Great info from everybody. Gear Box, excellent post and testing too...Can I ask...what kind of soil do you have? I'm thinking the "final answer" on this might be different for everybody depending on their soil. In low mineral soil a fast(er) sweep speed might see things deeper maybe, and maybe in medium to heavier minerals slow is going to see the deepest? Also, as others have said, perhaps the coil changes that a bit too, as well as the level of sensitivity. For sure if I'm riding a high and somewhat unstable sensitivity I have to crawl or the threshold will drop out. My soil ranges from lower mineral sites to heavy ones.
More testing is for sure in order on undug targets. Sticking a coin in the ground disturbed the ground matrix, so in fact it might alter the general hunting long sweep speed one way or the other. Of course when finding super deep targets to test on, that precludes the fact that you might not find the super deep stuff if say using a faster sweep while hunting, where as a slow one might be seeing stuff a bit deeper. If anything, when hunting at a somewhat faster sweep speed one might want to pay attention to any nulls and then slow down over those and see if a tone comes out of it. And, by the same token, when hunting at a really slow crawl one might want to pay attention to any nulls or threshold changes and then try a faster long sweep over those and see if a tone comes out.
On any machine when a coin gets to the very edge of detection depth it begins to read down into the iron range, due to the signal being too weak to overcome the microscopic iron content in the ground (all grounds have microscopic iron in them to one degree or another). On the Sovereign of course when it's at this kind of fringe depth you may only get a null over the coin at first due to the iron overpowering the signal or pulling it down into the iron range. So it might be worth noting coin sized nulls and trying various long sweeps at different speeds and seeing if a tone comes out of it.
Now, there is a fine line between proper target 180 ID and a coin just at the outter edges of that detection depth that will only try to climb or at least bounce around in the lower numbers as you wiggle over it. The key is if it sounds soft enough to be deep enough to be giving you that kind of ID trouble. If it doesn't sound deep enough and is bouncing around in lower numbers then it's probably an odd shaped piece of trash. But if it sounds deep enough and is doing that, or especially if you can see it's trying to climb, then it could very well be a super deep coin. Another key I think is listening to the audio. It should be giving hints of a high coin tone in it here and there as it bounces around or is trying to climb.
But, beyond that certain ID trouble fringe depth, the even more fringe very outreaches of the detection field is where the coin might only null. Those are the ones that long sweep speed while hunting might be the most critical on, and I'm sure it's either going to be a super slow crawl or a somewhat fast(er) (say up to about medium speed) that is able to see that target with some kind of response other than a null.
Not saying that super deep stuff that doesn't null isn't worth checking these sweep speeds on, as I'm sure those too will show you one way or the other what speed the Sovereign wants for best depth while in general search mode.
I'm also sure that, regardless of how slow or fast(er) your sweep needs to be, the key to pulling the best tone and ID out of a super deep target is by doing the wiggles or super short sweeps over it, and usually it wants this at a faster or even fast pace. The most logicial reason for this is that by keeping the coil in that small patch of ground you are isolating it from changing ground signals (not targets, but the ground signal), and thus the machine is ignoring the ground with no need to be resetting or changing it's ground canceling abilities, and so is able to see and pull the best ID and tone out of the target.
That reasoning, if sound, might support that a super slow sweep speed is seeing the deepest, because you are giving the machine time to read and adjust to the ground as the coil moves along in it's sweep, and so is able to ignore it as best as possible and see a super deep coin. Then, on the other hand, in really good neutral soil this might not be an issue, so a somewhat fast(er) sweep speed will see super deep stuff better maybe. But the key here is that while this initial hit might be harder, does that mean it's really seeing targets deeper than a super slow crawl? That's the debate in my head, and the very reason for this thread.
Enjoyed reading the debate, and hope to read more. As you guys know I love to read and type, but especially today I'm thankful for good friends and good reading like this because it's keeping my mind off my dog, for at least a few minutes at a time anyway. Any breather or rest, even for a few minutes, is welcome and helps me to make that one step at a time to "live on", so once again thanks for some good reading.

