 It seems that the problem is caused by data corruption during the
 download. This has been confirmed by doing multiple successive downloads
 from the same device, and comparing the memory dumps. Some data packets
 are not identical, and those packets are located in the dives that fail to
 parse correctly.

 The Icon HD protocol doesn't use checksums, so we can't detect corrupt
 packets and unfortunately there is nothing we can do about that.
