Hi - I'm very new to Geocaching - just signed up today - but I've heard all about it from a friend.
I need some advice on what GPS unit to buy.
Buying the actual unit seems straightforward enough (depending on budget) but I'm also considering buying a satnav system at the moment for driving directions in the car.
Is it possible to get a system that will do both jobs, or is it better to get a separate handheld unit for Geocaching outdoors and a different one for use in the car?

Any advice would be appreciated.