nice video thank you.
a couple of questions:
1. sounds like your run your threshold high, might just be the vid?
2. at about 1:18 in the vid on a right to left swing which is slow you do get a hit and I notice are now scrubbing the coil. how high off the ground was the coil on the other swings.
3. with such a strong response and as you say neutral ground, you should have easily been able to bring up a 180 on your meter, but it bounced all over the place. if you tightened up that swing can you get a 180 on those coins, they are well within range?
I think youve got to tailor your swing speed to each location/situation but by experience I would never hunt at the speed you were swinging at in the beginning of your vid. by my experience that would only net me shallow coins at best....and that could be my soil/where I hunt, but what else can I speak of
[/quote]
Neil, I had the threshold higher for the camera, I usually run it just high enough for me to hear. It would drive me nuts listening to it up that loud
I remember lowering the coil so the viewer would know I wasn't raising it up when I went slower.
I can't get the meter to rise to 180 on the 8-9" coin. About 150 is max. If I do the wiggle over it the numbers start to climb but resets. It is likely my inconsistancy but I have worked the coins a lot and never been able to walk it up much higher than 150.
I probably should have left the meter off but for some reason I flipped it on.
You're absolutly right about tailoring the swing to ground conditions and thats what I have been prefacing in my post. But the facts are, the Sovereign is not a PI detector and the slower you go does not give better depth like a PI machine.
We may have to go slower because of ground conditions, but slower doesn't give better depth.

It is good you did this test like it should be done on actual targets and that you see what many of us have seen. My sensitivity is mainly at the 10-11 o'clock position as I find this works the best for me too. When detecting with my Sovereign I run a slow speed (Probably 1 foot a second)so I can hear the signals come and go, if it is nulling most of the time I know I have to go slower to hear the good targets in with the other targets as the detector has to have time to see them if I want the coins I look for. Now in the areas i know have been worked hard I go at a snails pace as i want to hear everything that is there and this is where going super slow gets me the deeper targets and where i see coins that are over 8 inches deep and some as deep as 13 inches too. If I swing any faster there is no signal at all and possibly a null. The one park I did this at around the trees my only coins that were not deep were the new coins and those that deep were all over 8 inches deep with most at 10-12 inches deep and one at 13+ inches deep. The coins were all pennies,dimes and nickles, no big coins at all. If i remember correctly there was 24 new coins and 76 old coins found in about 14 hours of detecting.
Keep trying the slow swing in the older areas and when you get a weak signal swing faster and please report your results.
Good luck and thanks for posting your results

Ism thank you for replying to each question. Ive never seen a sov meter work like that, can you get a 180 reading on a dime out of the ground?
Even though I watched your vid I do believe a slower sweep will yield deeper finds and more finds. I cannot explain your video but certainly something is going on to make that meter jump around the way it does, unless you have a faulty meter or your ground isnt as neutral as you might think. any way I cannot argue with your results and do not think your lying about the depths or targets buried in the ground.
Since you like testing you might try burying a piece of paperclip/iron wire an inch or so off to the sides of the coin in several directions and play around like that and see what you come up with. see how it changes your response, if it does. thanks again, Neil
Any chance your in NJ?

I am still learning the GT and will be for a long time. I sweep a 2 second sweep but I hunt wet salt sand. I do the wiggle if I get a blip, whisper or blip null. I change direction and slow sweep from both directions and then wiggle after the threshold changes, once from the right ten the left. I wait for the threshold to come back before sweeping the other way. Also, a null does not always mean it is iron. Deep good targets like gold rings can do this as well as coins. Maybe that is why an area seems to never be hunted out? A change in soil moisture could be all the difference between a null and a whisper to make you dig it.
ISM and you other hunters. If you post on FMDF then please start a thread there in the water hunting section. If you don't then I will. There are a lot of great hunters there who will put their experience online. I wanted to post your video but won't do it without your permission. I really think your video makes a statement that is hard to ignore. Thanks!

Neil, I usually use dimes for testing because they seem to be a standard for most people. My meter will get a 180 on a dime at 6-7 inches. For instance, if I go slow and hear a high pitch signal, I can go back and do the wiggle and get the 180 easy. But if I go faster (not too fast mind you), I can get a deeper target but cant get the 180. It is broken up but I can get it to rise in the area of a 150. This is because I am at the extreme range of detection for "my GT". I am in Michigan and my soil is almost yellow sand, barely any top soil. The only thing that grows in my yard are weeds...errrr exotic grasses. I tried to plant a garden once and its not gonna happen unless I truck in top soil.
BTW, all my VLF detectors do this.

