The MXT discrimination and sensitivity is such that many bottle caps (the crimped steel ones) will ID as a good quarter or dime signal, depending on how rusty they are, when your coil sweeps are centered over them.
The XLT and DFX, with their Signagraph capability, have an easier time of it. The Signagraph will show the target with multiple separated bars and give the bottle cap away.
When I am hunting with my MXT in an area where these bottle caps are plentiful, the easiest way to identify them, rather than digging them, is to take another pass over them in discriminate mode, but this time do it with the edge of the coil, instead of the coil centered on the target. "Rimming" the target this way will let the detector show them up as ferrous targets. This technique will work with just about any VLF detector.
Try it!
