It's the ultimate navigational tool. eTrex Vista has enough map detail to help you get out of town, an electronic compass to keep you on course, and a barometric altimeter to record the details of your trek. The Vista is designed to provide precise GPS positioning using WAAS. It also boasts an internal memory of 24 MB (Vista) and comes with a PC cable to download maps for greater detail. The VistaCX comes with a PC/USB Interface cable and 64MB microSD card, has the option for expanable memory, and a port for the microSD card. That's a ton of utility in a unit weighing a mere 5.3 oz (VistaCX 5.6 oz)
