BCA has announced a limited number of their Tracker II beacon have an issue discovered by the Jackson Hole Patrol, but related to my hearing some random beeping from my early production beacon last winter. The beeping was a bit strange, but I attributed it to cold weather or low batteries, or something, and was not highly concerned as my unit was an early model. But apparently the beeping indicates behavior which can inadvertently change modes. Again, this is a limited number of units and a software update takes care of it. If you own a Tracker II you should get it worked out with BCA.
