SureTrac Encoder Motor
Technology is a new option for
QM-7 mid-wheel-drive power
chairs. SureTrac autocorrects
small deviations in driving
to create a more intuitive,
straighter ride with few input
corrections. SureTrac is ideal for
drivers using proportional or
specialty controls. The system
reacts to resistance at each
wheel and sends motor-appropriate
amperage to neutralize
the impact of different surfaces.
