+<h3>"Modern" Garmin handheld GPS devices</h3>
+<p>
+Connect the GPS device to your laptop (or the expo laptop) using the USB cable. A folder will open on the laptop showing the contents
+of the device. 
+You will see a subfolder called "GARMIN". Open the folder "GARMIN" and copy the file essentials.gpx which you 
+downloaded into that folder.
+<p>Even modern (2019) Garmin GPS devices use this old style mini-USB socket. So you will need the special cable that comes with the device. An ordinary phone USB cable won't work.

+<h3>Very Old Garmin handheld GPS devices</h3>
+<p>
+These need the Garmin communication protocol to import cave entrance locations (waypoints) and paths (tracks). 
+You can't do it by simply copying files.
+This means that you need special software on your laptop in addition to a USB cable that 
+connects your laptop to the Garmin device.
+
+<p>Once you have the right cable and connected your handheld to your laptop:
+<ul>
+<li>On a Windows machine, use "GPSbabel for Windows" which has an easy to use graphical user interface: 
+<a href="https://www.gpsbabel.org/download.html">download GPS Babel</a>
+<li>On a Linux machine the core gpsbabel command line utility is probably already installed; 
+but there is no simple, easy to use graphical interface. 
+Instead you must use other software such as QGIS or Viking (download using your usual Linux software installer) 
+which uses gpsbabel to talk to your device. 
+If this doesn't work then there are no useful error messages from Viking.
+</ul>
