Bottle caps and small iron items

[8720roger]

Can anyone tell me how well the atx discriminates bottle caps and small iron objects thanks

bottle caps = not at all - usually a high low tone - same as gold for me.....iron = pretty well, usually a low high, rough sounding, and can use "iron check" on them to confirm.

Long, thin iron pieces like nails give a double bleep

Where do you plan to use the ATX and what are you searching for? If you are searching beaches or wading in shallow water, then I would recommend that you dig everything. Here I always use zero discrimination, the factory default setting. I dig a lot of hair pins, small nails, wire, pull tabs, and bottle caps but almost every hunt produces some gold or silver. I've often thought that the signal under my coil was just another hair pin only to find that a small gold ring appeared in my scoop. Now if you are searching for big items, you might want to eliminate all surface trash and in this case you could use the discrimination control feature. As you increase the discrimination, large iron is the last to be discriminated. On several occasions I've successfully used the ATX with the 15"x20" coil to find underground fuel tanks and pipes that other detectors could not find. I think this would be a great relic detector but I'll leave that for someone else to comment.

some of the new bottle cap are very hard to tune out even with a VLF detector . I set my disc. at 3. it gets rid of a lot of small iron.
