ADCP compass calibration is required to not only correct for location specific magnetic distortions (i.e. distortions caused by changes in the earth’s magnetic strength at various locations), but also to correct for the introduction of new materials with a magnetic signature, e.g. mounting hardware.

When should I perform compass calibration?

Compass calibration is site/installation specific, and therefore should be performed by the user prior to deployment.
