[size=large]One key reason is that several of the other responses touched on my basic reply.
To be honest, I try not to respond to questions related to Tom Dankowski's article because ... well, let's just say 'because' and let that be it.
When I read this the first time a while back, just as when I read any one's article or a post on a forum, I try to eliminate the meaningless comments first such as:[/size] ("I recovered a 1952 silver dime, face down.") [size=large]It doesn't matter if it was face up or face down, it's the same target and has nothing to do with his story.
Once you eliminate all such statements in an article, then you have to take a look at the particulars of the experience they are trying to convey, and then pick it apart. Be analytical about what's being reported. I mean, I'm not the greatest write or the best at conveying my every message/thought, but that doesn't mean I can't pick things apart and questions it. For example, in the second paragraph I read:[/size]
At a local school in Titusville, Florida I detected a weak, yet consistently repeatable coin signal from my detector. Before recovering the target, I thought this very deep coin signal would be a perfect opportunity to test every possible control panel set-up configuration of the detector. My learning curve was complete, finally! No adjustments to the control settings improved the signal to any greater extent. I then recovered the target. I recovered a 1952 silver dime, face down. At less than 3" deep, I was absolutely stunned on how weak the signal was. I instantly (and incorrectly) lost confidence in the detectors abilities. I placed the dime back into the 3" deep hole and passed the standard 8" coil over the silver dime. The detector nearly gave me an overload signal. That's more like it, I thought! I then put the grass plug back into the hole, covering the dime. Now the signal nearly disappeared again. Confused, I removed the grass plug and passed it over the coil. No signal. The plug was clean. Disappointed, I pocketed the dime, covered the hole and moved on. Less then one minute later, I received another identically weak signal. At 9.5" I recovered a worn 1928 mercury dime. It was less then 4 feet away from the first dime in the same type of low mineral soil conditions. Wow! What is this inconsistency?
[size=large]He said he had about 200 hours on the Fisher CZ-6a and his knowledge and learning curve were virtually complete. Yet, he said he got a detected a weak, yet consistently repeatable coin signal and was surprised that the dime was only 3" deep. He didn't comment on what the Coin Depth reading was, and if he had a weak, deeper-sounding coin-like signal, it seems like he might have checked the coin-depth. No comment about that.
After about 200 hours of knowledge he instantly (and incorrectly) lost confidence in the detectors abilities which doesn't sound, to me, like a very savvy detectorist who has been master a detector. I would have immediately asked "why?"
Dankowski continues this same paragraph stating: Confused, I removed the grass plug and passed it over the coil. No signal. The plug was clean. Well, the knowledgeable detectorist, of the average hobbyists with a bit of field time, ought to know that you sometimes can, and sometimes can't get a signal on a coin you can see in an open hole, and that replacing the plug/dirt, you might be able to get a response. All makes and models are different and a lot depends upon the detector in question as well as the search coil and set-up.
But with these statements, he on;y said he passed the grass plug over the coil and, getting no signal, determined the plug was clean.
Well, if I had a weak signal on a shallow 3" silver dime, then I would question the plug and check it in an All Metal mode, but T.D. didn't state that. The suggestion would be that he checked it in the motion Disc. mode he was hunting in. Also, I didn't see what Disc. level he was using and if it was too high, that can also lend itself to some target masking issues.
Less than a minute late and only 4 ft. away, according to his story, he found a deep silver quarter. being that close, and only a minute away, he could have turned back to the plug where the dime came from and check it in All Metal since he apparently didn't the first time.
So, by the end of the fist lengthy paragraph I didn't know what it had to do with the topic of "getting technical" and, as I continued, I read statements that could be questioned:[/size]
In a professional test garden, [size=large].. What the heck is a "professional" test garden? A test garden is a test garden, and I'm not big on them anyway because they don't duplicate "real world" detecting encounters,[/size]
I buried a tiny staple (slightly rusted) from a standard household stapler.[size=large].. Who cares if it is "slightly rusted?" Besides, a rusted staple is more difficult to detect than one that is 'clean'. And, how did he come to pick a standard household staple in the first place? It's not like household staples are in high use and readily discarded in sites hobbyists generally frequent. Why not use a more common-size nail?[/size]
