Falsing issues

There has been a lot of talk on falsing.
I was always under the impression that the Explorers did not like air. So I aways kept the coil on the ground or as close as possible. Scrub the ground was the way I was taught.
With the new SE on page 19 in your manual it states (The SE will perform at its best when the coil is kept close to the ground. Avoid excessive brushing of the coil on the ground as this may cause falsing.
 
Keeping the coil off the ground is something new that should have been posted more clearly by the powers to be.
 
Whoever wrote that 'hold the coil above the ground' in the manual needs to get up from their desk and go out in the field and dig a couple thousand targets with the machine.

First off, an inch or two of air space IS enough to lose the signal on many deep targets so bad idea. Second, the coil is shielded against the static charge of rubbing on the ground. Rub your coil on some grass like you are trying to start a fire, guess what will happen...nothing. The shielding routes that static charge away to ground. If there is a bare spot in the shielding then it will false like a mother, but such a coil would be considered defective.

The Explorer also doesn't like targets in valleys where there is a target in a valley between two clumps of sod e.g. the outer edges of the coil are on the peaks and there is a couple inch air space in the valley over the target.

Charles, I'm hunting a corn field with my SE and the peaks and valleys don't seem to be bothering it at all. He's got crushed and broken corn stalks in piles and furrows and valleys and I just follow their contour as best as I can. The only time I get a false is when I bump a standing corn stalk to hard with the edge of my coil, even then, I can tell I created the false and ignore it. Same thing at the beach, if I hit the bottom of the coil on the wet sand she would false, but after a while it became easier to tell when I had done it. Auto sens -32, fast on, deep off, gain 5, clean cover, volume 10, variable 10, iron mask a quarter of an inch from the left side of the screen, ferrous tones, threshold pitch 4, threshold volume I think 8, Sun Ray 8 inch, or stock ten (little harder to follow the peaks and valleys)
 
The peak/valley thing is common to the XS and II models, not sure about the SE. If there is a rusty nail in the valley, it very often will false high. Don't ask me why, its just one of those weird things that happen. If you can get the coil down in the valley flat the false disappears and the tone goes low iron.
 
In a way I wish I had a video camera with me.
Let me start with my settings.
All metal - sen. at 30 in auto - Ferris and the rest wouldn't matter.
I banged the coil off bushes and small stumps with no falsing. the only time I could experience any falsing was when I swung the coil over fare sized iron and then it was the high tone of silver. Once I swept back over it it came in as iron tone. If I took the time to play over the iron I could get it to high tone like a quarter. You know what I'm talking about. This machine is very stable and air tests with good depth. Haven't had the pleasure of digging a deep target yet but am very confident in the new SE.
Bottom line is the iron falsing with a high tone in the initial swing at a moderately fast swing is stereotypical of a Minelab product. As the XT70 does the same thing.
When hunting in AM I feel comfortable enough with the tones so the falsing that I'm experiencing doesn't bother me as I can pretty much tell the difference.

Bob-- For me, here in Oregon. If I were to run Auto-Sens, I would have never had the pleasure of digging a deeper keeper either..
 
I normally run manual sen as high as I can get without the jitters.
I've had all the Explorers and am well accustomed to how the run. This is my second SE. The first one was so sensitive you could not hunt near city limits.
 
I'd be careful with this...I think most times the machine over-corrects and gives you too low a sensitivity, just for the sake of a stable background. And you don't have a clue re. what the actual sensitivity is.
Yeah, it sounds nice, but I prefer getting used to the normal 'squeaks and squawks' that are part of the Minelab experience. You will learn to hear right through these for the good-target sounds. (And when in doubt, check if there's a real target there with Pinpoint mode.) The only time I've used 'auto' is with killer black sand, where I hope to find coins in the top inch or two by sweeping VERY slowly.
 
Since the forum format changed over awhile back or server crash or whatever happened .... anyway there was way more than enough archived information to remedy these kind of questions. It went back several YEARS :)
I've been using an Explorer as long as anybody and have never known it to be GOOD advise to hunt with the coil above the ground ... never!
The Explorer does NOT like air gaps between the coil and will certainly lose depth. I don't care what the manual says, it's a well known fact that the Explorer doesn't like an air gap and it doesn't air test well either ... but it's killer in the ground.
It has never been known for liking disturbed ground either, it's designed for naturally lost coin size objects that we're not plowed up to the surface. Yes it will still hit on them if they remain inside the original dirt clump but disturbed ground is NOT the Explorers strong suit.... that's one of the negative things about multi frequency units, they don't like disturbed ground and they demand a slower hunt speed to process the information.
About the auto sens vs locked sens setting, there have been some mighty talented Explorer users frequent this forum over the years and it's ALWAY'S been a toss up as to which setting works BEST. It pretty much came out to a 50/50 result as best I remember, so there is no "this setting fits all answer" IMO.
All of this is purely site dependent and up to the USER to understand what will work best on their site/situation at hand ... pure and simple !
Sorry folks, don't mean to sound like I'm a know it all or lecturing anyone but all of this stuff has been discussed many times over.
I just wish those old archives still existed for all of the new folks as it was filled with everything one could imagine, sounds, screen pics, iffy target sounds,tons of custom set-ups and well ... you name it.

I'd be careful listening to that advice, the Explorers of the past had a slower processor and that was the main reason the auto sensitivity lost you depth. My SE actually finds deeper targets in auto sensitivity and is way more stable in auto too. I've tested it at sites on undug targets and in all but 1 site the machine simply picked a better sensitivity than I could and in no site was I able to set it in manual and leave it alone with out it starting to false or loosing depth. I repeat, I actually loose depth in manual while auto produces consistently, even when I went to a black sand beach. I have seen a lot of posts on this form on this topic "don't use auto sensitivity because you'll loose depth" Does anyone really know this for sure or proved it in some way?????? Or do they just carry that over from their experience with their previous Explorers??? Not trying to correct you but many things are read and then repeated on this form without anyone really testing it out for themselves. Unless I have a machine that's an oddity, my testing over and over went to auto as simply more consistent and better depth overall.
 
But what was cool is I just took my foot and smeared down the high point to widen the valley and swung over again. 81 times repeating iron false signal gone, two times silver repeated tone, one was the 1900 barber half the other a 1877 seated dime. Worth the effort. When I first started in this field on the first day I dug those iffy's, hell, I dug everything, ended up with 6 coins and enough nails to build a house. Today, four days later, I dug 20 coins and two nails which I new deep in my heart were nails but because they were deep, I took a chance.
 
I know you're a very capable hunter, most of what I posted was really for the new detectorist. :)
Even though I've been using an Explorer for years I religiously READ the manuals on every new model, no matter what name brand is on it.
The manual is WRONG in my opinion but everybody can and should hunt the way they feel comfortable with.
I do know that hunting with the coil above the ground with my SE will cause it to suffer a lot when testing in my coin garden.
For every 1" that I hold the coil off the ground it loses 2" real depth in the dirt ... so I'm convinced that a misprint was made.

Never mind what's a park hunter supposed to do, hold the coil off the grass 3-4 inches from the ground so it doesn't touch anything? Good luck getting any depth with that approach.

They have tweaked the machine to be sure but I doubt it is fundementally changed from prior Explorers in this regard.
