Any mechanic can easily use his Launch professional tool to gain bi-directional control of another Launch professional tool. If you have a problem vehicle, your (friend/technician/partner) can work on the vehicle with his tool from his shop. This application is very good for fleets with multiple locations. Certified technicians can analyze live data and perform special tests between any two locations with good Wi-Fi signals. There is no need to be “on site”. launchtechusa.com/ launchtechusa.com/tech-to-tech/
