CURT Mfg has introduced a brake controller for the modern age. The Echo is a portable, plug-and-play device that enables the driver’s smartphone to control and monitor all trailer brake activity through a dedicated app. The Echo plugs in between the 7-way connectors of the tow vehicle and trailer. The ‘Smart Control App’ monitors the trailer brake, delivers status updates and allows for manual control from the Bluetooth paired smartphone. The app can store multiple user and trailer profiles, making it a handy tool if you have multiple trailers. The echo is extremely portable and designed for long-lasting weather resistance.
