GPS devices that track your activity

[ConfusedPixie]

I was wondering if anybody had a GPS device that tracks where you go and could recommend one? Nothing too fancy, I would need a very good battery life (18+ hours), doesn't need a map screen just needs to work out where I've been throughout my walks and preferably map it out on the computer or have a way for me to do that! I essentially want it to do what I can get my phone to do with runkeeper and similar devices, but for it to not be my phone

So the Garmin Fenix or the Suunto Ambit are the two wristbased models which are for walkers. I've no experience of either, DC Rainmaker will give you very detailed reviews if you google.

Or you can go for something like a Garmin eTrex, quite a bit cheaper but not in a watch form, normally take AA batteries so much bigger.
