How do you know which new valve for moving magnet bar , sir ? and you can not move Mag Heading to Gyro Heading 'cause we have Geomagnetic Deviation of that area . pls tell me . thanks
what i dont understand is how do you know to what value to adjust the heading? you say true heading is 097, but how do you know that if the magnet heading shows the not adjusted values?
