Dusty, I'll tell you as nicely as I can put it.
Here is the rundown about VLF detector use in soil west of the Rockie Mountains, if you live there: I'm excluding PI's, because that's a whole different story.
(Most) Garrett metal detectors have trouble with our soil in Oregon, Washington, and N. California, and to some degree Arizona, Idaho, and Nevada too. NJ had some really bad soil too, as does some soil in the deep south. High Fe soil really cuts down on some detecter's performance, including the Ace 100, 150, 250, 350, and 1000-2500 series too. They are designed for Eastern USA and European milder soil, by using high gain. Unless you buy a high-end Garrett you will run into performance/depth problems in bad soil. As soon as you can, get a Fisher CZ, F-70, or Teknetics T-2 or G2, or Gold Bug Pro, you will be smiling a lot more. Whites do well in nasty soil too, but usually not Garretts, Minelabs, or Nautilus. (Cheaper) Tesoros do fairly well almost anywhere, but high end ones do suffer a bit for depth and cherry-picking in high Fe. The real old Garrett Deepseekers with extremely low op. freqs. did VERY well, but high-mineralization soil really requires something down into the 3Khz to 7 Khz to handle this soil well enough.
I would look for a trade for a different detector because the Aces are mostly designed for beginners, and they run into problems if the soil has too much iron in it. Many people don't need as much of a detector to search their soil. For example, Ohio has soil with roughly 1/2 to 1/4 as much mineralization (magnetite, hematite, other Fe) as Oregon or Washington State. Look for an old CZ, they do VERY well in the bad stuff, better than most, and that's why they are 1 of 2 preferred detectors for searching salt/high iron beaches. The other of the 2 is the Minelab Sovereign. Old Compasses and most Whites handle bad soil well too.
Please understand that I am not putting down your detector, just trying to help you in this hobby, and I want you to be as successful as you can get.
