We always carry at least one compass along with our garmin map60cs. Even though this is a top shelf gpsr, with built in compass that is is supposed to be accurate even when stationary, that is not the case. The gps compass page or the map page will tell me which direction to head, I need the compass to know which way is which (say that 6 times fast). My silva compass came with its own instruction pamphlet which is quite adequate to get you started using a compass. And yes, always carrying extra batteries for your gpsr, and if you dont have mapd loaded into your gpsr, carry one along also.
