I just got the new Excalibur ll and I need a little help. I used it for the fisrt time today and it didn't go well. Every time I got a target I would dig and not find a thing. So I guess my qustion is where is the point on the coil the target is under? I think once I find that out I well be ok. This is my first minelabs detector so any help would be great. Thanks Jeff
