There's The Dream And Than There's The Reality


Recommended Posts

Fiddled with some settings, switched to 18 freq and went Gold Ring hunting.  Headed out to one of my favorite sites, a football field off a Middle School.     Since 2002 I've dug over a thousand clad coins, some silver rings, couple silver quarters and one Honker of a Gold Band out of there.  It has been dorment for quite a few years now, even the trash is scarce.    Anyways going out hoping for something Gold or at least break a Buck.   In between dead spots I started digging +07 ,bouncing up to +12 .....Started getting red clad nickels.   Nine nickels out of just 23 coins.    Did dig 2 pull tabs couple small pieces of alum between those numbers.     Every time I'd hit one of those nickel signals I would dream this gotta be a ring.      Nope Nickels all nine of them.     I believe +07 to +12 was caused by variances in depth, laying on its side and one was laying with a penny.     Also I think 18 freq, the numbers trend a little higher.    9 Nickels, $1.25 is actually a good hunt out of that field.   Well keep banging around nickels the Gold will turn up someday.    (Better hurry tho )

Dancer,

That is a lot of nickels, very good work on your part. Interesting that you note how the TID is skewed. I see this in a lot of coins that have been in the ground a while and are very discolored. I wondered if they might be close to iron that causes so much discoloration and TID change, but the TID can be quite a ways off on them.

I also notice that the harder I work the settings for unmasking ability, the more untrustworthy the numbers are, even at pretty shallow depth. It brings in a lot of those discolored coins though, so it is hard to know if it is the settings or the coins in proximity to trash that does it.

Seeing you hit those stained nickels with numbers out of range also makes me think it may not be the settings but possibly something to do with the coin in the matrix.  The TID is usually higher in 18kHz for sure, but not that much higher and not that variable. (Well, that is conventional thinking anyway.) The harder I work at unmasking the worse the TID becomes, you here show what you miss if you ignore out of range signals.  

Good report Dancer!

One thing I noticed using Mix, If I was getting a good bong sound with +07 to +12 , it was usually a nickel sometimes a corroded penny.    No luck with those numbers if there was any  - signs.      There are plenty of iron signals around, I just don't dig them.     There's rarely a fresh drop on this field. Today there was just one. Maybe a Crow dropped it.     Amazing that there are still that many nickels out there cause its getting real hard to crack 20 coins.

Despite the variance in TID, the Tarsacci is very very good at telling iron from everything else. (Except for the wrap around, but that is usually easy to spot.) The specificity in nonferrous can be poor, or at least appear so, but it is the iron unmasking that really sets this machine apart to my mind.

It is the ability to see through some iron and foils that matters to me, then ID the iron, then take a best guess on the rest. Pull tabs are still going to be a pain, and even more so when coins are not hitting where they should.

Yet you make finds. That is good work, since there are few recent drops you rely on unmasking to make your finds. This is exactly what I am attempting to learn. 

Keep talking.

Geezer,  heck sometimes the best way to understand your machine is to take a handful of coins. Mix them up with your common pieces of trash you run across.    Find a sand pit somewhere and fling them around.   Then hunt every coin out of there.    Stay away from digging the minus numbers see what happens.  After you find all the coins, find all the left over trash you left.    Of course have your machine ground balanced before hand.     Then head out to the Wild and see how you do.      Hope this helps, really I'm just a dig a good signal hunter but I do bite on those ( iffy signals ) more than enough.

The same for me. I try and learn something from every thing I dig. The trash is less now than before, those discolored coins more. The larger coil seems to help quite a bit, which is the opposite of what I would have thought.

That larger coil changes the TID numbers of coins, and the unmasking strategies skews them more, and picking out those on edge or masked coins creates a wider range of TID, and more I cannot think of right now, but, it is pulling those coins. In a lot of cases these are left behind because they are masked and missed. Or so I think.

I find a lot of quarters and dimes that look like those nickels. I expect to find those nickels, they hit like a pull tab. Dimes maybe fall in penny range sometimes, so some might not dig the penny signals, but quarters left intentionally is a little harder to see. Running through the trash digging these things is sort of fun all by itself, just for the challenge.

I have bit too often on iffy signals too. Less often now though. Good targets sound good and hold steady on a Tarsacci, no matter what the TID says. If it is not iron and hits good, I give it a serious look. Like you, I think anything that shows even intermittent negative numbers is likely to be junk. Just that saves a lot of digging.

The 12” coil seems to work far better on coins on edge. I know this because I use a pinpointer to locate them, then probe with a brass probe. RIngs and coins on edge will be hard to find with a brass probe, but the pinpointer says it is there. Often they are not even very deep and can be pulled out by fingers pinching, but coins on edge like crown caps tend to pinpoint off center of where they actually are and have funny signals. This may be partially responsible for the skewed TID, or maybe not, but they are sometimes surprisingly far away from usual TID and pin point location.

I get pickier all the time with the signals I dig. Of course I will miss some things that way, but I enjoy it more and spend less money on Chiropractors.
