Only used once no longer needed as new.
The Ancel AD310 scanner is a well-built device with a nice size LCD display (128 x 64 pixels) that has a white backlight and contrast adjustment. It is able to display the test results directly on the screen which makes it a very mobile all-in-one package. This is also true because it gets the power directly from the OBDII Data Link Connector in your vehicle, so there is no need for batteries or an external power supply.
