Hi Jose,
The JetJoe electronic balancer is fine for the home miniature turbine builder, however, for serious service work and commercial balancing I feel it's accuracy isn't up to the standard required.

Don't get me wrong, the JJ balancer works fine, I find I can get down to very small dual plane increments with the "Schenck" machine I have access to..... whereas the JetJoe balancer has only a single plane system. Here's a pic or two of my Schenck machine.





Hope this helps,

Cheers,
Smithy.
