up the shadow ship with the mod's predefined point on the target and make sure that the bottom of the shadow ship's keel is touching that preddefined point. SCAF modifies the ship manual and the predefined points for each ship are highlighted in red. Read the instructions when you download the mod.

I f you don't use the mod, Hitman's tutorial should work better than trying the impossible task of lining up the shadow ship with the high point on the target's mast.

thanks a lot it is a very important material

I'd like to give this a try also. Has anyone got the file to upload it to Subsim?

Did you try looking to see if was already uploaded to Subsim?

just few things.

1. Its not required to put the ship on the horizon line when taking the range with stadimeter. Thats how it worked in sh3. In SH4 all you have to do is match the waterline with the masts. There is no connection with horizon line. Makes taking range a lot easier in rough seas.

2. Aspect Ratio is one method to get the AoB. However historicaly rarely used due to many reasons. At first you must know the aspect ratio, that was not always the case. Then it was less acurate then it appears in sh4 because it was very hard to hold the scope on one place with a boat being shaked around in rough sea. And after all it requires to have the periscope raised for to long time.

Altirnatively you can take two position marks and make a plot. That will not only provide the course (which can be converted into AoB easily) but the speed also.

Basicly youre doing it anyway. When you get speed you also have course information. Just tune in the course in TDC compas and you have your AoB. No calculations needed.

Yeap, there is on guy who knos how to use the TDC and KP, though KP degreads rapidly. I learnned how to use it from your video tutorial, though i do not take just two measures, the first on when i idenity the ship cause is ussually pretty far still and is not very accurate, i take 3 4 or 5 depending on the situation although the longer the time between measurements the better, is also true the farther the ship the worse is range accurate. I found a way in between these two parametrs that usually works for me.

The tutorial can be found in the subsim download section. I am too lazy to post the link.

Are you mocking me, or have you forgotten that subsim limits your downloads unless you begin paying money?
