A bit of a strange question, however anyone know how often does the 4 wheel alignment machines such as a Hunter etc need calibrating?

Interesting. I had my car fully setup at Centre Gravity a couple of months back and when I took it for its MOT earlier this month I happened to mention it to the MOT bloke. Anyway, he was keen to see what settings CG had used so after the MOT he stuck my car on their own Hunter rig to see.
I actually had a photo of the CG Hunter print out on my phone and the measurements my MOT places rig was showing were completely different. So either their rig was out of alignment or there is a degree of tolerance between them.
:thumbs:
As Chris and Pete at CG only do this geometry/alignment and chassis tuning work, I'd guess their equipment is regularly audited for accuracy.

To have this the lift and data base done is going to be about £600 plus vat so I could see it getting skipped if things are tight. You can see that the calibration was close even after twelve months use. That said the equipment is well looked after as my lads know how fussy I am.
Matt Seabrook said:They use a theodolite to check the lift first to make sure it's still in spec and then put a test rig on using my targets fitted to it. The pc is then put in to a diagnostic mode and the readings are checked against the stored settings. If it's out the calibration is done in the software.
