Short Video - 1 Foot Deep Coin

Let me be a killjoy and say this was an iron coin and I'm not sure why I picked it up. It didn't sound good but it bounced enough for me to take a look. this is my deepest coin by 3" or so.

Any comments on how I could have picked this up are welcome. My only guess is that it is round iron and that sometimes fools us. Hey, but I dug a 1 foot coin! Now I know it will hit silver this deep ;-)

Congrats EMS,

What did the coin end up being? The park I hunt, I have picked up mid to late 1800's coins at 10"-11". What I have learned from this awesome site, is take in what they are saying and use what works for you. In my case "low and slow" is the key to my great finds. I also take the area I've hunted before and change the way I grid it. We have pounded this park to death and every hunt I still manage to pull a keeper or two. This is due to me changing my grid pattern and investigating every signal to it's utmost.

That is awesome surprise and I look forward to the details,

Moose
 
Wow !!!!
 
LOL, I actually forgot to look closer at the coin as I was bummed it was iron! I knew it wasn't an old coin. I just checked and it is a 1950 10 Cent Pfennig - barely barely visible, but clear enough. Even in proof shape it would only be worth .20 cents! eheheh

Interesting how far it had sunk. All the other deeper coins at 8"-9" and from the early 40's were zinc. I only found 2 or so aluminum/bronze coins at 8" and they hit better. In my book it says it is brass coated iron, but the brass is long gone as you can see. It was a bit of luck and chance me finding an iron coin. Was closer to water so maybe that is why it sunk so far? And maybe next time I get a deep silver? ;-)

Moose - I agree completely. I have covered most of this spot, sure I have missed lots of coins as it's big but my last few times through I had been hitting it a 45 degree angle to where I hit it before and I did pull a few missed coins, but clearly I got the easy ones and even most of the audibly deep ones where I had walked. I am starting to go much slower when I hunt as I know I have picked a lot of coins and it's going to be harder going but I also know there is a non iron 12" deep coin and I want to find that.

It is 14 degrees Fahrenheit so I'm not going hunting even if the ground isn't frozen beneath the snow but I think by now it is. Mostly on a video break...

Nice video!

Enjoy your 14 degrees, it was -26 F in here this morning...

OMG, I didn't know that was possible. I think a break is good.

Thanks,

Hi there 'earthy'. Well done on this one.

Great video and very informative for those yet to experience such a finds situation.

May I refer folks to the earlier post in which I tried to explain such a scenario.

I've had to tunnel under tree roots to achieve similar finds.....usually copper coins.

Now I carry a small 'pad saw' to do a little tree surgery if necessary !

Amazing depth on 1 foot: coin congratulations do you feel the NEL coil is better or deeper? Compared to the pro-coil and 10 x 12 SEF coil your thoughts please thank you phil.

The 12X13 is definitely deeper than the stock, but only by about 1.5" or so. It doesn't have the separation of the stock as well, that was very noticeable to me. The volume comes in louder and I think that is in part due to them not manufacturing it 100% to specs, but I could be wrong (Does the 10X12 SEF do that as well?) But, I would still use it if the trash level wasn't a concern. I have never used the 10X12 SEF but have the 6X8 SEF, which has great depth, really great.

I would choose the 12X13 NEL over the 10X12 SEF as I've just heard better things about it. But, I don't like the weight (of either). I'm going to go with that new 13" Detech coil. These are all good coils I'm sure, but the Detech is lighter than the Stock!

So why did u find an Iron coin with a ferrous number and conductive tone? Well simply put, what u are hearing is iron falsing. Lets say ur 1950's iron coin gets dropped and starts to sink. Over time, the iron particles detatch from the coin. This happens because when it rains or when water is present, it binds to the iron and forms rust(iron oxide) which then detatches from the coin creating a field of iron around the coin also known as a halo. Now u come along and pass ur coil over the halo and what happens? A signal is sent from the coil, hits the halo and is sent back. The speed at which it is sent back fools the detector into thinking its a conductive target based on the speed of the signal.

I have watched your videos, and the soil you have in that area plays a key role in what is happening. There seems to be alot of moisture in the ground.

What to do. Well, IMO, it's tricky for you because of your location(im guessing overseas), u could miss good finds however, if u have the time, then its really not an issue to dig whatever u like. If time is of the essence, then, if u get a signal like this, switch to open screen and if u get in the 30s with ur FE number, then pass.

Another option is TTF, if it hits both ways, then dig.

IMO, u have classic over-analyizing syndrome. I have it often, but u have to stop and think, how much time can I afford to this signal.

I hope some of this helps

Beyonder - Yes, I agree. The round iron coin was a prime false. (But it's still my deepest coin, albeit on a technicality ;-) ) I don't understand though when you talk about the "speed" of the signal fooling the detector (coupling with the halo)? Can you go on? I get the feeling that your 5 posts are not indicative of your experience level. :tongue:

And yes, the ground had actually flooded. The best depth though, seems to be a couple of days after a flooding, not quite as saturated.

I'm playing with TTF alot now. I do hope the next E-Trac allows quicker switching between modes and settings if you know what I'm getting at.

I've thought for a bit what you meant when you said I had overanalyzing syndrome and I can't come up with anything concrete, just some probabilities. Did you read I also have a V3i? :crylol:
Hey, these are educational videos and for me too! heheh I like the analyzing part as it's a part of the game for me. I know I could find more coins by just digging those better sounding signals but I really like the challenge and the video's make the discussions more interesting as we see what we're talking about and the new guys in particular seem to get a lot out of them. (And they're fun to do. And now it's winter food for me!)

I really like quick mask and it clearly shows iron but I don't trust it 100% yet as I've noticed the E-Trac with a fair amount of discrimination pulls coins that quick mask puts in the lower right corner at times. I think this is just cause my ground has larger iron and it might be masking? Once I dig another 100 iffy objects I think I'll be able to speak with better certainty on quick mask but so far, yes, the vast majority of the time objects in the lower right are iron.

Thanks for jumping in here. I enjoyed and learned from your comments,
Albert
 
yea I enjoy your videos.

Simply put:

When I say speed of the signal, it is the same as saying the time the pulse reaches the target and gets back. Just a little word economy on my part.

Or a little more in depth:

"If metal is present when the machine fires(a pulse/signal), a small current would flow in the metal, and the time for the voltage to drop to zero would be increased. These time differences were minute, but the improvement in electronics made it possible to measure them accurately and identify the presence of metal at a reasonable distance."

The measurement of this time difference determines not only the type of metal, but the depth. An "iron halo" is basically tiny bits of metal and the pulse(signal) takes about the same amount of time to register as say silver.
 
At least that is the way I understand it and a round target will hit deeper than a odd shaped item of similar weight and make up as a general rule regardless of metal type.
