ctx vs atx vs dual field

[Tom_in_CA]

Hmmmmm... I seem to remember that Boardwalk dig! ....

Ha, and that wasn't even a very productive one. I probably exageratted here the "one coin after another" effect (although yes, barbers, wheaties, etc... were found). But the part about the fellow from San Jose driving back home to get his other machine, was true. As to whether he got back in time to share in any of the meager goods, I dunno. But at least he wasn't going to dig 100 nails. Doh!

The original question was about bottle caps and flip tops. Not necessarily iron or erosion.
So is there any advantage between an atx or dual field ? Will a ctx or atx have the ability to discriminate out caps or flips?

Sorry Steve, got a little off topic there.

No problem. I enjoy hearing the stories too

"Flip tops" ? (pull-tabs): No. No advantage either way. They'll probably each get them to the same depth. Although a pulse will have an advantage in mineralized sand, getting them and their close-kin gold rings. But barring nasty minerals, the CTX can go about a foot (if you've got the big coil) on flip tops, as can the ATX. There may be minor disputes on this, but suffice it to say, they're close in depth.

But as for the "bottle caps" question: I would lean towards the CTX having the much better ability to discern them. It would depend on how corroded they are. If they're fresh, then they have a tin/zinc micro-coating on them, which fools some discriminators. However, there is tricks to this: they sound tell-tale different, when you apply different swing speeds. Whereas the pulse machines will have less tell-tale audio differences.

You'll dig plenty bottlecaps on the beach with a CTX. You can tell some. But some can stay a steady say 13 13 which is a U.S. nickel. Also the deep ones you need to investigate by digging down a bit. May be a broke ring, chain, etc. You just don't dig as many as a PI. ATX isn't gonna pick out items you should skip gold hunting on a beach. If it isn't a car or barbeque grill check it out. Not worth skipping.

I also have all 3.
I use the ctx 95% of the time. I got the ctx when they first
hit the market. IMHO theres no better beach machine for me.
I only bring out the other sticks to please my OCD

I found a old truck on a empty lot that had been buried two lots up the street from me. The owner told me it was there after I scratched in the ground for about a hour. He said his Dad buried it there about 20 years ago. He told me it was late 40's and I could have it if I would dig it up. I DIDN"T CALL HIM SIR when I said no thanks!
