SonarChart Live Overview

With a Navionics+, Update, Platinum Plus, or HotMaps chart card having an active Navionics Freshest Data Updates subscription present within the memory card reader of a MFD running the latest LightHouse II or LightHouse 3 software, Navionics SonarChartâ„¢ you can easily enhance the sonar bathymetry for your area and create high resolution bathymetry maps for bodies of water lacking detailed bathymetry. SonarChart Live cartography is displayed in real time on your MFD, using your system's depth transducer.

When Sonar Logging (LHII: MENU->PRESENTATION->DEPTHS & CONTOURS->SONAR LOGS; LH3: MENU->SETTINGS->DEPTHS->SONAR LOGGING) and the SonarChart Live (LHII: MENU->PRESENTATION->ADVANCED OPTIONS->SONARCHART LIVE; LH3: MENU->SETTINGS->DEPTHS->SONARCHART LIVE) features have been enabled the Chart will begin to display the path through which sonar is being logged, showing increased bathymetry detail within the path taken by the vessel. The background color of the SonarChart Live cartography layer will be white in depths greater than sixteen feet. Depths lest than sixteen feet will be rendered in colored shades transitioning from pink to red to denote shallow water. This depth threshold is not presently user configurable.
The screen images below illustrate the coloring of the SonarChart live chart layer.





When seeking to maximize the accuracy and detail of the SonarChart Live bathymetry, it is recommended that a pattern search (see image below) be performed over the area of interest (reef, wreck, submerged creek bed, drop off, etc.).
