Because you can never have precise enough location data when traipsing around the woods with the fam, Garmin has upgraded its Rino 520 and 530 GPS receivers / two-way radios with the highly-accurate SiRFStar III chip: meet the 520HCx and 530HCx. Like their predecessors, both models feature a 14-mile range (in an open field, we assume), built in basemap of the Americas, FRS and GMRS capability for chatting or transmitting coordinates between devices, and the rather impressive ability to hang out one meter underwater for up to 30 minutes without any ill effects. You also get a miniSD slot for loading additional urban and topographical maps, and if you step up to the 530HCx, a seven-channel weather receiver, electronic compass, and barometric altimeter. Look for these units to hit stores sometime next month, with $450 and $500 pricetags -- both of which are lower than the initial MSRPs of the earlier, less-precise Rinos.
