I recently got a DFX. I am a retired LEO. My agency has reached out to help find a 9mm bullet in a criminal case. The bullet fell out of the suspects clothing as he ran from the scene. (so its not deep, if not laying in the grass). I will need to cover an approx 3,000 square foot area of a front yard. I already have the area gridded off. Im using an Eclipse DD coil to cover as much ground as possible but I also have a 5.3 coil if that would be better. The bullet has been laying on the ground a little less than a year and is believed to be jacketed but not sure. With that being said here is my questions.**which coil should i use.**What pre set program should i use?** What adjustment should I make since the target is so shallow?Thanks for any help.
