Well just used this for getting my 500 dead on, and set level in my brain software,
Before when I have done this using my phone I was getting a bit of movement when I then put it into self level mode, even on the bench, this time no movement, WOW is all I can say,
It took me about half an hour to true the main shaft and level the swash, as it was the first time I tried it, next time I will do a write up with some pics,
