Yeah he does use a i1pro2 but that shouldn't be used as a slight against his calibration and video knowledge in general, i have followed his reviews and he's quite good. What gear you own sometimes doesn't depend on just one factor, or being a professional. As a related example, the professional on this forum who does 4k blu ray disc reviews (ralph potts) uses a TCL LCD in his setup to evaluate 4k dolby vision discs. To me that doesn't make him a less of professional or untrustworthy of his assessment of the dolby vision picture quality.That's true, but it's also true that he only uses an i1Pro2 for his spectro, "proudly" featured in his videos(!), which is rather sub-optimal for a professional.
