Peterson 490ST Strobe tuner....good?

[SUSAN P SWEARINGEN]

That's exactly point.  I understand you can do it manually, but why?  Why
would you want to take the time to do it manually in the customer's home
when there are devices on the market that do it automatically?

I think the $800 price difference between the Vertiner and the 490ST is
significant but still, your paying $600 and having to do manual
calculations.  I just don't see the benefit of the 490ST, except as a
training tool for new technicians.
