I've read all I can find (here at least) and really did not find any actual opinions about the overall performance of the SOX2 for CA other than the usual "mines better, bigger etc, yours sucks". I would like a less cumbersome instrument for quick checks and the company (Field) propaganda seems inviting but how about honest real world use? I know it's a cheaper tester and as such you normally do get what you pay for. If YOU are actually using one on a regular basis, what are YOUR thoughts?
