Navionics SonarCharts
Navionics has greatly improved the resolution of its electronic charting of underwater landforms with new high-definition data that draws true bottom contour lines. Created by integrating existing hydrographic data with sonar logs received from the extensive Navionics user community, these new SonarCharts provide up-to-date detail with a level of accuracy not previously available. This new software is compatible with Platinum+ cartography packages for iPad and iPhone at retail prices of $5.00 and $10.00 respectively. A beta version is now being field-tested for their WebApp packages and should be widely available shortly.
