Professional Scuba Inspectors (PSI)

[grains]

For the SCBA Techs out there: Has anybody taken the cylinder inspection classes by these guys?

What did you think of the instruction, and do you think that it has value with your cylinder inspection routine?

They also offer a class in Eddy Current inspections. Again, I am unfamiliar with this. Same questions as before.

Thanks for the help.
