Looking for new portable CMM

I can only say from my own experience I've tested it out on a part that was roughly 25" long in the features I checked. I don't want to start the old Gage R&R on a CMM discussion, but I reran the same part 15 times without moving it and my total variation in any given measurement was .043mm. This was on the arm I spoke of that is not (IMHO) properly utilized. Obviously I avoid the springy part of the steel table, but my probe calibrated at .040mm, and I was using a 6mm probe (which as I stated above I don't like for the flex). I had to use the 6mm for the part I had, and I had to do it quickly because it was an unsanctioned test that I needed to perform so I knew what I was getting off that setup. I had known values on the part I checked from my Cordax RS-150, and those values were within the range of the .043mm (not necessarily the average of the range). Lastly, I tried to measure every hole with the probe coming in at the same angle each time and the same spots in the holes. That's the best I can tell you.
I am going back up to that facility in a couple days. I'm bringing a tooling ball with me that I've measured on my Cordax. I want to see if I can improve my results using that.

The accuracy of that 5000 series can definately be better, and I gotta think that with a better arm and a better calibration method I could bring the range of measurements to within a +/-.0006" window. Please noone berate me on my methods here, I was in a hurry and trying to work under the radar. I don't have a lot of support in my strive for excellence at this place.
