THE USE OF WATCHES AND ELECTRONICS
Only mechanic watches/stopwatches/wristwatches with analogy displays are allowed.
This means: watches/stopwatches/wristwatches with digital displays are forbidden.
Also forbidden are all the well known countdown stopwatches. Forbidden as well are
radio-controlled watches, even if they have analogy displays.
DISTANCE MEASURING DEVICES
Only pure mechanical devices are allowed.
Not allowed are electro-mechanical devices, where sensors gives impulses.
Forbidden are electronical devices with LED- or LCD- displays.
Under prohibition fall also electronical devices, which can be programmed
and which can operate independently without connection to the car.
Forbidden are such devices, where the display gets the input from electronical
sensors that are installed on wheels, shafts, gearboxes or differentials. Forbidden
are also bicycle computers with magnetic sensors.
Forbidden are electronic averagespeed devices like Typ SW-01 and Laptops, Palms,
Communicators, GPS and navigation-displays based on GPS.
Permitted are the following mechanical distance measuring divices:
by way of exception allowed: Retrotrip
At the technical inspection we will check the full length of the speedometer
cable for impulse sensors that are not allowed, therefore it has to be checkable on
the whole length. Exposed cables and wires whose purpose can not to be proven will
be sealed and shut down.
Modifications made after the technical inspection that are against this regulations
