as well as bullets, cartridge cases, complete cartridges, buttons [size=small](military or ornate civilian types)[/size], clothing fasteners, all manner of buckles and other clothing fasteners, and whatever else might be of interest in all the older sites I prefer to hunt.
I have a few detectors in my personal arsenal, and I acquire and use most of what comes out to evaluate it, in-the-field, and learn what other makes and models can and can't do. In the end, I often grab my MX5 w/6½" Concentric coil for a lot of quick work, but if limited to only one detector for serious hunting, regardless of it being Coin Hunting or Relic Hunting ... or coin hunting in relic-type conditions ... my #1 all purpose detector is the MXT All-Pro.
The MXT Pro or MXT All-Pro [size=small](the same detector without any circuitry changes made)[/size] is all I need [size=small](or anyone in my opinion)[/size] when outfitted with two or three search coils.
My favorite coils that are always along with me are the 6½" diameter Concentric [size=small](5.3 Eclipse)[/size], the new 9" Concentric 'spider' coil which I usually have mounted on my MXT All-Pro, and also in my back-pack detector bag [size=small](that I use to keep all my spare coils on their own lower rods)[/size] is the 12" Concentric. When I have a large, trash-free site to hunt and/or especially if searching for moderate to larger-size targets, the 12" coil can really get the job done. The other two, however, the 6½" & 9", are the primary use coils for almost all of the detecting I do.
Get an MXT Pro or MXT All-Pro, the 6½" and 9", and maybe the 12" if you feel it might work for your applications, and get into some serious Relic Hunting.
