Have been looking OBD code reader but there are so many I don't know which one to get. Less than $300 but more would be ok.
What are you trying to do with it? OBD is a car and light truck standard, there is no standard for trucks and equipment.
My pickups and a jeep, we have computers for equipment.
I have an older OTC (2006) works well . If you want trans,srs ,abs your going to spend a lot more then. $300

It does not do much for bi derection testes but it’s a good code reader
I got the latest unit from harbor freight. I’m really surprised how good it is and all it does. 250.00 With coupon. It’s a great tool. It has lots of OE test functionality as well. I’d recommend it
