of a multiple tone ID machine. It WILL take some getting used to but bear with it because once you have the tones down you can move right past the junk and dig only the good. As with any ID machine it can be faked out, pull-tabs sholwing up in exactly the same place as gold rings, etc, but that isn't due to defects in tha machine or it's processing, it has more to do with junk items giving the exact electromagnetic response as a "good" item.
For my own purposes, the FERROUS sounds work better. Ahuge percentage of low tones will be iron, while a respectable number of coins and other goodies will present high tones. The exception is gold rings and nickles, these will hit in the mid-tones, but are easily discernable from the low (presumably junk) iron.
With the EXPII you have 32 tones to deal with, on the White's MXT (and the DFX too maybe) you have 195 or so distinct tones to contend with from what I've seen posted on this and other forums (no direct experience myself so I can only go by what I've read). Now here's the rub, dual, triple, or quad tone folks (like yourself) will complain about too many tones on the EXPII, while those coming from the MXT camp will complain of too few!
Such is life. In my own mind there is limited utility for a huge number of tones, as any given object can have at least a slightly different response to the detector field. why have 16 different tones for a nickle in various conditions when 3 or 4 will cover a nickle on something like the EXPII? Going the other way, we'd all love to have a machine that knew EXACTLY what was down ther, but a certain amount of excitement would be lost.
I look at IDs like this: The EXPII tones help me work around junk targets and help me to decide if something is worth digging. This seems "fair" meaning the machine is still guessing for me, and I'm making the final decision. In the old days with BFO machines, if we heard ANY change (for the most part) we dug it hoping for the best. Step into the future for a second, exactly how much FUN would it be for a machine to tell your there is a 1967 penny one inch away from a 1972 quarter? For me, the guessing and "hope" factor is what makes detecting fun. If I knew EXACTLY what was in the ground before I dug it, where is the "romance" or "hope", or "treasure hunter" aspect?
In other words, the fun is in the unknown, and if there is too much detail, the romance, the challenge, the FUN is gone.
Learn the tones by presenting known objects to the coil and getting a feel for the sounds they make. Then work the fields, and make a note of what sounds those familiar items (and junk targets) make. Before long you'll be able to decide without even refering to the cursor (or digital) display whether or not a tone is worth further investigation.
Honestly, I thought the tones SUCKED at first but somewhere along the line it just "happened" and now I feel VERY confident while out hunting and frankly wonder what the heck was my problem letting a few tones bother me. Trust me, it will come and when it does you'll feel the same way.
