Typically when someone is looking for an OBD2 Scan Tool, the ‘Check Engine Light’ is on and they simply want to find out what is wrong and turn it off. The need brings up things like cost, reliability, and handheld or the usb to laptop unit? Through research they think that all scanners are the same. It is true that the handheld types are very similar as most are made for an American company, SPX Industries. However the USB type that connects to your laptop as are almost as varied in capability as there are people.
The variety of USB obd2 scanners at different prices is rather large. A very basic one can be had for £16. However, the more reliable and better engineered ones are more typically £30 to £100.
