2. The correct connecting sequence is as following:

    If you start MagNav, and then connect WiFi to the instrument, or if you connect WiFi to the instrument and then start MagNav, then you should receive data in MagNav.

    If you do anything to disconnect the WiFi, for example by rebooting the instrument, or by walking out of WiFi range, or by using the tablet settings to disconnect WiFi from the instrument, then you will not be able to see data in that original open MagNav session, even if you reconnect to WiFi. The app will not communicate to the instrument through this second WiFi connection.

    The solution is simple: close MagNav and then re-open it. MagNav will now communicate with the instrument (as long as the WiFi is connected).

3. This is a common feature in MagNav, which applies to all other MagNav products, such as G-864.

New releases of the MagEx and G-864 magnetometers include automated updates of instrument software (the embedded sofware, sometimes called firmware) into the G-864 MagEx instruments. This feature eliminates an additional installation process and reduces the need for customers to track software versions and compatibilities.

How does it work?
When the MagNav app connects to an instrument, it determines whether the instrument's software should be updated. If an update is available, MagNav informs the user, who can choose to update the software or to wait until later. If the user agrees, MagNav sends the update to the instrument, which installs the software and restarts. After the user reconnects the WiFi and restarts MagNav, the customer enjoys the benefits of the new version.

If the automated process is not available for any reason, the existing standard install process, using a USB, will still be available to install software on the instrument,

One last time for G-864 customers...
Existing G-864 customers will need to run the manual install one last time, because the instruments shipped before the introduction of this feature can't execute the automatic upgrade. After that final manual update, those G-864s will support automatic udate.

Does this also automatically install new versions of MagNav?
No, this feature does not automatically install a new version of MagNav; MagNav will still be installed onto the tablet from a USB drive. This feature involves the elimination of the separate, additional installation of software into the instrument.

1. Open Google Earth Pro. Navigate to your survey area and click “Add Path”.
2. Move your cursor and left click to define the outline of your survey area. You can rename your path name and click OK.
3. Select the new path created and right click it. In the pop-up menu, click “Save Place As” to save it as a kml file.
4. Open the Survey Manager. Load an existing project or create a new project. Inside the project, create a new survey. Set up other preferred parameters. Click “Select Route File” and load the saved kml file. Make sure to click “Save” before exiting
5. Plug in a USB drive and copy the project (.dbt file) to the USB.
6. Eject the USB from your computer to make sure it can be safely removed.
7. Turn on the instrument and the Getac tablet. Make sure the wifi is connected.
8. Plug the USB drive into the Getac tablet.
9. Open the MagNav app. Click “Import Project” to load the project (.dbt file) from the USB.
10. Enter the project and enter the survey. On the Navigation page, the path created in Google Earth will be displayed, which can be served as guidelines or outlines for GPS surveys. Marker points can be created similarly for marked surveys.
