A:AnswerHi Eric,
Yes, you can use the device for geocaching. It does have a new feature on the Rino 750 series called Geocaching Live. Below is a article on how that feature works.

A:AnswerHello,
This device is preloaded with worldwide basemap. That map includes major highways and cites but doesn't include TOPO or city street information. Also since the device will be used in Canada might be aware of about Rino's being used outside of United States. Article below examples that information.
