The i1d3 colorimeter is faster than the ColorMunki spectro, and likely to be more consistent when reading dark patches. On the other hand, it needs a suitable .ccss or matrix calibration to be accurate on a display. One of the manufacturer supplied .edr/.ccss calibrations may be good enough for your particular display, but if not, then you need a spectrometer like the Colormunki Photo or i1Pro to create the colorimeter calibration. Summary - they complement each other. Graeme Gill.
