The code signing key used for BT747 had to be upgraded to SHA-256.

All files have been resigned and republished.
You may need to launch:

You can now order a G-Log 760 GPS data logger including shipping in Europe and VAT included for 89.99€ in 2016 - this is valid for 1 logger from our stock. Devices are shipped from France, the delay depends on the destination and varies between 2 days and 7 days. You want to spend less money, the iBlue 747 A+ offer is no longer available.
The G-Log 760 is an industrial type logger which is waterresistant (IPX3) and supports free-fall drops up to 1.5 meters. It also has enough memory to record 250000 positions. For more information, seed the manufacturer's page .

I currently use a Holux M241, and the features I like most are
However, the memory for 131000 track points (less with newer firmware) is a bit tiny for any holiday of more than a week.
I found the "Locosys GPS Walker" with about 2 GBytes of Memory (and a built-in mp3-player, who needs that?), but that thing has some disadvantages:
