For DIYers who want pro-style data, look at the BlueDriver Bluetooth Pro OBDII Scan Tool, typically $100–$120. Its standout is phone-based scanner with repair reports and no subscription, and our verdict is Buy. The FOXWELL NT301 OBD2 Scanner usually sells for $50–$70.

Every pick has trade-offs, so we also tell you who should pass. Skip the BlueDriver Bluetooth Pro OBDII Scan Tool if you want a standalone handheld with its own screen. Skip the FOXWELL NT301 OBD2 Scanner if you need ABS, airbag or transmission codes.
