If the magnetic North arrow in the declination diagram is to the left of the north gridline, this indicates that magnetic North is west of true North. To obtain a compass reading that aligns with true North, you would need to add the declination angle to your compass reading. Therefore, if the magnetic North is to the left, the compass reading should be adjusted accordingly to the right (east) to compensate for the declination.
If the magnetic North arrow is to the left of the North grid line in the declination diagram, you should subtract the declination angle from your compass reading. This is because the magnetic north is to the west of the grid north, so you need to adjust your reading accordingly to navigate accurately.
The declination diagram is typically located in the margin of a map, often in one of the corners. It illustrates the angle of magnetic declination, which is the difference between magnetic north and true north at a specific location. This diagram is essential for navigators and map users to accurately interpret compass readings in relation to the map's orientation.

A magnetic compass has a needle mounted in a way that allows it to turn freely. Tis needle always lines up with Earth's magnetic field and points toward magnetic north. The needle is set over a diagram that shows east,south, and west. By knowing which way is north, a sailor can find the other diections.

displayed on a nautical chart that shows the amount and direction of the magnetic declination for a specific location. It is used by navigators to correct compass readings and determine true north.
If west declination(ie: magnetic to left of grid)_formula= GN>>>MN You add MN>>>GN You subtract. Just the opposite if on the other side(East declination)

There can only be one Cartesian North.
