The Snap-on MODIS Edge and Diagnostic Thermal Imager Combo Pack is designed to give technicians the tools they need to get jobs done faster. The MODIS Edge is a full-function scan tool and scope/graphing meter that can read an error code and help find the initial diagnosis. The Digital Thermal Imager then uses infrared technology to make heat "visible" and reveal problems anywhere on a vehicle. Technicians can see hot and cold area of the vehicle components to identify both functioning and non-functioning components more easily.
