Do most of you fellers' dig nickel/foil bounce hits?

[Hotcz70]

Just curious on what your take on this is.

I am very pressed for personal hunt time so I try to stick with deep silver coin hits. However...and this is a big however...I got another CZ to concentrate a lot on nickel hits that I pass on with my explorers.

I do realize that I will be missing some deep nickels or nickels on edge...or some gold rings...but do most of you dig all the nickel/foil bounces?

I plan on hunting with everything notched out below foil...and everything from foil on up notched in on my cz70Pro.

Depends on the area and what your after....sometimes in silver country just accept the last segment...One of the few machines I know of where high disc. cause liitle or no depth loss...

On a beach or perhaps a local park you bet I will dig everyone...matter of fact years ago produced a 16 diamond-14kt. turn of the century gold ring

If in an old area also will get the old shield-V-buffalo or deep Jefferson nickle also...

Matter of fact if I get a foil or nickle hit by itself just routine....but if I get the bounce...heart skips a beat....as found some nice targets this way...

Coin hunting, one of the things you may want to do is attack the target from multiple angles and if you get more of the high tone hit in proportion to the foil hit, and the high tone ID's as nickel, dig it.

Also, try sweeping the coil center over the target back and forth fast in 1- 2 inch lengths, as well as in an X pattern. A lot of times tricky foil will sound scratchy and the sound will break up a bit when bouncing, where older nickels and those with corrosion on them ( as well as some gold rings) that are fooling the unit will sound sharper with that sweep technique.

I was using this technique on the beach yesterday in the dry sand, and most all small foil and little foil balls that were bouncing foil/high tone nickel did sound scratchy while than some of the broken tabs in that same situation, as well as a few nickels, sounded much shaper. I made a mental note of the sound before digging the target and it worked pretty well when guessing what the target was going to be.

Check out Nasa Toms Fisher Intelligence on the CZ70 Pro, I havent read it in awhile, however he did a really good write up on the 70, (which he help design) and Im pretty sure he addresses your question regarding "bouncing".

I dig the bounce, but mostly to make sure I'm not missing gold and not as a focus on nickles.

 

[Dan-Pa.]

Dead nickle on any unit is a very low percentage for a gold ring while foil is the highest percentage whether it be a CZ or a wxy unit from another company but just something about that bounce
where the unit can't make up its mind really ups the odds. Fisher did a test years ago on a private collection of gold rings and 5 percent came in nickle but 33 percent came in foil.
Learned that years ago where a prominent member of Whites set up an XLT and deleted the nickle segment as he felt it wasn't worth digging all those nickles with his jewelry user set program.
Last but not least my wife has a nice gold mothers rings that will hit dead nickle on any unit so go figger as one never knows...

 

[Hotcz70]

then that I can greatly up the odds of digging a gold ring if I start digging most foil/nickel bounces?...without digging the dead on foil hits.

I just do not have the time...or knees to dig foil hits too...but would definitely be willing to try more nickel/foil bounces.

I got a cz again to compliment my explorers because I don't dig lower conductor hits...so I want to gain the most I can when trying to pick up some more nickels...and if I'm lucky enough..a gold ring...without digging too much junk.

However in newer park area the chances are it will not be foil or a Jefferson nickel but perhaps a beavertail, pull from a zipper, crushed end of a pencil metal that hold eraser or some small thig-a-ma-chig junk that is a small minority of the foil that is spread over the average park. Foil segment is quite large on a CZ meter from a tiny piece to a much larger one so theoretically for each individual dig of a foil to nickle bounce your odds on that one dig of it being a gold ring are greatly increased for each individual dig but on the whole someone who made many foil digs would get more gold rings and yes strain his back and knees making all these digs so for your situation dig the bouncers.
In an old area the foil nickle bounce to me would mean a V-Shield and some Buffalo and an extremely deep Jefferson Nickle with an occasional shotgun shell, 22 bullet and a thig-a-ma-chig or two with good odds you have a keeper old nickle..
Having used many units from different companies over the years some units have distinct audio variances but as far as gold rings there may be subtle differences with a CZ rel a gold ring and the junk that mimics it but too slight to make a difference to dig or not in most cases.
Have to admit an Explorer along with a CZ both find deep silver but the CZ on nickles and gold rings is the winner.
On a swimmer-sunbathing beach I would dig all and some actually notch out the coins on a digital CZ to concentrate on gold rings as one good gold ring with a nice stone might makeup for a week-month or even a season of digging coins.
Sorry for the long post but tried to be as clear as I could in laymans terms as I am a Detectorist not an English Major...
As an addendum anyone having a method to tell a gold ring from the junk that mimics it with a CZ and cares to share it would be appreciated. I do know the ring seems to hit harder but when you take into consideration of its depth, how its laying in the ground not enough to cut down the odds to dig or not as some of those mimic signals hit hard also especially that lead sinker which in weight is closer to the ring whereas a tab or piece of foil is much lighter..

