Ecco GPS Keychain

If you can never remember where you parked your car then the Ecco GPS keychain can help you find your way back.

Simply press the Lock button and it'll store the satnav co-ordinates of your current location in one of three memory spots. When you want to go back, hit the Return button and follow the compass style arrow to guide you to your destination.

It's accurate to around 10m and when you get within 30m of the destination it'll flash so you know you're close. There's also a red light to let you know if you're travelling in the wrong direction too.

The Ecco GPS Keychain is available to pre-order now for £69.95 from Firebox.
