Windsond now adds support for OziExplorer. Since before, Google Earth could be used to visualize the movement of sondes during soundings and to see the predicted landing locations. Now OziExplorer can be used as an alternative. OziExplorer has better support for offline maps which can help if operating without an internet connection.
OziExplorer is a commercial mapping application, also available in a free version with limitations, and a trial version. The support starts with Windsond software 1.52. Enable the support in the Settings dialog.
