As one of the first people to get the Pro Package you got one heck of a deal. Personally, I think Nokta "WAY" under priced this machine to begin with. I got to run an XP Deus and this machine costs 1/3 more and delivers 1/4 of the results. Deus is not close to the impact in any way! I come from an ATpro and Etrac. Etrac was difficult to get the machine stable and slow as heck in response time. It was like "Get Used To Delays" and "ENJOY". No detector on earth has found more great stuff than the ATP. PERIOD! it is the most bought and used detector out there. You just got an ATP on steroids and I cannot say enough about the Impact. The Killer is switching frequencies on the fly and the program ability of this machine, never mind, online updating. I was responsible for the addition of tones and tone notching in DI4 mode in the latest update. Nokta listens and responds in the most professional manor in "Listening" to it's users.
You made a wise choice. If I can assist you in any way, PM me.
