Tip to try for some of your heavily worked coin shooting sites. (SE)

[Doctorcoinz]

I have noticed that on some of my really heavily pounded out sites that by not noise cancelling i seem to find even more coins on sites i thought were cleared out.
I can't say for sure if there is anything to this fluke but i have had better success on certain sites by NOT using noise cancel. Smaller nickel coins and gold rings seem to sound off much better on some sites without the noise cancel used. Also semi auto 22 SEEMS to be a fantastic setting on coin shooting trashy sites when used without noise cancel. Another good tip on heavily pounded coin shooting sites , search in all metal and dig all ferrous targets out including steel bottle tops , the other day i spent some time on a heavily worked site and was digging the ferrous signals out quite a few coins were found laying underneath rusty bottle tops!.. Also a few coins were in the hole with a rusty nut and quite a lot of the ferrous targets that were dug. Tons of good targets are guaranteed to be found by digging the iron out honestly.

it's doing very much the same as what a noise cancel does anyway.

Though, with the SE, by comparison to the EX XS or EX2 , it's is ready go almost immediately when you switch it on and during this short period it has gone through a procedure of noise cancel.

I tend to leave the noise cancel alone these days , i was under the impression that noise cancel should be pressed at switch on but it seems to make no difference wether pressed or not. I seem to get beter sensitivity though by simply switching on and start hunting. I went back to a pounded out site of mine today but found only 1 coin - looks like i have cleared the site out , i have a feeling a ring is hiding somewhere though i will keep digging the remaining trash out over the next year. Once the site is void of ALL signals including trash signals then i will be happy. A missed pulltab could always be that ring that is hiding..

Yes, I feel the same way about pull tabs now as well. I to am revisting sites with the same feeling about targets that are still there.

Given the fact that some pull tabs are very similar to what a half gold sovereign could show up like and yes it could also be a gold ring. I could use CONDUCT sounds to help overcome this possibility but FERROUS sound on this and many other sites is far better at this point in time.

Just realized that when I usually switch any one of my Explorer's on , Most times I get to a site lay the coil to the soil. Switch on and go. BUT what happens if there is any thing under the coil that is of a detectable nature to the Explorer.

As a Noise Cancel requires there to be nothing under the coil when it's initiated. It stands to reason that this should be the case for the Explorer when it just get switched on. You'd have to be sure that there is nothing under the coil at that point that would normally set the Explorer off.

So , one would need to start the Explorer, make sure the spot his coil is resting on is devoid of any targets, switch the Explorer off place the coil back on that spot on again and switch it on.

I have also switched Explorer on without initially placing the coil to the ground but in the air. Then I have started detecting.

I've got to take note of this in the future.

Wonder if its what makes that big a difference to the Explorers function and finding ability and why there might be, as you suggest, a better sensitivity.

When you say you find coins under the ferrous, does this include low tones? Or are you just digging the iron out and checking? Do you dig the all the low tones? Or do you only dig when a high tone ever so slight is mixed in? Do you concentrate only on the nickel type of low tones? Or are you digging deep stuff down in the foil range?

No need to respond on all - but just wondering if I can get a strategy or two to use in a few spots.

So much for round targets.

The noise cancel is doing nothing but canceling out any electrical interference in the immediate area. Its not doing any ground balancing as that is done automatically with the Explorer line. Clearing an area of junk targets will always help in producing a clear good target signal that has been masked by a junk target. Use a 6 inch coil in these areas.

 

[NH Bob]

Again you are confusing noise cancel with GB. Noise cancel is for outside electrical interference and GB is taken care of by the Explorer.
With the Explorer XS & XSII you find a clean spot to noise cancel after initial start up, set the coil on the ground and cancel. With the SE you do the same startup but lift the coil off the ground to noise cancel and if possible you face in the direction of the interference and then cancel.

 

[Hard Nosed Dave]

I'm not confusing anything again, at least I am not trying to.................. I know what GB(ground balance ) is very well. I have not mentioned anything about GB(ground balance) or that it has has anything to do with Noise Cancel in my last or any other post that I have ever made that relates to the Explorer line of detectors.

In the case of the Explorer SE and probably in the previous models , such factors of the ground conditions or the way the Explorer deals with such conditions, is possibly the same as doing a or dealing with "GB".

The most likely equal to GB is this reference found in the Explorer SE manual (maybe it should be call a GC):

"Ground Compensation

The Explorer SE uses a sophisticated
approach to the elimination of ground
mineralization. It uses advanced digital
filtering to eliminate the influence of
ground signals."

You'd think though, that if it was GB, that Minelab would have simply called it GB.



Given that ALL suggestions are that a Noise Cancel is actually part of the way it calculates for Ground Compensation, it is most likely a similar to what a GB is. None the less, it still does more than just deal with a presumed electrical interference being present or not which is not the only consideration that the Explorer is making when doing a Noise Cancel.

The user manual for the Explorer SE says it clearly: Page 57

I quote from this good book:

"Hold the detector 30cm above the
ground, making sure there are no
large targets or obvious electrical
interferences close by."

Granted that it refers to large targets but why take a chance on deciding what is or is not a large target. I believe that no target could be better as a small target might also cause a problem( how small is a "small" target).
Also that
"The NOISE CANCEL button instructs the detector to automatically listen to every channel and select the quietest
channel due to outside interference" Stands true BUT I am led to believe from what I have read and from my own experience and that of others, that when first switched on the Explorer SE takes into account most outside interferences and factors them into it's startup and how it should function relevant to electrical interferences or obvious large metal objects.

What about the not so obvious large metal objects that may lay just under the soil. They also need to be taken into account even if you are 30cm about them or near them.


The same goes for the Ex XS or Ex2 that goes through it's start up mode. It's "looking around" for any problems that may interfere on startup.

Your suggestion that:

"With the SE you do the same startup but lift the coil off the ground to noise cancel and if possible you face in the direction of the interference and then cancel." is possibly an idea that you or some others may have come up with."

This is where I think you are actually confused.

It's not a correct or the suggested procedure in the user manual, but it might work for you. '

So the question goes begging that " If there are any objects present within the Explorer's coils' area of detection during a start up or when doing a Noise Cancel , will it influence the Explorers ability to detect correctly.?

It probably does, seeing as you are advised not to do a Noise Cancel, where there would be a large metal object(I say small as well) within 30cm, then this might also be a consideration when you are about to switch the Explorer to ON either with coil 30cm off the ground of sitting directly on it.


Take care

My information came direct from a Minelab Representative. When I called about my first SE and its problems.
Also if you start your machine over a large target it will automatically sound off letting you know.
None of us are truly experts at mastering any of the new problems the SE has brought with it, but we can put to use and share what we have found that works.
I am no more right or wrong than you or anyone else that has found a way to make this mew machine respond the way we would like.

Also I may have stated something that looks like it was directed to you in particular but in all reality. My post or response was in general.

My XS get better depth if the noise menu is set on 1.
