The Signaloc-Pro and the SatHawk 3000 meter come from the same factory. The user instructions are pretty much the same: http://sathawk.tv/Instructions.htm
As far as the datafiles are concernered there are no guarantee the datafile flashes will work. The two meters may have different processor chip lots, making the satloader and sat files incompatible.
If you use the SatHawk 3000 data files, you are doing it at your own risk.
