Holy nulling batman !!!

[MNCoinhunter]

This afternoon I went back to the spot where I found that 10K gold necklace. Snow had melted away and opened up a huge area where I had found Indian and wheat pennies last year. Frustrating as heck....I could go barely an inch in any direction without nulling. I was basically hopping my coil along the ground in half-inch increments to squeeze any decent signals out of the ground. Has anyone else encountered this? I suppose all a guy can do is creep along and hope for the best.

YES! At times, in certain spots, I'm finding that the nulling is INSANE! I know opening up the screen will reduce the nulling, but MAN. Hunting with the factory coins pattern, in trashy areas -- the amount of nulling is crazy sometimes and I'm not sure how to deal with it.

Yes, I even tried experimenting with Iron Mask set at 26, and it was still nulling out constantly. When I had my Ace 250 there last fall, I could discriminate iron out and there was no tone, which was a lot easier to deal with.

It seems like it's taking longer for the threshold tone to come back. I can only guess that this place is going to require a lot more patience on my part.

[size=large]I'm curious whether the small coils would work better. like the sun-ray x-5. i tried a very trashy lot with the 8x6 sef and i couldn't find a thing. just
trash. will be trying my whites 5.3 there next and hope to find, at the least, a Lincoln penny. if that works then i may get the x-5 for my se.

I would love to have a second coil like the Sunray X-5, but I'm still getting used to the stock coil and the Explorer as a whole. You may be right though, I might have to leave this spot alone until I get better with this detector, and/or buy a second smaller coil.

try all metal ferrous sounds at this spot the nulls will become low burbs recover faster look for those quick high tones then just minelab wiggle them out pinpoint don,t work well in all that iron just locks on iron slow wiggle can sniff the goodies out i do this in iron in fested spot at old colonial sites to find old coppers it works

I though my understanding was that it would still pick up coins even when it nulling.I have two ares like that and still found coins.Drives you nuts though.I know when it nulling and you are waiting for threshold to return the machine is trying to reset.I thought steve {ms]said this i could be wrong.http://www.findmall.com/read.php?10,1405605,1412728#msg-1412728

Thanks guys...

 

[sgoss66]

Thanks for that info, teleman -- are you saying that you usually hunt conductive sounds, but when in thick iron you switch to ferrous -- and that it will then "recover faster?" Interesting...

ohio fred -- thanks for the link; I re-read that and find it interesting. I really want to understand more about what the machine is doing/not doing when in a "null."

Hey Bryce,

Thanks SO MUCH for that link. While I can certainly understand and appreciate BELL's approach in that thread (open screen, ferrous sounds), I -- like you -- would rather not hear all the commotion my machine would want to make in an "open screen" setup in a trashy area. That "sound overload" is part of what I am trying to get AWAY from (part of the reason I switched from another machine to the SE Pro). Your testimonials of finding silver through long, sustained nulls is VERY interesting, VERY encouraging, and VERY helpful. So do you feel that there is actually NOT a significantly "slower recovery" when the machine is nulling, versus running an open screen?

Finally, it sounds like, to me, that what you are saying is that the only change you make, when encountering a spot of ground where you are getting long, sustained nulls, is to slow down even more, and move slowly through that patch of dirt -- but otherwise, you just treat the null as an indication that iron is present, and nothing more?

Thanks!

Steve

Thanks Bryce......there's that learning curve smacking me in the back of the head again..lol !

 

[Hotcz70]

Steve...to be perfetly honest it doesn't matter to me whether it is slower...faster...same...etc. It doesn't even concern me...because even in the heaviest trash or iron I NEVER turn fast on because it chops the sweet sound short that I like to hear. I just slow way down and listen for the sweet warble to bang out of the trash sounds...or out of the silence of iron if the case may be.

As for the second question...yes. When I encounter long nulls...a big yellow caution flag slaps me upside my melon and tells me to slow down from an already slow crawl...to an even slower creep

Bryce,,, please tell me if I am wrong,
The "Nulling" is not only iron,, but everything that is Discriminated out, right ???
The blacker the screen and the bigger the coil,in a area with more bad targets,, the more "Nulling" one will have..Right ???
And the more targets that are close together.. calls for a smaller coil,,,Right ???
And you just about can not go to slow.

McDave, said that the Snow had melted, so I think the ground was damp, I will take damp ground over bone dry ground....
Back in my old Sovereign days.. I learned wet ground helps a lot... Seems like the detector has better sensitivity to targets.

[sgoss66]

Bryce -- thanks for slapping ME upside MY melon! I need that, also! I'll remember to slow down EVEN MORE when I hit nulling, and to keep fast "off," too.

BJ -- I have guessed that the nulling IS "anything" you have disced out; guess we'll see if we are wrong. As for the wet ground, I can confirm that it helps. I simply CANNOT see coins in my test garden right now, with the ground dry as a bone, that I could see NO PROBLEM when the soil was moist. I'm SHOCKED at the difference.

[BJ in Okla.]

The ground is so dry from the lack of rain, are we going back to the dust bowl days ???

I hope that we get some rain very soon...

HH...BJ

 

[sgoss66]

Let's hope we get some rain...the Southern Plains region is REALLY dry...

I hunt in what ever method helps since i hunt in various sites. In the fields i may go from cond to ferr just because coppers sound better and you arent messing with pull tabs and a lot of can slaw. BUT.... thou you do get low tones on iron... the trade off is rust and hot rocks that hit in the lower right corner gives you a squeal. It can be as annoying as the high iron tones in cond. In parks i do open up the IM to just above where iron begins to null.... somewhere around IM 26. Everyone says the MLs have a slow processor..... if you believe that open up to AM and creap along you cant stand all the targets its hitting. I dont hunt with the IM as high not that it dont work i dont like the null and iron seems to want to hang. Everyone hunts a little different. As far as IM... if you ever hunted with a nob disc.... its just like slowly turning the knob disc out targets ..... and yes it nulls on any target you disc out. What you have to be aware of is it also will null on high EMI. I have mine set up so i can switch over in AM an listen occasionally to ensure im not getting to much EMI. These MLs are motion detectors but take very little movement unlike most of the faster recovery machines that needs that speed to for the filters to work properly.

Yeah, I tried AM for just a moment in my backyard, it was awful....lol. Might work good in certain situations, but for now I will stick with what works. I have'nt dwelled into ferrous much. Just now getting some time in to learn the sounds and visuals of conductive.

When I hunted in ground like you describe Dave, I hunted Ferrous mode, IM as low as I can stand and a small coil. My mind got to the point where I got used to the "iron drone" but when silver got under the coil, I knew it. I have to be in the right state of mind to hunt much of that, but a small coil is almost a "must have" if you hunt trashy ground very much.
