Automotive Scan Tool Reviews: Autoenginuity, Innova Carscan 31403, Bosch mobile scan 1050

I wanted to show 3 of my scan tools that i use in my auto repairs. The best one is Autoenginuity's laptop scan tool. Second best is Carscan OBD1 & 2 by Innova. And coming in at a close 3rd is the Bluetooth scan tool by Bosch which i purchased from Oreilly's auto.
