This is the basic Turbo Timer. The 'run-down' time can be set to one of 15 pre-set periods from 0 to 9.99 minutes. An audible 'beep' can be activated to register the count down period.
It also has a re-settable engine running time counter, to allow you to closely monitor the running time of your engine. (A more accurate record than simple mileage measurement). The Turbo Timer can also be used to display car battery voltage.
