I have been geocaching for half an year now, and am interested in a dedicated GPS for my birthday. I am currently using an iPhone 3G , and would like to get something within by budget. The unit does have to be somewhat rugged and hopefully waterproof, but does not need to have a touchscreen. A colour screen does help but is not mandatory, and it has to be powered by AA batteries, as rechargeables don't work for my long hikes. Any suggestions?
My friend is using the Magellan eXplorist 310, and it looks tempting.
