And welcome fellow Gold hunter, while you fight with Mulberry bushes and leaches I fight with dust, Snakes and Golden Orb Spidies, and many hours of bush walking.
Regarding GPS's well I only use 2 early series Etrax's and a HP PDA " as I was among the few people in WA to run in car Navigation "Moving Map" way back then about 2000.
I have a M8 that runs a HN7 and was asked to see if I could get maps on it to work "I couldn't in the time I had "1hr" and it was a pain to use as well, another M8 whom I go prospecting with has an VMS which is also a pain but I managed to get My maps to work on his machine via OziExplorer, that really took some time but he can follow me anyway.
I use 1 of the Etrax just for a route run and the other one I use for when I am walking around detecting "as a log" and then at appropriate times download them to the Netbook and combine them with the PDA log to complete the trip.
The PDA only has a 2GB SD "old" and I managed to get an 800MB Natmaps of OZ "my paid version is 2.94GB", I have been using OziExplorer since early 3.xx.xx and the PDA has been using CE since Ver 1.1 Beta.
I also have managed to work out and Calibrate the WA Mining Tenement Maps to run under Ozi and get them on my PDA.
To end this little chat don't come over and steal my Gold seems I see foot prints of the Eastern Staters and holes not filled in and no Gold for me. has been a very dry Gold hunt these last few years.
