Garmin CSx76 Goes Nuts Near Cache Site in GPS technology and devices Posted March 20, 2010 Sorry if this has been posted before, but my searching did not turn up much. Background: My cache team has just returned to searching after a two-year hiatus and my trusty 76CSx is proving to be the least effective of all of our cache seeking tools. I am heartbroken because me and this "big guy" found many caches when lesser GPSr's failed under tree cover, clouds, power lines, etc. Current Situation: For miles, the 76 seems dead-on until we get to within 50 yards or less of a cache, then the compass needle goes crazy. We've only cached one Spring weekend so far, but the nine we found, were eventually only found because we had a Geomate Jr and GC Navigator near GZ. I was sure that I needed to do something with the Garmin so I updated software, installed even newer batteries, callibrated several times, turned off and on WAAS and retested, but no luck. Anyone else encountered this with their 60CSx or 76CSx?
