The CURT BetterWeigh Mobile Towing Scale is a Bluetooth-enabled, smartphone-compatible, compact device that plugs into the vehicle's OBD-II and measures the real-time weight of the vehicle and trailer, cargo/payload, tongue weight, pin weight, weight distribution, and trailer brake gain. It then displays them on the users Apple or Android phone. BetterWeigh is powered by TowSense Technology, an accelerometer that measures changes in force and acceleration. The device works for bumper pull towing setups, gooseneck towing, and fifth wheel towing. It is also ideal when loading a vehicle with cargo, supplies, or equipment, giving users a live look at the vehicle's weight as cargo is added.
