GC+device

Geocaching devices:
Although most smartphones can be used to geocache, most geocachers use actual GPS units to find the geocaches. Major names in the GPS industry include: Garmin TomTom Magellan Navigon Mio DeLorme Lowrance ...and many other brands.

Choosing the GPS for you can be subjective and depends on your price range and other factors.

My GPS of choice is the Garmin Legend HCx
