The Tekonsha Prodigy is the latest and most intelligent brake control. This powerful control features new motion sensor technology. 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 and exclusive “Boost” feature that allows users to apply more initial trailer braking power. For backing into tough spots this is the only inertia control that works proportionally in reverse. A digital display depicts voltage delivery to the trailer during braking and displays continual diagnostics check.
