DeLorme PN-40 Earthmate for sale in GPS technology and devices Posted October 22, 2013 Selling our Delorme Earthmate PN-40. This was our first Geocaching GPS and has worked really well for us as total beginners, the only reason we are selling it is because we are moving to the UK and Delorme don't supply maps for Europe. Unit is boxed with a case, 8 GB SD card for maps plus a soft protective case. It has maps of the USA, Canada and Mexico with it plus the Topo 9 software. It's in great condition, small scratch on screen which is only visible when it's turned off (from before I got the case!). Asking $125 shipped within the USA.
