F70 IDing pull tabs/nickels

[mikie42]

I now have a CZ-5 which can't tell the difference between the a pull tab and a nickel. I dig ten+ tabs to one nickel. I am looking into buying a F70 and would like to have any info on how it ID's nickels/pull tabs.What #'s are displayed for nickels/pull tabs? What are your experiences with the F70 and the DD coil?

Don't know about the F70, but the with the F75 I can almost be 99% correct in telling the difference between a nickel and the soda can pull tab.
Now on the other hand, the beaver tails from beer cans will on occasion fool me into thinking it's a nickel.

One day that ring pull / nickel will be a gold ring with some ice in it, so why complain ! There is no perfect metal detector out on the market, if there was, we would all have it and be happy.

You may want to get the CZ3 or the omaga 8000 or the LTD if you are going to spend the money get your moneys worth. I did not care for the F70 nor the F5. I had the CZ 3 and it is slow in its responce to targets and trash the 5" coil can really speed it up. The 8000 is fast and the LTD is faster. All have realy good depth.

i would had to disagree with the last post ringpulls come up as 48 on the id i dont know with the nickel cos im from england. I do get fooled sometimes but thats the same with all detectors im well happy with the f70 its well deep and quick. Some people diss miss it before learning the machine properly.
I do agree with the other post when you cut ringpulls out you miss the gold and hammered coins.
If in doubt ask some other f70 owners

happy hunting

Actually, the cz series were pretty notorious nickel finders. I had two, the cz6 and cz3d and both were great on nickels. Since I've had the F 75 and F 75 LTD, these, like the F 70, I assume, are also great on nickels. Yep, like everyone else, certain tabs will fool both the machine and the user, but I know pretty well when there is a good chance of being fooled. Every so often one of those "good chance of being fooled" targets, though, ends of being a gold ring. Good luck with your decision. HH jim tn

I have owned the CZ5, CZ6, 6a, 7,7a CZSeries. All were awsome Nickle finders. In fact my nickle finds to this day go up when I use a CZ Detector.
I have not noticed a great deal of Nickle, or ring finds with the F75, or F75LTD..but I have noticed increased sensitivity and more overall finds with the F Series detectors. I have also noticed more Bottle cap (Rusted) Steel cap variety with the F series than I ever dug with the CZ series. This does not make the machine bad (F Series) it just tells me it is running a little different.......... it still finds nickles. It still finds Tabs. A lot of tabs fall in the reading of Nickles & Rings.I find lifting the coil off the ground on iffy nickle readings with the F75LTD works a bit for ID on nickles..Tabs drop off usually at about 4" above the ground. Nickles still hit solid and ID correctly.

Nice tip, thanks.

I have had a f-70 for over a year found a lot of coins very few nickels good detector BUT if you are a coin hunter get the Teknetics Omega I have had one for three weeks, I have already found as much silver all from the same area I have already detected with the f-70, in the three weeks as I have the 13 months with the f-70, I use the 11 DD coils on both its just as deep if not a little deeper than the f-70, 8-9" on a dime 10" on quarters, what I really like about these detector it DOES NOT loose depth in dry dirt until it rained yesterday the ground was like cement no depth lost at all took forever to dig the target ,I run the sens and gain wide open and I disc out everything but dimes and quarters and when you disc things out their is no spitting and spluttering no noise, and that what you will have with the f-70
so be prepared for that.Good luck. HH

Elton is right about tabs dropping off with the coil raised about 4" above the ground, where as nickels still hit and Id good. Personally, I am finding as many, if not a few more, nickels with the F 75 and LTD as I did with the cz's. 13 buffalo's and a v this year. However, I feel the cz's id nickels better at depth, those 5" and deeper, then do the F's. HH jim tn

My CZ ID's nickles pretty well. A few bent new type tabs ID as nickle, but the big offender is pencil eraser ferules.

On the F75LTD, nickles come in around 29 to 31, modern tabs at 33 to 34, the little bit older square tabs 36 to 37 and the beaver tail tabs 40 to 47, with a lot of them that either have the tail bent around the loop or no tail at all right at 46.

The only time my CZ's id'ed pulltabs as nickels it was easy to determine, the drop-off, as stated earlier. That and anytime I got a nickel read and a depth read of 4 inches I was very sure it was a beavertail. Same on both my CZ 5 and my CZ 7. Yes, the CZ's are awesome at hounding nickels. Almost every buff I ever dug read as a solid foil target unless it was in the 8 inch range or less than 2 inches in which case it read correctly. Pinpoint and depth reads were the key to id'ing them.

So far my F70 has proven itself in separating nickels from pulltabs easily. Exception will be war nickels as they read mid to upper 30's on the F70. I have had a problem with depth on the F70, no coin deeper that 8 inches has come into my pouches with it. It has excellent target id right up to 8 inches and that's it. After that I get no hint of coinage deeper than that and proved it out when fellow hunters with other machines compared deep signals with me. My deepest coin with the CZ's was an LC at 14 inches plus. Got Barbers a foot deep (quarters) and dimes slightly less with both my CZ5 and CZ7.

Got tired of waiting to see if there was some magic dirt spot where this rig could find a coin at 8 inches plus and ordered the 15 * 12 SEF coil, got it yesterday and will hitting the park in a few to try it out today. And oh yeah, I'll be cranking out the power on that thing too!

Stay tuned....

This statement is right on for the F70 as well. The beaver tails missing the loop fool me sometimes. Raising the coil off the ground a bit helps when you come across a good nickle tone.
