Can I do a large dile in then swing the the boat for deveation?>

Has your vessels compass every been professionally swung to know it is accurate? Did you do your calibration circles and have it take..? Do you have any ferrous metal objects close to the flux gate? Pots, pans, tool bags, speakers etc. etc..

Even when you get it swung and calibrated they are rarely if every spot on with the ships compass but you can get them darn close.
