I am looking to calibrate my Pioneer PRO_FHD1 and I found two names Chuck Williams and Bob Jones...I saw a post where Chuck was highly recommended. Any comment would be appreciated.

Chuck is as good as it gets. Not only is he thoroughly qualified and experienced as a calibrator, he also is a long-time repair technician.

I also highly recommend Chuck. He use to live in D.C. Luckily he comes back East each Spring. He calibrated my Pioneer RPTV back in 2002 and I have him touch it up every 2 years.

Thanks to all who chimed in with their recommendation. I had Chuck over last week to calibrate my system and I am very happy with the progress. The Elite's color spectrum after calibration was almost on the dot for all 6 points on the ISF chart, I was quite impressed with its calibration capability.
