[CA] [CA11] Installing evo400 on a steel hull sailboat

Maurizio,

Low current carrying conductors should not pose a problem for magnetic north seeking devices. However, high current carrying conductors can create magnetic fields. Should one have a concern that the considered mounting location may produce high detected levels of deviation, then it would be considered to be a best installation practice that the EV-1 be installed in a temporary fashion and that following execution of the Dockside Wizard that the vessel be taken on the cruise to determine the maximum detected deviation. When cruising, all devices having cabling which passes through the mast should be switched ON and continuously operated until the cruise to detect deviation has been completed. If the considered installation location is found to produce an acceptable maximum detected deviation, then the EV-1 may be permanently mounted, a Pilot Factory Reset executed, and Dockside Wizard re-executed, and cruise to determine deviation executed again.
