  1. Who's going to be the first to use a drone scout up that wash that you'd love to hike up but crap it's warm your old it's nearly vertical geewhiz I still like to have a look!

    Seriously Dash anybody thinking of using drones to scout out likely New terrain?

  2. Relic hunters like the bunch who attend Digging in Virginia" will benefit from this since ultimate depth in hot VA soil is their major interest.

    I take it that when you say reintroduction, you mean that the 4500 will stay in the lineup and that this is not just the disposal of excess inventory. Good news for prospectors.

  3. I think I posted this here before – I certainly posted it somewhere before – but I had an original TDI and I now have one with Reg's mods and the difference is like night and day. Beautiful smooth threshold iand a bit more depth.

    Thanks Reg.

  4. A pal of mine just sold an SDC2300 for $2000 (asking - don't know if he got that much) on Craigslist in Phoenix.

    Guess it's not only the price of gold that is dropping.

    It's not just gold detectors however. I have bought and sold a couple of dozen detectors in the past 18 months or so and the price of used detectors is really "soft" right now.

    I just got offered four absolutely beautiful Italian Suits in my size at a gas station in Abu Dhabi for $800 - so I guess things are tough all over - but that's another story!

  5. So Fisher was willing to send you two replacement units (one coil replacement- one complete replacement) at no cost to you for shipping either way; based on your findings on air testing under conditions completely unknown to them. Pretty good I'd say.

    I'm sorry to hear that you were inconvenienced, I'm sure it was frustrating, but except for the original unit, it appears that none of the others were actually defective, just not up to the standards you had set.

    It is a sad fact that almost all makes of detectors exhibit considerable unit to unit variation, much like I remember was true for rifle accuracy when I was into that stuff - some rifles of a certian make and caliber were tack drivers and others were not.

    I am pleased to hear that Fisher went the extra mile to satisfy your expectations. I'm sure whoever buys it will thank you for your trouble.

    One advantage to dealing with a local dealer is that you can probably do your air testing before you buy!

  6. Actually, "Woof" is one of the "handles" under which Dave Johnson (Chief Designer) at Fisher, etc.) posts on a MD forum. Given the number of gold detectors Dave has designed, I guess he is sort of the champion gold detecting "Woofer"!

    I have met him however, and he's not nearly as cute as the little rat in the picture!

  7. One comment to a post above.

    The TDI control box is heavy gauge aluminum, it is held my four stainless steel screws to a thick aluminum flange which is firmly attached to the rod. Of course, I guess it could have come loose somehow due to sliding sideways to the ground. Even if it did however, it still has the ability to be body mounted.

    Just sayin!

  8. Pic showing four out of a total of 10 gold bracelets or armbands or the like which a detecting pair found in one field in Denmark. Total weight of gold is 3.5 kg or 7.7 pounds - 113 ounces troy.

    3,500 one gram nuggets - ouch!

    These object are from the Bronze Age - 1500 - 500 BC

    Only catch. By law in Denmark this is National Heritage Treasure. The finders and the landowner will recieve a payment based on the value of the metal.

  9. John,

    I think you will find that the F75 has undergone pretty much continuous development since it was introduced. The original was probably the most powerful VLF detector onmthe market, but that power could not be used where EMI was an issue. Apparently design changes were made on an ongoing basis in software and perhaps hardware to improve EMI resistance.

    A new model with Boost Process (somewhat confusingly called either LTD or SE) was introduced,some time ago and in 2014 there has just been a significant upgrade of this model with the addition of DST noise reduction.

    My new F75 is incredibly sensitive and can run at 99 sensitivity in my EMI hellish environment with minimum fuss if I select the quietest frequency.

    I do suspect, however that mechanical engineering of the detectors has not been their strongest suit. This seems to be improving. KeithnSouthern has tested the new F44 and he raved about the solid air of quality that the detector has. So hopefully the hardware issues are going away.

  10. A couple of recent posts referred to the whites TDI – so I thought I'd pass along the following.

    Last week I purchased a secondhand TDI from a guy who had sent it in to have Reg Sniff's noise reduction mod done - along with replacement of the op-amp.

    I had a TDI previously and the difference between that one and this one is like night and day. My old one had a warbly threshold that drove me nuts and made it very difficult to use the sensitivity higher than about 2/3 of full. My house is EMI hell, the neighborhood has underground utility service and the transformers sit on the ground. Even mildmannered VLF's like Whites Classics go nuts here at full sensitivity.

    This TDI has a silky smooth threshold with just an occasional blip at full sensitivity (12). It also air tests 17" on a nickle with the standard 12" DP coil! That's 4" more than I ever got with my old TDI here at the house with the same coil.

    I have been playing with the silver coin hunter trick with the high conductor mode selected and the GB offset to kill all ferrous. It really works - with the GB on 4, I hear no iron - and a quarter that I buried down 8" about 5 years ago gets a good signal with 2-3" air gap even using a 10" elliptical Coiltec mono.

    Now I need to find a dead Bigfoot coil and build a mono PI "Bigfoot".



    The mods were $125. Reg could probably furnish current details.

  11. Loose treasure makes some folks crazy. When gold was the "cash crop" robbery, murder and mayhem were the rule. It was sorted out by better government and better law enforcement. Of course the enforcement preceded the government when the "barons" ran off the small timers. Good government sorted that out.

    Now we have poor government and selective law enforcement. In my opinion a bad combination.
