Since it's coming from makers of the Spooky2 unit, I'm going to venture it will follow similar production methods as it's predecessor. To which I'd add, has proven surprisingly accurate on the bench in spite of it's fabrication costs and origins (China).
That said, my source claims that these units will have improved frequency control measures in the upper registers(Mhz) that place the unit in unprecedented performance categories. Though I'm really not sure what advantages this would bring given that most users sweep or wobble their program across frequency ranges. Which brings us back to bragging rights less any real world validation or verification.
