I have a USglobalsat BT-335 which is a fantastic GPS data logger but their Mac software is pretty buggy. The worst bug is that once the amount of logged data is over a certain size, the software will just stop downloading. If it weren't for LoadMyTracks, the only option I would have is to locate some PC running Windows so I could access my data. Fortunately, I can just pick the Globalsat DG-100 which works with the BT-335 as well and use LoadMyTracks to download the data.

LoadMyTracks also allows me to view elevation profiles generated with my BT-335. The Global Sync 2 software for the Mac has a bug where if the elevation goes below 0 it will output an elevation of 429400 plus meter readings. If I load the same data using LoadMyTracks, it correctly records the elevation as below sea level.
