Yeah, Mike, a 16' piece of PVC would be like a noodle even without weight on the end! I'm just offering a solution in theory....but you know what Yogi Berra said about theory. Now if the tape is moving, you should be able to pick a more convenient spot to measure, say 1' or 2' out the innermost point of travel of the tape. If it is moving, you should be able to detect movement at that point. Sounds to me like it is not moving though, sadly, if you are not seeing any change in resonance.

Obviously, you could have the control head near the search head, using the current cable, then extend the audio cable. Low impedance audio line can run 24' easy and then you would not have to worry about RLC of the long search coil cable interfering with operation. Plus you could use any old cheap 2 conductor wire.

Thanks for further comments @2valen! i searched numerous full text databases: 18th c British periodicals, 19th c US newspapers, three or four academic journal full text libraries, and nada on "Joy of One" or "Joy of 1," aside from various citations of the two instances I noted above. Don't have full library digital access anymore, only limited alumni access, but I can usually dredge up a few references on almost anything that way. Wine industry in NY started mid-1830s in a small way but got serious and grew tremendously beginning in the mid-1860s, even though NY State was a grape growing region before that. This is one of those artifacts that caught my eye. Strikes me as a very poetic phrase and intriguing item that speaks to me...now I'm just trying to figure out what it is trying to say!

C'mon 2Valen, spill the beans on the details on what you know, OM! That's what crowdsourcing is all about There seem to be Victorian era glass seals intended for sealing letters. My feeling is that the emergence of glass seals had to do with technological improvement and manufacturing economics rather than any particular practical advantage in glass, aside from colorful looks. I have seen impressed pottery and pipes, and even wine bottles (glob of glass with seal impressed on body), but never saw any original seals for this purpose. One reference I found speaks of brass or molded clay bottle seals. Glass would seem to be a sketchy material to use to stamp molten glass. I am not sure of the historical antiquity of wax seals on bottles, which is common even today (although the modern seals are probably all plastic.) This seems to be a poor mans version of the all glass sealed bottle, which stems back to at least the 17th c. and show up profusely in the archaeological record of the Colonies. Tanqueray gin has a red wax (plastic) seal on the front of the bottle, for example. A touch of class, eh? Here are some pics of glass seals from Colonial Virginia: https://mesda.org/exhibit/wine-bottle-seals/ Those are very prominent names in Early Virginia. Bottle seal database: https://www.cova-inc.org/wineseals/visual.php Another overview of the bottle seal: https://apps.jefpat.maryland.gov/diagnostic/SmallFinds/BottleSeals/index-bottleseals.html Some interesting artifact background stuff on that site, BTW. ---------- As for the "Joy of One" motto, I found two literary references using that term, one a stanza of Wordsworth, commenting on the post revolutionary esprit of Calais of the one year anniversary of the siege of the Bastille (1790) "How bright a face is worn when the joy of one / is joy for tens of millions" And an ancient folksong, collected in Connecticut but seemingly of old British origin, "The Joys of Mary"--usually framed as a Christmas Carol "The first joy that Mary had, it was the joy of one, To see her son Jesus in the world to come"

Yes, but ROY was a common spelling for the French Roi in that period also and that is one French word that most educated English speakers would have known. I am not sure that that is an "I" on the seal. Looks kind of FAT for an "I" or even "J." Closer inspection might help narrow this down. Does "Joy of I" make any more sense than "Roy of I?" Maybe it is a literary reference? Otherwise, it is a bit odd either way, I think. Perhaps the scene depicted might offer clues? As for glass being shown on that page, are they?...or are they agate, carnelian, and other stones? Glass would be molded, I believe, whereas stone would have had to have been carved and engraved in reverse bas relief. Most of the seals on the page supplied, especially earlier Georgian ones, do not appear to be transparent in the manner of paste glass. My thinking is that mass produced glass items would be later and cheaper than artisan-crafted earlier versions. If "mass produced" then the wording must have had some general currency beyond a weird one off. Who would buy it if it was weird and senseless? Are the glass seals French or English made? They were more common on that side of the Atlantic for sure. In 18th c America, I'd think a seal would be something that only rather wealthy folks would possess, whereas a democratization of the manufacture using molded glass would open up the market a bit. Anyway, this is all hopefully productive speculation on my part, as I am no expert on wax seals. I'm interested in that artifact though. Studying historical archaeology in graduate school, I developed a tendency to spin inferences and strings of questions to check out via further research, often based on little or no preliminary evidence! 😎 Gotta start somewhere!

If French manufacture, perhaps it is a code-mixed expression "Roy of I (or 1) from Roi for king. King of my own castle sorta expression. One man riding free. I venture this interpretation since the only glass seal on the page from Pimento has a Fleur d'Lis motif which put me in a French mode. 2Valen's point about seals on bottles of wine is a good point. Seems commonly done in 18th c. America.

Post a pic! Very interesting artifact you dug up there. Many of the Victorian wax seals are whimsical designs, but throughout history seals were used for important purposes, such as marks of identity and legal authority. A lot of the British/European seals have heraldic symbols on them, but there was a lot of "fun" stuff too, especially through the second half of the 19th c. Did you find this in the States? We don't really do heraldry here~~~ Once. when i was working in a used book store in Philly, a snooty old lady asked in an affected English accent if we had any books on heraldry, I answered, "Harold Ray? Never heard of him." 😜

That's obscure! Maybe a variant typography of "Joy of I" --which is still a bit of a puzzle. If you can find some sealing wax or even modeling clay, make an impression. Appears to be an interesting design with horses and whatnot. I think the technology goes back to Ancient Babylonia. I know I have seen Roman seals in an archaeological museum. If that one is made out of glass paste, i'm tending to think it is late 19th century...just a seat of the pants estimate. Perhaps a positive impression in wax or clay will offer up more clues.

Looks like a wax seal stamp What does it say?

Kac, Here's an extension cable for Tejon https://www.metaldetector.com/tesoro-4-pin-extender-cable\ https://www.seriousdetecting.com/product/tesoro-5-extension-cable-tesoro-delta-series-metal-detector/ Seems unlikely that they would use a custom connector....that sounds like an expensive option to pursue for no good reason. Also, Cors makes aftermarket coils so where are they getting their parts? Vintage US connector companies usually have the name molded into the plug somewhere. Some old radio mics used a 4 pin Switchcraft slimline connector like that, used to be called a 2504M. Maybe the old style has the features you need. Here's a pic of an old style 2504....has a flat side whereas the current 4 pin slimline does not. https://www.ebay.com/itm/SWITCHCRAFT-2504M-SL404M-MICROPHONE-PLUG-FOR-BROWNING-GOLDEN-EAGLE-MARK-IV-NOS/153871087788?epid=1901928907&hash=item23d36e78ac:g:3HwAAOSwzrZedC6f Still the extension cable is not a bad deal, it's guaranteed to work...and you get the wire with it! To me, finding the plug wouldn't be the hardest part of making a good coil! Sounds like a fun challenge, and I have built a lot of electronic gear, but i'm happy these days if I can simply go out and buy what I want!🏧🌈
