Bought this because I needed data to tune an older car to pass smog. It's simple and easy to use, and the case and probe are metal. It gets the job done, but it just has an analog gauge with 1% increments for CO, so you'll be estimating for anything in between. Good enough for the purpose, though.

Necessary for Older more Analog types like ME. You can see the needle swing where you should be setting your Fuel Injection, or Carb. Not some Digital number that you cant see what is Ideal.
