I spy with my GPS

NEED to know just where your tractors or trucks are at any one time? The EB7 is a miniature satellite transceiver and global positioner – small enough to be concealed on the roof of a cab – which automatically transmits its position when the vehicle moves. It can also warn if any unauthorised movement is taking place. Marketed by Cambs-based MSC International, the EB7 costs about £2500.
