You can enable the True Motion feature on the RealVü 3D Historical sonar view only when using a compatible transducer, such as a Panoptix™ PS70-TH.

The True Motion feature on the RealVü 3D Historical sonar view uses data from additional sensors connected to the chartplotter, such as speed and heading sensors, to show a more geographically accurate historical view.

To enable the True Motion feature on the RealVü 3D Historical sonar view, select Options > True Motion.
