Come on you have never done that?

I took three ships out without touching anything but the rudder. Manual set up. Scope set to zero. Most likely 1000 yards or less from the targets. All I did was turn the boat and fired 6 fish into three targets sinking all three.

You lose about 5 seconds for speed run up so you just lead the target. It is the same on radar or sonar bearing shots. You know that receiver has to go around so you never shoot at the target because it will always lead your line of fire. You can't sit at the sonar and at the scope so you learn to lead the target.

I took out the Yamato in a typhoon with an average yardage of about 1000-1500 using radar alone. You do not need math when you know how the devices your using work.

It is like using the Israeli instinctive shooting method. You just know where it is going.
