I have the 747pro.
Whats the manufacturer ? iBlue or transystem ?
747proS, have the double of memory,
8 MiB memory (± 250.000 track points - depending on what is being logged)
The 747 only 4mb ?
I buy the 747pro for € 88.31 on June 30, 2010.
And days later, I see that comes a new updated version. New Version 2: Double the internal memory by doubling the recording capadidad points. The new model goes from 125,000 to 250,000 waypoints. :(
