The TDW interface with the Manos Scope i used in all my video tutorials... see them and you will see i never miss a target... the problem is that they are too acurate

... and as tdw said is very important to use the corect scope mod patch for your rate in game... i will go back at tutorials soon when i will have some free time
btw... where you readed this?
EDIT: I made a misteake... i tested between 15 and 165 degrees and i had very acurate readings using U_jagd chrono.... if the AOB is between 0 and 15 or between 165 and 180 you must to start the crono in front of ship and stop the crono in the middle... but i did not had all the time the corect speed readind results... so i take the speed of a ship only between 15 and 165 degrees... see this tutorial from here:
