Rusty was not wrong in recommending the Vaquero. I bought mine from him and had a long talk with him about it before buying. All I know is that maybe there is something wrong with it or you just gotta keep usin it and getting the hang of it. Its a newer machine to you and time can help. That just doesn't sound right to me what's goin on. It really just depends where your putting the coil. If its there you should find it. I mean If you don't know exactly where the front yards of these houses were then you might be detecting right over where the foundations were which is leading to all the junk. You found some good stuff so far.. It'll get better
