Hello Chris,
The exact reason is because I'm hunting an area where every silver we find is at about 2", Between me and my hunting partner who uses an M6, we've pulled out at least 10 silvers from that depth, with the exception of one quarter at 4". With that said, I can easily see how I could miss surface targets if I have the Explorer trying to read down past 6 or more inches. I'd like to have a minimal of intereference from other targets it doesn't need to look at to get to this shallow silver. I also have an ACE 250, but I trust the XS more now. I think you guys might understand what I am trying to do.......basically, I want to keep the detector from picking up deeper trash as I try to pick out shallow coins. It simply does not need to look too deep, and looking too deep is a negative because those deep signals good or bad will mix things up. After that I will of course start trying to get deeper, but I don't like to dig shallow and deep at the same time. I like to pick at the shallow stuff, and when I feel all the shallow is gone, that is where I start to look deeper. I'll even remove some of the junk at this point.
