Help Me With My Nickels ????

[grumpy]

Morning Folks;
I got a new and problem I have not seen before. I use a Ex SE and have had it for a couple of years. The machine works great and finds Nickels like you would not believe ; always within just a hair of the same numbers and it is like a nickel magnet. I bought a New GT sov from Rick last year(thanks rick) and have been using it primarily the last few months. It is also a great little machine .
My problem is yesterday when I took out the SE to do a rodeo grounds the thing would not only read the thing wrong it would only pick up a nickel after serious wiggling over the coin. I could not get hits on even pull tabs in that area??? I leave in most pull tabs that are close to the nickel spot for that reason and jewls. I have used this custom program for ever even had it in the Ex II before this SE and it works great for me and now it wont pick up items that are programed in after sitting for a few months????? Is there a possible corosion problem in the innerts? or ? I put the machine in IM and it worked but still was not user friendly to nickels on the top of the ground but this has always been the SE problem it does not like coins on top of the ground I guess it figures thats cheating . Anyhow anyone have this happen or know any info Id appreciate it. Maybe it needs sent in and recalibrated??
Thanks
Grumpy

The problem might just be specific to that site, such as animal urine in the soil working like mineralization, combined with a lack of moisture to dilute it's effect, just might be a real difficult combo for the machine to deal with. I have sites like that where moisture, lack of, addition of fertilizer etc give me depth and success variances that go from surface only targets to 12 inches deep on a dime. At first I thought my SE was a fickle fish and then I bought a second SE and realized these weird happenings (which both machines would always share) could not be the machines themselves and were more a site, even day, specific problem that I would have to overcome with different coils and settings. Funny, how metal detecting is allot like fishing.

Thanks digitrich I tried three or four places and tried the GT when it would not work at each and it worked fine. We have definately had sites that were fickel and days with different weather is always a kick in the ass but this was wierder than that. I could bury a nickel or lay it on the ground at each place and the machine would just ignore it period. I thought for a minute it had been talking to my wife the way it ignored me but I would take out the Sov GT and it had just the same old numbers and noise so I could nt figure.
I called the guru at Minelab and he thought the battery could be the problem. I have two bats for the SE and I tried both that was my first clue. They both did it the same way but I am charging them as instructed to full charge and see if it still wants to lie to me and ignore my nickel and if so they want to see it for a check up : probally has to be recalibrated or a chip fixed.
Will hollar when we get the answer that fits and fixes it.
BY the way urine does throw fits in parks and things. If you find where a dog has been you get the pee signal BUT you lots of time find the money where they took out the bag from their pocket , or else they had their hands in their pockets wondering around looking the other way , either way sometimes those spots are good for some clad, just be careful where you bend down and put your knee
Again thanks for the help and thoughts on the problem. Really appreciate the feedback
Good Luck

Hi Grumpy,

One thing I would do is switch to iron mask so the whole area is not blacked out and then go over the nickle again and just see where it will read. If digital it should be ferrous at 10 or 11 and conductivity at 5 or 6. If using the smart find you will see the area where it will read, now switch back to your pattern by hitting the iron mask button again and see if that area is blacked out or not. If this area is blacked out or if you hit the X on the pulltabs in the select screen you will reject nickles.
