Dynamic Prop Balancing in NorCal

I bought the DynaVib kit to track down a vibration in my second engine that wasn't there in the first one. Anyone within a couple hundred miles of KCCR that is interested in balancing their prop - PM me and we can hook up.

In a past life spectral analysis was part of my job. For now I'm just curious to see how it works and how much difference it makes.
