Ya know, bent nails have been an interesting "study" to me with the previous FBS detectors. I don't know if anyone else has encountered this, or if it is just me. But 95% of the time when I find a bent nail in the hole (where I suspect a coin is hiding) the nail has been recovered from what I call the 7:30 position. In other words, the nail is in the lower left hand quadrant of the hole. Never under the center of the coil. I've come to believe that sweeping across in that one direction, the nail gives me enough good information to believe it might be a coin. What I've found using the CTX 3030 is that the additional information provided by seeing "multiple targets under the coil", and running with Ferrous - Coin separation, the nail is clearly placed in the ferrous range of the Smartscreen. And, if you are running with a level of discrimination that rejects the range where the nail represents, the nail will not provide a positive audio response. The best part is, if there is a nail and a coin in the "same hole" both targets appear on the Smartscreen, and the coin will provide the proper audio response. There have been a very few isolated incidents where the nail was very large and was laying parallel to the direction of the sweep, with both targets very close together and the same depth, the audio response of the coin was partially blanked out. But even in those situations, both targets appear on the screen, notifying me to keep looking as there was something down there worth digging. HH Randy
