Hey everyone I know there has been many posts about this issue and in my opinion I dont think its a real concern. How many times has our computers froze? What about our cell phones automatically resetting. It happens to me all of the time and I have an iPhone 4. I have noticed when my machine shuts down, it usually happens when I am swinging the coil and going over multiple targets simutaneously. Perhaps its an overload of the circuitry...who knows. I dont think there is an easy fix but I guess we will see soon. In the meantime I will just have to restart the CTX and Ill lose 11 seconds of detecting time. Oh well!!
