Portable unit for insertion into the OBD II connector. It is able to read the fuel and odometer status from the connector. This allows it to keep a logbook including this information.
Use the unit in any case where a fixed installation would be undesirable. Example situations: short-term operative leasing vehicles, third-party vehicles temporarily assisting your fleet, replacement vehicles when your vehicles are being serviced. Can also be used to outfit your fleet with GPS units without needing a standard fixed installation.
