thats funny i just got fscan2 one most important reason was that i was under the impression that it would tell you what was the symtom such as maybe a medical history or what type of parasite etc but i am very very disappointed i would like to know what i am zapping for in other words what is does is just zap for things without even telling me what for i could of just used regular zapper for that and a lot less money very disappointed i was told it was like oxci but on a lesser grade you know where it scans and tels you what you are zapping for it is an expensive joke
