Well maybe that is a bit of an exaggeration but my experience over the last 5-6 weeks have got me thinking about the D2 in a whole new way. It started with trying Sensitive Full Tones at a few worn out sites and being surprised to dig a half dozen or so buttons and other nonferrous at each of those sites. I wasn’t sure if it was the -6.4 Disc or the Full Tones that was unlocking these targets from these tired sites. A detectorist on another forum suggested I try General with its unique Conductive Soil Subtraction but use it in Full Tones. I used it last Sunday and this Sunday at 2 more worn out sites and I can say is that it brought them both back to life with each giving up a dozen or so nonferrous targets in just a few hours of hunting. Most of these targets were iron masked to various degrees, but the Full Tones Audio excels at alerting you to there being a good target mixed in with the iron. When a mid-conducting tone broke through, it was money in the bank that there was a nonferrous target there.

As I mentioned in my Sensitive FT review, the iron falsing is annoying. I think it is exacerbated when using Full Tones. That’s just a bug with the D2 that they hopefully will work out soon. After a while my brain just listened for the mid conducting tones. Not a good strategy if there is a decent chance there could be iron masked high conductors at your site. I hardly dug any iron when I investigated some of those high tones because I either swung around the target to get a positive iron ID or I toggled to the adjacent Sensitive Full Tones that falses just as much as General but it’s easier to hear the iron.

Most of the time I hunted with Reactivity at 1.5 but bumped it up to 2.5 in the thick iron. I actually pulled a small cuff button using R=4 in an extremely thick carpet of iron.
The 9 buttons a pulled today were all small except one. Some were surprisingly deep. Twice I thought I got called out by iron but when I rescanned the hole, the mid conductor was still in there.

For the type of hunting I do, I believe Full Tones is where it is at. The audio is very informative in PWM. Square may sound nice to you old Minelab users, but PWM is much more descriptive to my ears. Combine Full Tones with General and its frequency subtraction mode, it has a ton of potential.
