I've complained about this problem before but I spent the afternoon yesterday and part of the morning today calling Garmin trying to figure out why the pointer on my 62s jumps around. On average, as I'm walking to a cache it jumps back and fourth by about 45 degrees. I've now made six calls to Garmin and tried one chat about this.
Of of these 7 people only one has ever geocached and I don't think the others have ever used a handheld GPSr to go to a location.
Each tech makes changes and asks me to do a test. Which requires I hang up, go outside in 95 heat and a broiling sun and do testing, then call back. I've been through this kind of maddening cycle before, so with each tech I ask, "Now, after I do your test will we know the answer and there will be no more tests?" They each assure me it will. When I call back I get a different tech with different good ideas for things to try that require I hang up and round-and-round it goes. Other than the one cacher, they try to imagine what I'm describing and then dream up reasons it could be happening. In the chat I thought I would never get the guy to look at the video I'm posting below. But, even then he had new ideas and wanted to run me up the flagpole some-more. I finally gave up with him a canceled the chat.
I've tried twice unsuccessfully to speak to a manager. "None are in the area now." and "My manager's on the phone but I'll leave him a note and he'll call you back. Not so far.
