Question about using the U-jagd

BritTorrent · 01-02-21, 08:46 AM

Hi all,

I've just watched a tutorial about using the U-jagd chronometer to gauge the speed of a target. It sounds pretty simple, just measure the time it takes for the ship to transit the vertical periscope line and then cross reference the time on the relevant length line.

However, does this only work for certain angles on bow? Are there any conditions where this method won't work?

Thinking about it, if you've got a really shallow or really steep wide angle on bow then surely a ship of given length will take less time to transit your scope than it would with a AoB of 90?

Is the U-jagd only accurate for for AoB of 90? Or is it just a case of being less accurate the further you get from 90?
