During the last couple of days, I have been at a school with my new V3i. In some areas the machine bounces all over the place like there are multiple targets all over. Sometimes it would give a solid read.. Then a trash signal. I decided to dig one such time and sure enough...there was what looked like an aluminum can that was hit by a lawnmower..about a half inch away was a clad dime. I had a feeling there was something good amongst the trash. However every time I tried to pinpoint the good target. The pinpoint would lead me right to the trashy can pieces. After taking out the pieces of aluminum. It sounded loud and clear on the dime, and was easy to pinpoint. My question is: Is this a situation where you would just have to clean everything up to find out what was in the area? Or is there a "trick" to pinpointing where you can surgically remove the desired target. I am using the stock D2 coil. Would using say the 5.3 or 6x10 coil help? Even when there is so many small pieces of trash?
