Icon2 Calculating speed close up with periscope

I'm having issues with trying to get speed manually. I know that when you are close up to a target you can set the vertical line of the periscope to a place and record the time it takes for the ship to pass from bow to stern of it to calculate the speed but this did not work when I did it and the speed keeps registering as 0 kts. Am I doing something wrong?

Hi there,

I'm assuming your using the notepad method for manual targeting. From memory I think this is the procedure for speed:

1. Lock the scope onto the ship (L), identify the ship in the recognition book and click the tick icon in the book to send that data to the notepad.

2. Click the stopwatch icon in the notepad. Wait about 15-30 seconds and click again. You might have to do the range and angle on bow first though. Note that the scope needs to be locked on for it to work.

Correct, you need range and AOB first. What’s happening is not what it seems - the game is calculating speed based on bearing change and not doing the “fixed-wire method” which times the transit of the vertical wire. This is clever of Ubisoft, as this was a method used as a backup (as was fixed-wire), albeit with a slide rule and not a magic notepad.

For that calculation, you need a range, an AOB, and time. 30 seconds to a minute should do it. And you need to keep the target locked in the scope as stork said.

So more time measuring means more accuracy? I see now, thanks for the help guys

At one point I did a writeup on how to incorporate the use of the notepad into a process, hopefully this helps too:
