A little nickel help please....

[jbow]

First let me be the first to admit that I spread my time too thinly between detectors... but it is what it is, I like detectors as much as I like detecting so...

Yesterday I had about 45 minutes in a small front yard i've never hunted. I was trying out the new Omega-8000 I got. I dug a few pennies then I marked a couple of signals. One iffy and the other was a nickel. I had about 10 minutes before I had to leave and I got out the V3 to check those two marker targets. The iffy one turned out to be a small piece of canslaw... I don't remember how it read on the V3 but it was low 60s on the O8K. The nickel was reading 55/56 on the O8K, which is usually a nickel. On the V3 it read 15-19 on the searchscreen, on the analize screen it was all squiggly on the first try. I flipped the switch and checked analize again and it gave a great three hunp signal with a TID of 19... I checked it several more times and it was a nice three band hump everytime with blue on top. It was a narrow hump, which should have told me something but I would have dug it anyway at this point. It turned out to be a very small piece of aluminum can, about half the size of a small fingernail... very small. I was out of time and pretty well convinced it was a nickel.
I've been thinking of what I might have done to tell that it asn't a nickel without digging. All i've been able to think of is that if I had raised the coil, the point at which the target disappeared wouldn't have jived with the displayed depth... I think.

I was running in the stock C&J program and using the 8x6 SEF.

Any thoughts on this? I am going to spend more time with the V3. Going to send it in next week for the i !!!



Anyway... what about helping me to ID a nickel?

Hey Julien, There is a point to where you can only "split those hairs" so fine but all I can think of is...if those dang can tabs come in at 22/22.5 khz, then a slightly smaller piece of aluminum would 19. (Maybe an realistic expectation... but not a bad question.)

I hit a lot of can slaw..and it VDI pretty much like a nickle..it's just one of the things you have to accept. I dig them all, and it's rewarded me with a couple buffalo's and quite a few jeffersons My rule of thumb: VDI steady 19 dig it, VDI variable 17-21 (with some depth) dig it. When I'm bored and not finding anything else..dig all the iffies find a mix of can slaw and other pieces of pulltabs usually, but hidden in the bunch there's a buff or a V nickle somewhere. It helps to be optimistic.

I think i'll spend some time switching to 22.5 and 2.5 non-normalized when I get some of these targets. Maybe I should save some of these nickel imposters and bury them shallow with an assortment of nickels and try the different frequencies non-normalized... maybe there will be something different to notice but really, i'll be surprised. I can check in correlate too once I get a handfull of trash targets that read just like a nickel.
One of the worst nickel imposters is a folded over squaretab.

Thanks,

J

With only 15 hours of experience on my new V3I........... I run the Coin / jewelery mode with the gain /sensitivity turn way way way down like 4, so the VDI numbers don't bounce all over the world............I still get great depth and let the V3I do it's magic............. A hard 19 VDI would be either a nickel, or a half of a Pull - tab chopped up by the lawn mower. I have over 20 nickels with my 15 hours of the V3I.........it's a nickel magnet machine for sure.

And then there is the jewelry, in the last month or so I have dug two sold VDI 19

I'll go with Carl on this one. I've dug perfect 19's that weren't nickels and some bouncy ones that were. It's quicker for me to just dig them then spend a lot of time analyzing them. I've found my share of gold rings too. Rob

 

[Larry (IL)]

Surface nickels might read 19, and so will many other targets, can slaw, pop tops, Gold rings and the like. Nickels at depth will also read 14, 15, 16........... you get the idea. Don't get too hung up on the numbers Julien or you will miss a LOT of very nice finds.

Speaking of nickels...went to a huge park that has been pounded for 40 years by good equipment. Figured I'd try the out of the way bushes and....found a few Buffalos hiding in there! All solid 19's and all no more than two inches. (Ground just doesn't "build" under bushes does it?)
