As mentioned elsewhere, I have this little obsession with capturing data about my activities as I move through the day. Cheap, large scale storage makes it easier and easier to capture and archive such data, so why not?
Several months ago I added the i-Blue 747 GPS Logger to my collection of gadgets. It pretty much does what the title suggests — it records its GPS position to internal flash memory. Periodically, then, I download the GPS data file as a CSV file. That’s about it. Apparently it has Bluetooth so you could sync it wirelessly to your laptop or smartphone if you wanted to do real time mapping/directions, but I’ve never tried that feature (and don’t plan to).
The main advantages of the i-Blue 747 are that a) its cheap – $65 on Amazon at the moment; b) it acquires GPS signals fairly accurately, even in less-than-ideal conditions; c) it is extremely small; and d) it lasts all day on a full battery charge.
I’ve had nothing but positive experiences with it over the past few months. I definitely got my $65 worth on this particular gadget.
