Silver in the nulled out lot (literal silence)

JimmyCT

Well-known member
So tonight (before I got home and realized my poor rubber boot broke on my meter) I was at my local around-the-corner park. In the past I have hunted a hill that leads to where I went hunting tonight but never hit way up towards the middle of this lot. So I start out with a constant threshold and then all of a sudden it disappeared (completely) so I slowed down to extreme snail slow and still nothing. I raised the coil and my threshold returns. I starting scanning again and instant solid null. hmmm If I went any slower my coil wouldn't be moving lol. I eventually make this path towards the road ( found a penny through all the null) I am now wondering if there is something wrong with my machine. I walk across the road and start scanning along the roadside. Everything is fine over on this side with a light steady threshold humming away. So now that I know nothing is wrong, I cross back over and start swinging again. Right off the bat I (right through the null and all) I hit a nice high pitch / 180. I dig down and pull out a wheat. I get up and rescan the area and it is still sounding off a high pitch. So now I start thinking to myself, " please let it be silver" lol. Sure enough I dig again and out pops a 1943 mercury dime. "nice" I am thinking. I the find one more wheat in the area with some clad on my way out towards the wood path. ( the two wheats were 1940 & 1945)

See in the picture (on the newspaper), the big piece of iron? The ground was plastered with it. I can't even imagine how other conventional detectors were able to pull coins out of this area with this amount of iron. I am baffled and stumped for an answer. The GT did come up for air (threshold) but 95% of the time it was a quiet solid null throughout. Never have I experienced such a thing. I did learn one thing: The GT can be in a complete solid null with no threshold (even though there should be one )while scanning and still sound off on coins. I am really, really impressed.

Thanks for reading.
 
bee u tifull, silver coin Jim but just think how many silver coins are masked out by all that Iron I bet if you dug out the nulls you would find silver, . I have been prakticing pinponting with just the null, and i got one good target to come thru after removing iron I found i was getting some sippy high tones around the silent null the spot where its silent is were the nail or Iron is but out from the edges i would get funny high tones that were way off the mark still lots to learn You wure are getting lots of silver its very rare for me but if this field opens up I expect some real goodies
 
How high were you running the sensitivity? I find that if I put it in auto the silencing of the threshold combined with slower sweep helps out really well. I was experiencing this last night. I was out scanning a new area. I thought it was a combination of iron and lousy dirt myself. Plus it is just a dry as can be here.

Jim the Sov will null/go silent over any object that is disced out. If you turn your disc up high enough it will null on pull tabs. Its not just iron. Any chance your disc was turned up all the way?

Sounds like a good site to experiment with different settings and see what works best.

Glad to see you got some silver with the Sov:thumbup:
 
Thanks Gunnar. There is way too much iron in this place to start digging it out. I feel I work hard for the little amounts of silver I do find. These local parks have been hit relatively hard over the years. I am certainly not saying they are empty because they are obviously not.
They have been hit quick and hard for the cherry finds. I know with some patients the deeper finds and out-of-way areas that detectorists didn't bother to think to do ( or didn't want to do because they thought or was told it was cleaned out) will hold my goodies. I am taking a small break until this heat wave passes us by. HH - Jim

Hi Goodmore,

I had it in auto sens for the duration. There was no possible way I could of run it in manual. I was barely moving the coil in auto and still no threshold. The slightest movement of the coil it nulled. Yes, we have extreme dryness here in CT too. The dirt is like powder after breaking up the clumps of dirt.

Hey Neil,

Both my disc and notch were off. Yes, I was thinking this last night while I was there -this place is going to be a test bed for experimenting. HH - Jim

Hey Straker,

The only coil I use is the 10" stock coil. I had a 5" coil but rarely ever used it so I sold it. - Jim

What coil were you using,Jim? Do you use any small coils?

Hey Goodmore...is this your dog? :crylol:
 
Good information Jim!!
I have read that the Sovereign will still detect coins while in a null, but you just have to slow down.
I believe Neil stated this in a past posting he made in a reply to someone.. maybe me.
I have not personally experienced this myself yet, but due to your post, I may no worry so much about the threshold nulling at sites that I know should be holding some good finds.
Thanks for posting,
Felix
 
You are very welcome.
 
Wow i learned a heck of a lot from reading this topic! I'll try the many tricks mentioned here and will let you know how I go

Cheers

Try hunting in the lowest or near lowest manual setting and also Auto. Some times one will provide a better threshold over the other based on the ground matrix. Yep, move the coil really slow. I would have iron mask ON to help pull tones out of the iron too.

The best option would be to use a 5" or the Minelab 8" (7 & 1/4") coils to really sniff out the coins in that iron.
 
do a test garden and you will see even in a null (unstable - hot) you will pick up items.. Obviosuly the slower you go the more pronounced the signal will be. Ive been on roman sites that are exactly like you describe. I could only run in auto..
 
Hi Critterhunter,
I only own the 10" minelab coil. Will the 2" difference between the 10" & 8" minelab coil make that much of a "pronounced" difference in diciphering signals in all this iron? - Jim

Yes, I am running with the ironmask on and have it in auto sens

The Minelab 8" coil is I think really 7 & 1/4" in size. I know my friend's on his Excal looks like a hockey puck. I'm sure it would make a big difference in providing some room between the nulls. Another trick would be to raise the coil off the ground a good bit as that should narrow down the size of the detection field and give less nulling. Even DD coil signals get smaller as they get further away from the coil like a concentric.

You know, you might even try flipping the coil straight up and hunting that way if the iron is that bad. I know some recommend PPing by doing that with a large coil like the WOT.

I'd love to see what my S-5 coil could do there. Talk about a tiny coil.
 
Hi Critterhunter,
I don't understand please explain further. If I flip the coil straight up,(90 degrees? ) there would be no detection field going into the ground. ( maybe I am wrong) I am not sure I understand either about how one would pinpoint. The ground is really this horrible. I never ran into such a huge null basically through my whole hunt. That chunk of iron in my pic covers the ground. Not quite sure why this area is completely plastered with it. Yes, someone else told me the coil is 7 1/4" too. So it must be. Well, if I see a good deal on one I might just jump on it.
 
Just don't get the old BBS version which is heavy as a boat anchor.

Flipping the coil 90 degrees is just a wacky thought. Not sure if that would work or not but I know some WOT users do that to PP a target so perhaps it would work. Forget that...I'd try going real low in manual to compare to Auto and swing real real slow. Also might try raising the coil off the ground 3 to 5" to narrow the field down a bit.

At the very least in that kind of iron mess make sure you overlap your swings by like 2/3rds. There might only be one spot where a coin sounds off and an inch either direction you just get a null. Gridding the area from two directions would be a good idea too.
 
Thanks for telling me about the BBS boat anchor lol and suggestions in the heavy iron. - Jim
