An OBD2 scanner reads fault codes through the car's diagnostic socket, while a battery tester shows state of charge and cranking current — Ancel covers both, including combined 2-in-1 models and a version with a built-in printer. Next to them sit an inspection camera and an FNIRSI oscilloscope. Check whether the scanner pairs with a phone over Bluetooth or works on its own screen, and whether it supports your car's make.
