Summary: The BT-Q1000 does what it claims: it will track your movements very accurately, as well as record places of interest at the press of a button and map them on Google Earth. It can also be used for navigation when paired with a PDA or notebook computer and GPS software. However, its software interface will confuse the uninitiated.
Pros: Can record places of interest at the press of a button, can log travel routes and easily upload them to Google Earth
Cons: The software might be a little hard to use for the uninitiated
