[talk-au] Cheap data logger

[Delta Foxtrot]

I'm wondering if anyone knows of any cheap GPS data loggers that I can lend out to people, I'm thinking postal delivery workers here, that in and off itself it won't be worth stealing, something without a screen.

I'm sure there are other situations this could be useful as well, but it would most likely need a battery that will last 6 hours or a cig socket plug maybe a suction cup to get a half decent reception in a car.

Does anyone know of something like this?