If you are doing my favorite easy pickins' sites, them sidewalk tear ups, then you must dig those. Fatties and even some LC's will hit on the foil/tab bounce or the nickel/foil bounce in that matrix. The difference in deciding to dig or not is pinpointing. Solid coins/rings will PP accurately in the mix while phantoms due to the high mineralization will not PP and iron will usually PP offset from target signal indication.

 

[Dan-Pa.]

Every competent sidewalk outfit removes a bunch of dirt and fills it with an ash for drainage so follow the trucks for some good detecting..It appears to me water lines, piping, rebar etc. are affecting your signals and know fellas that have even raked the piles the trucks dumped...Sort of smile as the last time came up with two seated dimes and a large cent along with a newer silver roosie dime as the construction foreman shooed me off and I followed the trucks..Of course in your neck of the woods mineralization may add to the effect..Might try the 5 inch coil in these situations and good luck in your ventures...As far as high conductivity coins giving a foil to nickle bounce is beyond me as never came upon this in the last 20 years...with any detector...

Thanks Dan,
In the particular areas I was working last summer the sidewalks were indeed very old and the slag/ash matrix came from an old foundry in town many decades ago. I know this mix well as I've hit upon it in several spots near the old foundries in the past.

No piping or rebar existed and in the case of one 1862 IH, it was only 1" under a fine iron-rich ash layer. It rang up as round pull tab with an occasional bounce to the square tab. Sometimes there are a lot of nails and other junk in the matrix but not in the case of that one.

With my 5" coil on my CZ I got only two signals in this mix. Round pull tab and square tab. The round pull tab signals were all junk iron aggregates while the square tab signals were either copper, brass, coins or rings. But I'm still using that 5" coil that has never worked right on my CZ's, no matter which one I put it on.

The '38 LC I got out of one spot there bounced a little but ran from zinc down to square tab though it favored zinc. It was 6" deep on the edge of the sidewalk with no solid iron nearby. Using the pin point function to try to determine size at the indicated depth lead me to think it was a coin, though I thought perhaps a fattie or other IH at the time.

Comparably, my F70 also read most of the copper coins there in the range from 42-63 with the exception being copper mems that read in around 70-74.

I'd maintain that if you dig those mid range targets at the right depth, you may be surprised to find an IH or fattie popping out once in a while dependent on site, circumstance and matrix.

Living in an old coal town with an abandoned coal breaker I know the feeling about bad ground as almost impossible to hunt this area or local yards where they threw the ashes in the back yard. Reading between the lines I see you are doing well in similiar circumstances with extreme mineralization and a tip of the hat for your ability to pull out the coins considering the enviroment..

 

[Hotcz70]

increase my odds of digging that needle in a haystack gold ring....while not spending 1/2 my hunt time digging crap and further tearing up my knees

Sounds like the nickel/foil bounce will kill two birds with one stone...and although digging foil targets seems to be the obvious winner hands down for the best odds of finding said needle in a haystack...that's not my objective. My objective is to increase my odds while not losing too much of my hunt time...and keeping my knees somewhat intact...or at least what's left of them

Hey Bryce,
I tried the "double beep" method some years ago for a couple weeks thinking it would help ferret out the gold. Get a target indication in any of the mid/low mid range and determine the depth. We already know that the pinpoint and sweet spot will shrink dramatically if we lift the coil "X" number of inches off the ground.

So you have a target in the foil range, a solid target that pinpoints well. Now lift the coil until you are certain that s-l-o-w-l-y swinging the coil over it can cause that double beep as it hits on each side of the ring. ID may slip down a notch or up a notch, one of those unknowns until tested on a given target. This CAN work. It is however a HUGE time killer and you know what else, those pull tab rings give off the double beep if they don't have the beaver tails folded inside like so many others.

My results were less than spectacular. One gold ring, plated. Many other rounded objects including a few washers and pull tabs. So while I did cut down on the can slaw aspect I'd have probably gotten more gold rings digging everything in the range, that is if they are/were there.

That's why I satisfy the gold ring hunts with the playground/tot lot/beach equation. Easier digs mean quicker junk dissemination and more gold recovery for the time spent.

Chains are different altogether. You can distinguish them as the pinpoint sizing will demonstrate a narrow elongated object and even the silver ones will come up in the junk range so it's easier to hunt chains than rings in the park grounds.
