I am thinking about buying this coil and need some input on it. I have a park that I know has been hunted before, in some areas it is heavy trash so bad that you get targets no matter where I move my stock coil. The vdi and graph is all over the screen. I know dig them all, but the area would look like a plowed field, dont want to do that in a park. This place has had a yearly picnic with a carnavile for at least 60 years that I remember. I hunted there yesterday and found nothing but tab tops in the not so trashy areas, so I know its been cherry picked rather well. Im thinking there may be silver in the trashy areas and these are by the food and drink stands. I need some advice on V3i settings and if the 4x6 coil would help.