LOL exotic grasses, got plenty of them in my yard also
I can get a good coin reading down to about 12" on either my Sov or Etrac at the beach (ocean or freshwater), you have to concentrate on the signal, isolate it up well, but usually is correct and on the sov will get to 180, on the etrac depends on the coin. I guess our soil here is mild, some beaches are alot worse and tough to get accurate numbers even in the 6" range. thanks!

Neil, I picked up a Used Deus, on its screen is an earth mineralization scale. At first I didn't think it worked but there's an area in my yard that I threw some Arizona dirt. I got a reading over it.
Long story short, my soil is zero mineralization on the scale. I soaked the yard yesterday and will cover it for an hour or so this morning and then test with the GT to see if moisture changes anything.
I will video it just in case but I don't think the results will be any different. I have been testing this off and on with my GT since February because of the reports and comments made about real slow sweep speed.
Thanks for the feedback

Ran thanks much. Awhile back I had an F75 that had some kind of mineralization meter on it also but I dont remember how it read on the beaches I hunt. If your gonna test some more toss in some small iron close to your targets and see how that effects your results, see if small iron even makes the sov null at depth and might just blank out a target completely (kinda like a silent search machine). Neil
After soaking the soil, I tried the Sov over the same dimes and got the same results. I'm not sure about the test area because of the EMI from a buried cable TV line. Its really bad within 25 ft of it and this area is about 50-60ft away.
It could be the reason my deeper targets are real jumpy when I do the wiggle. I can never get a stable number. On the 6" dime I get a nice 180. I removed the meter cable and went directly into the box with the coil cable to see if that was an EMI weak spot but it didn't change a thing. As for the nails, I was going to make an area like that for testing but I never got around to it. I will give it a try

That buried cable will destroy results and especially VDI stability. One of the test gardens I did one time I had big plans for. Spent an hour or two sticking silver dimes, a silver ring, buffalos, and wheats all at different deeper and deeper depths by inches at a time. Even had a washington and a dime in two different spots on edge at vairing angles at about 9" or so. All done. Proud of myself....Until a few weeks later when I decided to test it for the first time, and realized I had done it right under some over head power lines! Was USELESS. Luckily I had marked each spot via a patio stone about a foot away from each target and made a map and notes as to what each was and at what depth, so one day when I was hard up for money I dug all that stuff up and cashed in the silver. Had to use my Pro Pointer and a large shovel to find them. This was of course done on private property where there is no issue to using a shovel.

Did some thinking and got a fly in the ointment in terms of what the "wiggle" or short sweep does. Regardless of how the target is found, once it's found on the GT your best audio and ID is by doing real short constant sweeps or "wiggles" over the target to pull the best ID/tone out of it. Why? It's been speculated that it's isolating the ground signal from the surrounding ground and so can ID the target easier without the hassle of having to change the ground balance. That could be, but I've seen the same need to short sweep or "wiggle" over deep stuff to achieve best ID on other detectors such as the QXT with a locked ground balance, so that kind of eliminates that stab in the dark. While the Minelab isn't using "auto tracking", it does adjust for the ground conditions in it's own unique (and much better than Auto tracking) way while hunting, unlike a fixed ground balance.

OK - been reading this whole thread and must say very interesting. I can say that in my short time using the GT i have found that I can hit a target while sweeping and then stop to check. Then the target goes away. So I re-sweep at the original sweep speed witch is often faster then my stop and check speed, result is with faster resweep I hear the target. So my intuition tells me that some speed of motion is needed to get the response at depth. Once I have narrowed down the location I can zero in with the wiggle. So again it appears there is some speed that gets the target. Have not tried faster but my guess is too slow or too fast result in the same thing no target. So there is a sweet spot it seems. Now like some have said that sweet spot could change with soil and depth. Maybe I need to put a metronome on the detector and measure the speed and change it up and down to see what happens then I can have real numbers based on the beat of the metronome.
On the wiggle - it is my guess but I think what happens is the area gets better saturation of the transmitted signal as a result the detection side has more information to process. Here is an analogy assume you have a flash light that only works when it is moving. So if you stop and shine it at one spot the light goes out. So imagine you are in a dark room and you want to make out something on the wall. By making short back and forth movements of the flashlight you can better illuminate the area on the wall and see what it is you are concentrating the light in a very small area and though the light is moving the result is more like you had the light fixed on the spot and were not moving. If you sweep a larger area the intensity of the light on the target area on the wall will go down. So the shorter and faster your sweeps the more light will be concentrated on the target.
I think that is what happens with the wiggle you better illuminate the target by the short concentrated sweeps allowing the detector to better see the target. That is why the tighter and shorter the wiggle the better the depth you are concentrating the transmitted signal and are better illuminating the target.

