8.9 RealBathy™

You can create precise personal bathymetric charts in realtime using Raymarine's RealBathy™ feature.
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 depth, with the darkest shades
signifying the shallowest area. The sonar data is recorded to the inserted memory card.

Requirements

The Realbathy feature requires the following:
• LightHouse™ software version 3.9 or later.
• LightHouse™ vector based charts, that include tide station information for the location you wish
to survey.
• MicroSD card with sufficient free space to record depth and bathymetry data.
• You must ascertain the distance above the bottom face of your depth transducer to the waterline,
as shown in the following illustration:
