RealBathy™ depth contours
Raymarine’s RealBathy™ feature allows you to record bathymetry data and
create your own depth contours.
When using the RealBathy™ feature, new contour lines are drawn in realtime
on the screen based on your transducer’s depth readings. Color shading
is used to reflect contour depths. The bathymetry data is recorded to the
inserted memory card.
RealBathy™ requirements
RealBathy™ requires the following:
• LightHouse™ vector based charts.
• MicroSD card with sufficient free space to record the bathymetry data.
• Distance between waterline and your transducer (item 3 in the below
illustration).
1. Waterline.
2. Water depth below transducer face.
3. Distance above the bottom face of your depth transducer to the waterline.
Creating RealBathy™ depth contours
RealBathy™ depth contours can be created in realtime as you travel.
