godigit -- this is NOT "from the horse's mouth," instead it's what I THINK is true, but not sure, so I don't want this to be taken as gospel. But, having said that, I THINK version 1 G2 software is the same thing as version 4 Gold Bug Pro software. Reason being, there WAS no "G2" initially; the Gold Bug had software version 1 (prototype?), and 2, and 2.9, and 3, and then 4 -- with version 4 being the "finalized" Gold Bug Pro version. At that point, the G2 was also introduced, and thus they called the "finalized" version 4 GB Pro software, when installed into a G2, version 1 G2 software. Perhaps there were some G2s where the software version showed up as version 4 -- which I would presume was version 4 Gold Bug Pro software which was for some reason (mistake?) not "re-named" version 1 G2 software. Bottom line here is, G2 software, and the "final version" Gold Bug Pro sofware, are the SAME SOFTWARE.
Again, don't take this as gospel, but I THINK this is true.
