I don't have experience with HF code readers so not sure what all they are capable of but if they are strictly a code reader then I would say they aren't really something I would buy unless you just want to throw parts at something and hope it fixes it. All a code reader can do is give you a code, guess it gives you a starting point but that's it. Now your at a dead end road as far as diagnosing the real issue. No clue what they cost but you can run to parts store and get the same done for free. Or buy a bluetooth obdii adapter for cheap and use your phone and most will do more then just read codes. Guess I don't see a market for strictly a code reader.
Unless you're a professional that works on many different platforms, a simple reader will be fine. Most codes are typical throughout all manufactures. The operative word in my statement is "professional" I've been in the business a long time and all I have is a $53 MATCO reader.

I'm with signcrafter. Ok so my reader tells me I have a P0300. Cool.
It doesn't tell me which cylinder though.
I guess with a lot of extra work I could start with #1 and just work down the line. Maybe I'll get lucky by the time I make it #8.
Or get a scan tool and monitor exactly which cylinder(s) have a misfire.
I had this happen and on another board people were saying just replace all the plugs and wires, replace all the coils..
Well turned out it was none of that. Turned out it was a bad injector on #8. I would have wasted a lot of time and money with just a reader.
Also the reader I have doesn't do anything for resetting things like the AC system actuators or make those things operate for testing either.
Heck I don't think it will even read those codes for a lot of that stuff.
It will read emissions stuff and let you know which code has set your CEL. But thats it.
And no I'm not a professional but I do all of my own mechanic work to my vehicles.
So I bought a bidirectional scan tool. Should have done it long ago and stopped all the guess work.
