I've been using this Validator for 33+ years, and it is 36 years old or so, and we bought it with a PH9 motorized head, that we finally 'upgraded' to a PH10+ 3 eyars ago or so. We also have a PH1, but in all my years, I've only used it on 1 job, when I made the bridge operate like an ARM. I had EVERY extension on it, 50mm, 100mm, 200mm, an 80mm long extension-type knuckle, the TP2, then had about 100mm of probe on that, all so I could check some things on a car door fixture, with the fixture sitting on blocks, and extending off both sides of the machine. I had to sit under the bridge to see and get to what I had to check on it.
