Tekonsha Prodigy
With Prodigy, no manual level adjustment is necessary, it adjusts itself to varying terrains as you drive. It is equipped with a sensor that detects the tow vehicle's rate of deceleration, applies proportional braking to the trailer and features an exclusive Boost feature that gives users the ability to apply more initial trailer braking power. For backing into tough spots this is the only inertia control that works proportionally in reverse.
