DocumentationDownload Users ManualUsers Manual (Installation and other Users Information) Magnetic Model Updates (Not applicable to SP3002D)Sparton digital compasses use a spherical harmonic model to calculate the magnetic variance. This variance is then used to adjust the magnetic heading to indicate a true north heading. In order to retain accuracy, the magnetic model must be updated every five years. A software program is available on the supplied CD (sent with each digital compass purchase) that will assist in downloading new coefficients into the Sparton digital compass. This only affects the calculation of true heading and does not affect the magnetic heading accuracy. Additional magnetic model update information can be found within the Sparton Digital Compass User Document in the Magnetic Model User Updates section.Download the Sparton Digital Compass Magnetic Model Software Upgrade - .cof file Please download the following file, if you are unable to save the software upgrade to your computer.
