Mike,
Thanks for your post. The restocking fee would only apply to the USB GPS sold as part of the bundle and would be limited to $12. You would also be welcome to return only the EarthNC software for full refund and keep the GPS for use with other programs (as a standard NMEA compliant GPS, it will work with most other systems).
To your additional questions:
1. You can view a screen shot of the north end of Lake St Clair HERE. Depths are shown by the shaded numbers (in feet). Depth information is sourced from the official navigation charts and has the same density.
2. You are correct, while you would not have charting for inland lakes, the GPS tracking / satellite view will still work.
3. Data stored is based on where you have most recently ‘explored’ in Google Earth, including to what zoom level. In basic terms, if you ‘preview’ your boating trip while connected, Google Earth will automatically save those areas to the local cache.
3a). Coverage area depends on the zoom level and image resolution, but 2GB is generally more than sufficient for a full day of boating and often more.
3b). This is based on the level of zoom used while ‘previewing’. The closer you zoom into an area and allow it to load, the more detail it will have offline (and also the more storage required).
3c). We have an article in our Google Earth Tips and Tricks Forum about how to make multiple cache files.
4.) We are always working to expand our coverage. Obtaining inland lake data takes time as it is often held by local governments or private organizations.
It sounds like you have explored the website well. The EarthNC bundle is a combination of our EEarthNC Plus Vector Charting, EarthNC Raster Charting, with the addition of a NMEA compliant USB Globalsat GPS and GooPs Pro GPS to Google Earth software.
Please let us know if you have other questions.