This I will tell you from experience digging those deep coins other detectors can not see. The reason is the Sovereign has to see them to be able to tell you something is there as these signals are small and by going faster it can not even see them. Now on those targets that are not deep the signal is much bigger and sweeping a little faster will still see them with no problem if there is not a lot of iron around as when it is in a null from iron it has a longer way to go to give a signal.
Once you find a tone you want to check out and by going over just the area where the target is it will amplify that signal to make it easier to hear, but if you go past the target with a longer swing and hit another target it will make it harder to get a good ID on the one you want to ID.
Take time and experience and willing to learn something new each and every time out to get the full benefits from a Sovereign, just ask those that have a lot of successful experience in actual hunts with the Sovereign.
Good Luck

One thing I did not mention is my sweep speed is pretty slow to start with. So my guess is when I was stopping I was maybe going to slow, but then again there are times when I go real slow and it almost seems the GT is tracing a picture of the target. Have found real slow can often tell if I have a coin or a pop can by how the tone draws out different. The more you use the sovereign the more she seems to talk to you. B r y a n n n a that is a pop can keep on walking

Maybe that doesn't count as successful experience in actual hunts to some, but it does in my book.
Bryannagirl, I'm not the first person to say that they *might* get better depth with a somewhat faster sweep speed. I think it may come down to the kind of soil being hunted and the sensitivity level. Super high sensitivity near the edge of stability= slower sweep. Still, I'm not convinced one way or the other yet myself that a approaching medium speed might give better depth in some situations. As I said before, it might just be that the initial hit is harder, but it might be that a super slow sweep is actually getting deeper even if the initial hit isn't as hard. I've got more testing on undug targets in the field to do before I decide one way or the other. I also plan to grid a small area with known deep targets with a faster sweep (approaching medium) and then will re-grid it with a super slow crawl and see if one misses targets the other didn't because of depth. Problem is you've got to find a really deep target first to test the general sweep speed with a normal long hunting sweep over it to judge, and if one is deeper than the other then that can be exclusive to the test. Most people, including the old pros using the FBS machines, say that the slower the better for max depth. There must be something to that so I lean that way myself until I prove to myself otherwise. The sweep has to be long like your are hunting though, because the short sweep/wiggling over a deep target to pull best ID out of it wants a faster motion of the coil. I'm talking about the long sweep you'd be using while hunting. That's where I'm curious if a super slow crawl gives best depth or a somewhat faster one does *in my soil*.
by getting a deep signal and trying different speeds on your swing of the coil. I find this works the best in those well worked area that is known for deeper targets like those 100 + year old parks where everyone says is worked out, but you can prove them otherwise.
A slow steady sweep speed and listening to every little tone you get and if you know your Sovereign well you will notice those little tones that stand that are higher pitched, but if you speed up the coil just a little they will be gone as it don't have the time to see them. This is not a method to use for clad hunting, but for those older well worked area where we feel there is coins over 7 inches deep. I sure do wish I was able to travel around to demonstrate this to others to show how this works out for me, so much easier to show this than explain this.
A slow steady sweep speed and listening to every little tone you get and if you know your Sovereign well you will notice those little tones that stand that are higher pitched, but if you speed up the coil just a little they will be gone as it don't have the time to see them.

What Rick just said is what I have found out and tried to express in my above post. I'm so confident in the slow sweep and slow forward movements that I will not deviate from it any time soon. My recent old coins have proven this out. Good info from everyone here thanks.
Good luck Gary
