What is a Halda Twinmaster?
A Halda Twinmaster is a vintage precision, adjustable dual-display
mechanical odometer manufactured in Sweden. It attaches to your car by
way of a T-gear which drives both your speedometer and the Halda.
Twinmasters measure to the 1/100th of a mile and are used in
Time-Speed-Distance road rallies. Haldas are preferred for historic
rallying because they provide excellent precision while maintaining the
historic nature of the vehicle.
