I have an garmin eTrek (very basic unit). My familly and I have used it to find a few geocaches, but we have not been able to figure out how to load maps. Consequently, we've always used a combination of the GPS and a paper map. (works ok)
NOW I have committed to teaching my girl scout troop all about geocaching, and my biggest question is, with the smartphone apps and ipad apps, is there any reason to buy a handheld hiking GPS, if you have a smartphone (yes most f the girl scouts have their own)? do the Smartphone apps use the same satellites? Would we have to have "cell phone reception to use the smartphone for geocaching?
Would the smartphone have all the access to the same maps you can use with the handheld GPS units ?
(I don't have a smartphone yet -- I managed to use the iPad in my neighborhood to find a cache and it worked ok.)
