Steve, I've read this write-up of yours a few weeks ago. Thanx for writing it up. I'm on the coast of CA, about, about 7 hrs. west of you.
Ok, I know you say in your writeup the following:
"I am not trying to sell anyone on coin detecting with a PI. I repeat, I am not doing anything here but telling you what I am doing and my results. Those who want to scoff and tell me all about how that can't work in their parks etc etc please save it as I do not care. This is me doing for me what I want and I am liking it. Urban PI detecting is not for the faint of heart or those who detest digging junk"
I'd like to comment on that. First of all, I know you say explicatly you don't care what others think about your analysis of the ATX in parks/turf. So if so, this is also directed to Botics too then. But I can't help but comment: Your inference that those who detest digging junk in parks are "faint of heart" ..... has a bunch of inferences bundled up in it:
No one (especially a newbie reading a forum) wants to be called or lumped into a category of being "faint of heart". That explicatly infers that this particular type hunter is going to be "missing out" or "hunting wrong or unproductively" or "lazy" or whatever. And sheesk, which of us wants to wear a big "L" on our foreheads, when a noted authority like Steve Herschbach says they're ...... in effect ... a wussy for not wanting to dig junk ? On the one-hand Steve, yes: I agree that someone who ONLY digs "coin" signals, and NEVER digs a tab or a nail signal, ..... then yes, of course, we can both agree that this person is truly being TOO selective. However one of the tactics of turf, I'm sure we can both agree, is that ....... strip-mining is out-of-the-question, for most urban turfed parks. And as for jewelry: most guys who want to angle for jewelry are NOT wasting their time in blighted junky turfed parks ....... now are they? Hence the old parks are LOADED with low conductor shallow signals (foil, tabs, slaw, etc...) that hunters have been passing for 35+ yrs. now, in their religous quest for silver and high conductors.
It's not that we turf hunters DON'T want gold rings which are certainly there in the turf (at hundreds to one ratios ... or worse, in some blighted parks). And it's not that we DON'T want deep nickels (in fact, some hunters intentionally play the odds with machines like the CTX, to edit those *in*). However, let's face it Steve: There's a heck of a lot of parks that you would soon grow wearing of trying to be a hero and rescue rings and/or 15" deep nickels. Or you'd be kicked out of the park d/t too many holes.
If gold rings are a person's goal, then at some point they have to stop and ask themselves: "what am I doing in junky parks trying to dig all the aluminum out, in quest of a few gold rings hiding here?" If gold rings were REALLY their goal, then what-the-heck are they hunting junky urban blighted parks, ....... to begin with? . Their purpose would be better served to simply go to a swimming beach. Where a) jewelry losses are much more condusive, and b) digging in sand is much easier/faster.
When the TDI first came out (which is the not-too-distant cousin of the ATX, right?), a few of us here where I'm at, mused that FINALLY a pulse machine existed, which could possibly rival VLF for standard coin/relic/jewelry/land hunting. Because it's no secret that pulse machines usually afford more depth than VLF. However, it's also no secret that pulse machines didn't/couldn't reject iron, or have target ID, etc... But when the TDI came out, rumor circulated about how it could indeed be set up to identify/reject iron. And it could indeed be set up to tell high vs low conductors . Hmmmm.
So a few of us took a TDI out to a particular local school yard that dates to the early 1920s. At this particular school yard, I could, at that time, still fairly reliably go out and find a few remaining deep wheaties (7" or more), etc.... And the turf wasn't that junky. So I figured this would be a good place to test this TDI on flagged signals. I flagged a few suspected conductors: a) deep high conductors which were possible penny/dime type targets-at-depth. b) random clad, foil, tab signals c) iron signals. These were all fairly easy to "call" with my explorer, since I'm very familiar with it, and since it affords good TID for this type hunting.
Then we got the TDI out. I had studied all the material at-the-time written about it. Gone through the instruction book for hours. Studied everything on line from those early users about how to tell high vs low, iron vs conductive, etc.... And we passed it over all our marked signals with a variety of settings, over the un-dug flagged items.
My conclusion was that if a person elected to set up his TDI to identify iron, (the off-de-tuning, of ... essentially ... being out of ground balance), that he sacrificed depth. So much so, that by the time you had it set to properly identify a nearby flagged nail, and then went back over the 7" or 8" deep penny/dime signal, it was all you could do to get the penny/dime signal. Contrast to if you had it "wide-open" (in usual pulse power-house beach/nugget type hunting modes), then you would get the penny/dime signal to perhaps a foot or more, with room to spare. But the moment we tried to discern highs versus lows, iron vs non-iron, it was as if we'd lost all that "fabled depth" that pulses are famous for. So in effect, it was like "why change then? Why even switch?"
So I determined then and there that a machine like the TDI was just way-too-squirelly sensitive to be used for typical relic/land/turf type hunting . Ie.: the "apples to oranges" others here are saying. For the beach and or nuggets, sure. But no, not for parks, schools, relics, etc...
And yes I know the ATX is improved over the TDI. But "improved" can be a double-sided sword. Because if by "improved" that means MORE sensitive, then often-time having a machine that is even MORE squirelly senstive is NOT the type machine you want to be using in a junky park. But if by "improved" it means a better ability telling iron vs non-iron, or highs verses lows, then yes, that would be an improvement if someone intended to use it on land.
However, correct me if I'm wrong, but the consensus on the ATX seems to be that any iron check feature it has, is only good to the top 4 or 5" down. Beyond that, and you can kiss iron ID goodbye. Right? So then, for purposes of land/park/turf usage, if this is true, then I don't see the ATX as any more of a land machine, than it's evolutionary predecesssor: the TDI.
As far as your park being 50/50 nails or junk to coins, then either a) you have extremely clean parks, or b) you have the ATX set up in some way to reject iron (but simply got fooled by the assortment of nails shown in your link pix?), c) and/or perhaps were rejecting low conductor signals, if the ATX offers that option?
But in the parks I can think of, where we routinely pull old silver coins out of, you would do a lot worse than "50/50" ratio of junk to keeper coins, if you went in with a dig-all mindset.
steve, have you ever read this post of mine? http://www.treasurenet.com/forums/general-discussion/373782-true-story-dig-all-lest-you-miss-gold-ring-philosophy.html
