It was my understanding that Nokta mentioned a while ago that the NOKTA IMPACT would be a unit built for Kellyco only, as a more or less exact copy of the original Racer, only on an ergonomic shaft as opposed to the terrible Racer shafts. As far as performance on the Goldfields go, both the CoRe, Fors Gold and Racer are left wanting badly. The Gold Racer I haven't used yet but will very soon, and even with it's new 'intelligent vsat, I don't hold much hope for it due to such a high frequency,
