Higher Frequency Is Most Stable On Gold


Recommended Posts

i found a bunch of Gold ring s white gold , yellow gold ,small and large, from 12k to 14 k on the tarsacci i got a lot of bouncing around on the numbers in 6.5khz and almost non at 18khz most of the rings come in at 04--05-06-07-08 anyone noticed that as well ?

The Salinity Balance setting also plays a part in TID stability & accuracy. Optimal Salt Balance varies with Frequency choice as well as the soil conditions.

I did some testing when i first started out as you can see.   This tight gold notch has some advantage .... targets like DEEP pull tabs/aluminum and iron that wraps around jump to around 27.  A quarter comes in around 20ish.   So if you want to pass coins and pattern hunt in the gold range occasionally its pretty easy to do.  Ive been using it a good while now beach hunting and have to say ive not found a gold ring that read iron.  YOu do get jitter screen..... not so much when the coil is underwater OR passing over a target.  This crude sheet shows 106 gold rings i was using 9khz.

Dew - Can you better explain what you mean by "this tight gold notch" and how you set that up on this machine when your disc notch width is fixed at 6 and you only have one notch setting.  Are you talking a visual TID "eyeball" notch? Thx.

Dew can answer for himself, but I interpret " tight gold notch" meaning the increased quantity of gold rings coming in at 5/6.  Picture the peak in a graph. But I could certainly be wrong.

My question for Dew. I do not own a this detector so have no idea what the numbers mean. If I said alum foil comes in at 44 on my machine it would mean little to you.  I do like your chart, good work. But where does that peak of 5/6  fall?  For reference, at, above, below or same as alum foil? Just above or below US nickel? Some common other reference point?

Here's a partial answer for Flydog.  The US Nickel comes in at 6 when using 9 kHz on the MDT 8000.

This is a chart I created during my early experiments, showing various rings and US coins. (PDF format)

Chase…. Yes I was talking wher the majority of the gold rings hit.  When I said notch ….can pass most iron.  Then in the upper numbers say above 13 I Pass on those.  On the days I’m doing this pattern I watching for pretty solid targets from 1 to 10.  I will likely do it more during recent drop times trying to cover as much water as possible.  In the winter I slow way down concentrating more on deep targets.   
Where does foil hit I’d say 2 to 4.  Deep foil like pull tabs if they are real deep can upscale into the 23 or little higher …oddly above a quarter… but during your slow checking that target may pop a 6 or 7 …. Pull tab just like deep iron which can wrap around to 27ish BUT will show you some neg 26s in there.   I can normally get pretty accurate neck deep where I can’t see the screen …. Just by high vs low tones as well on iron.

Thanks TallTom, good stuff. Looks like nickle or nickle-ish is the sweet spot, at least for the rings Dewcon has been finding. Funny thing is I've recently been working this fresh water beach/grassy park and its extra hard ground to dig ( so not digging all non-ferrous, just coinshootin )and I was getting so many split shot fishing weights masquerading perfectly as nickles that I stopped digging them !  Now I gotta go back and dig all them nickle sigs !

      I finally had a chance to get out with the MDT 8000 again this afternoon. I hunted a different area that is not so heavily iron littered. This was my first chance to run Mixed mode for any length of time. It is much more dynamic & telling than straight Disc mode. I was able to call the big iron & small trash just fine. Dug some nice period targets including an unusual Flat button in very good condition. It is classed as a Patriotic/Political button in Albert's book; PC106A. A pretty neat find for around here.
      Still learning the MDT & playing with Ground balance & Salt balance. Today was 12kHz,  Sens 6-7, TH -3, Disc +30. Not clean ground by any means but only 1-2 nails per sweep instead of a half dozen. This is sticky Red clay with plenty of natural Iron oxide, GB in the high 800's to mid 900's.

      Again the tarsacci finds the deep brass today in a colonial site. Love the machine.  Old stuff including a thimble at about 15 inches down.  Having an issue with the pinpoint button sticking though. Anyone else have this issue??

      I am in a spot i have gone over at least 5 times with the ORX, and the ground went silent. Dont think I dont like the ORX, when i go to the park and sports field you cant beat it .But like i say when i got to the site today I took some advice from a guy who said put the Disc at between 27-and 30  so i set it at 29 and i just was amazed that the ground just lit up . things at 9 inches no problem good signals and deeper . my settings used are .  6.4 khz in mix mode, gain of 7 and 0 threshold, black sand mode on and salt balance at 43,  and this machine just starts devouring the ground ,  I spent my stimulus money on it and dont regret doing so as its made in U,S,A and it went to help an American citizen.   the thing with holes in it was 18 inches deep and i left more in the hole. i was tired of digging deep holes for the day . and i forgot to say i was not digging as many nail false s. so what that guy said must be working

      What settings does everyone else use under the big electrical wires.  The tarsacci wasn’t bad with interference as the deus was in the same area.  But I put the black sand on to get it to quiet down some. Would I be missing targets with these settings?

      Got back to the old homestead i have been hunting, and by far the thing i find the most of is shot gun shells, in fact i found a cash of of them buried about 9" deep , I think a red squirrel buried them  must have been 15 of them , but today I went over the same spot the ORX went over and just kept finding targets, . I keep digging some nails, because i find so few good targets like silver coins i really do not know the difference from a nail false, and a silver coin so i have dug my share of rug pullers,  but the Indian did have a better sound and higher numbers 14-17 and i found it by rechecking a hole the ORX found one in  I am using 6.5 khz and 7 gain and 0 threshold and it will hit with a good signal in air a dime at 11 inches so its got some power . the Indian looks like someone went after it with a sharp punch of some kind, otherwise it was in extra fine condition
