Perfect for adding to a key ring, always there when you need it. Charge it up in your car or at home. No need to take it off the key ring in the car, and when walking it can stay with your keys in your pocket, briefcase, handbag, rucksack or anywhere else you want and still maintain an accurate lock with the GPS satellites. Ideal for connecting wirelessly to your notebook, PDA or Mobile Phone by state of the art Bluetooth technology.
