Like this little GPS unit for small game hunting or finding the car

[uncle buck]

rather cheap and works great, small fits anywhere.  Notice they have yet another unit like this on this web site too.  Might be a bit more enhanced.  Anyway  nice item to own if you don't want to carry the bigger GPS unit that takes a holster and is more apt to be bounced around in bags and such..
