Tabdog,I think you're right on using the disc. for iding targets. Check with Tesoro and you'll find that in the turned on mode, the Compadre is in all metal. The reason I'm sure, I got an SSumax a year or so after I got my Compadre and going down the hall in our house, the compadre would beep on the nails in the floor where the SSumax wouldn't. I called Tesoro as I thought possibly something was wrong with the SSumax and the explanation was that the SS had a bit of discrimination built in, to reject small iron (except in AM pinpoint) whereas when the Compadre is turned on it starts in all metal, then goes into disc. as you turn the knob up. I sold the Compadre as I picked up a second SSumax for the wife and by then had bought the Eldorado. Thinking back, I kind of wish I'd kept it even though I've picked up several other (brands) of detectors as well. Without a doubt, the Compadre is the best bang for the buck on inexpensive detectors. I've never tried one with the 5.75 coil, but the older, 7" coil model works great, and, hate to say it, but I suspect the majority of my finds over the years with other, more upscale detectors would have been found just as well with a Compadre. BTW the first year I had the first SS and still owned the Compadre, my wife and I were detecting an old logging camp where she got a strong signal using the Compadre. I went over and helped her dig. We hit an old lead car battery at better than 15". Granted that's a lot more mass than coins or gold chains, but I was impressed. Both machines hit hard on it. Snowed here again today so no detecting for a while. I'll be glad when our spring finally settles in.
