Selling my second GPS. It is a rather battle worn, low sensitivity unit. But it does float (being a marine unit) but is equally at home on land. If you're not going bush, or urban, and want a cheap unit, this is it. Also a good simple unit for boaties. Research <url=http://www.amazon.com/Garmin-GPSMap-76S-Waterproof-Hiking/dp/B00006662D]Amazon for more info[/url].
I can probably find a combined auto and serial cable to go with it. Can take maps, but only a limited subset as (from memory) it only has 24MB of memory within which the maps can fit.
Again, will go on TradeMe in 24 hours, but wanted to offer it here first. It would be a good cheap unit, and a good way to test the waters of geocaching and GPS without spending a lot of money. Looking at TradeMe, I could probably get a bit over $100, but through here I'd be happy for $100
Offers via PM, or email me rediguana at gmail.com. Again, Christchurch pickup only, no posting.
