Simple proof against the flat earth model

Gyroscopic compasses always point in the one direction and are used in many advanced navigation systems. This overcomes the assumptions of navigation in the UN map model.

Gyroscopes are consistent with Newton's laws of motion an are not affected by magnetic fields.

You know the Earth is probably flat like a Gyro sandwich.  Then again the Earth would be round if you are refering to the spinning Gyro.
Sorry Man .... I get bloody confused.
