Nokta Fors CoRe the great unmasker:canadaflag:

I was out this morning on a piece of land I have done with every detector I have ever had. First a lowly Bounty Hunter, then a Fisher F44, then an F5 and last but not least my beloved Fisher F19. This piece of land is about the size of the typical suburban front yard and back yard combined. I didn't expect to find any real goodies but I went there merely to find out if the Nokta could pull an extra coin or two that the others had missed. I found a few old wheats, a religious pendant and a 1910 Canadian dime there in the past but that's about it for the good stuff. The place is moderately trashy but only in certain sectors. The dirt there moderate to high in minerals and it's a mixture of dark granular earth and small crushed rocks like gravel. It's very difficult to dig but the advantage is that no target is deep there (100 year old targets can be found at 3 inches maximum).

It started out badly with many rusty crown caps and about 30 minutes into the hunt, I began to ask myself why I had returned here again. I then found a very small and delicate gold cross. Things were looking up. Then a coin spill with 3 Canadian pennies from the 40's and 50's and a 1939 silver quarter. I was surprised because I'm sure I had done this area to death. I had actually found a wheat penny coin spill at this same spot. Not too far from there came one of my bucket list find: A 1904 liberty dime. I was in total shock. How could I have passed this thing ? It's not easy for us Canadians to find our own old silver quarters so this one really made my day. Then I found 2 silver dimes (a 1947 and a 1966) and a few wheat pennies ranging from 1914 to the 1950's. I found all those things in about 2 hours.

What can I say ? I'm flabbergasted... :) And I only did about half the yard !

The CoRe is not perfect (no detector is IMHO) but the more I get to use it, the more I like what it can do.

Settings were: DI3, gain at 90, discrimination at 39. I used the 7 X 11 coil because it's the only one I have for now. FC24 should be here any day.

Great hunt Mike. Congrats on the finds.---The only thing I would do different would be to lower the disc down to 10.-----But it doesn't look like you need any advice.---Maybe I should raise my disc to 39! :biggrin:

Mike congrats on the nice coin finds and the silver. The Fors CoRe will surprise you in what it can do.

I bet once you get your FC 24 coil, it will prob stay on most the time in your "trashier" areas. In the future, you might want to get the "oor" 4.7 x5 coil. That little coil in the more extreme trashy areas make the CoRe a deadly machine :smile:

I usually run my disc at 21, that is just enough to knock out nails and keep the machine pretty quiet in the iron. Back before I got a Racer 2, I ran the CoRe with a "oor" coil and in the extremely iron infested sites would run the disc at 10. Ya, I heard it all and would listen for a mid or high tone to pop out.....but boy would it unmask targets well.

Today with the Racer 2 I use the small coil on it, very low disc and set the Iron Audio Volume to just barely hear the low tone( iron ) and now use my CoRe to hunt more open areas or the fringe areas of older sites using a bigger coil like the 5.5 x10 or the FC 24 etc.

LOL I begged Nokta to make a Fors CoRe 2......leaving the machine exactly the same and just add the Iron audio volume and tone features and maybe expand the nonferrous range. Basically, do to the Fors CoRe what they did when they went from the Red Racer to Racer2. But no luck :cry: It would have been one heck of a machine. Most people say, well just get a Relic. It's not the same......in the very toughest of conditions the CoRe with the "oor" coil will still unmask better than a Relic with the 5" coil. And when wanting to use larger coils, the CoRe balances much nicer than a Racer. But I can keep hoping....maybe someday.

Thanks guys.

I usually set my disc at 20 in DI3 as standard. This is perfect for less trashy sites at least for me.Because I know that in that particular place valuable targets just don't sink I figured there was no use in hearing all the iron to get a little more depth perhaps. In trashy sites I have difficulty making sense of all the noise a detector can make and the CoRe sure can make a lot of noise. It slows me down to a crawl. By raising the discrimination to 39, it made the CoRe so much quieter. It allows me to hunt more effectively. I know some people would rather hear everything but I just can't concentrate. That's the reason why I always knock out iron on my F19 as well by setting volume at 10 (gets rid of the 1-40 ferrous zone altogether).

My thoughts on the CoRe exactly. I hesitated for a long time debating whether I should get a Relic or a CoRe. I wanted a midrange frequency machine but at the same time, I was used to the iron audio features of the F19 and those were on the Relic as well. The more expanded non ferrous range of the Relic was attractive as well. In the end I got the CoRe because I favored the 15 kHz frequency and because I could get a better deal on it. Time will tell if i made the right choice but so far I'm impressed with the detector. The more I use it, the more goodies I find and the less I think about not having iron audio and an expanded non ferrous range. It seems to do very well the way it is. If it ain't broke don't fix it as they say.

I might get the small round coil at some point. I might be surprised at what can be found in very trashy sites that I have tried with the 7 X 11.

the White's, Teknetics and Minelab models I had at the time, and it did so in a remarkably brief period of time, too! It was partly the comfortable weight and excellent balance, partly the simplicity and ease of adjustment complemented by the general purpose performance, and in that mix was the splendid way in worked for me at unmasking desired targets in and amongst dense iron nail littered sites. :thumbup:

I've been enjoying this sport for over 52 years now and while I do put in as much time as I possibly can Coin & Jewelry Hunting any urban site when I get the chance, I've concentrated my main efforts on older sites that abound in ferrous trash for 48 of those years. Most especially since we got decent detectors to handle very iron littered sites in mid-'73. I have used many, many detectors that operate in that mid-frequency range of 10 kHz to 15 kHz and the CoRe was the first very versatile model that ever beat the competition and virtually tired my favored Tesoro's when it came to iron handling abilities. I have used mine for over 2 years and 8 months now, and it never lets me down with how well it can unmask desired finds in dense debris. :detecting:

I made this statement to the good folks at Nokta after I evaluated the pending FORS Relic in early last year. As I describe, I hunt a lot of heavily iron littered sites and the new Relic, operating at 19 kHz, easily out-performed other makes and models I have owned, used and compared it against that also operate in the higher 17 kHz to 20 kHz frequency range. That included the Lobo ST, Tejón and F19 from other makers, and also when up against models in the mid-range of 10 kHz to 15 kHz, with the exception of the CoRe.

Both models unmask good targets in dense ferrous debris when using their smaller-size search coils, and they each have some slight advantages in their favor. In nasty sites with a lot of rusty tin, the Relic gets grabbed before the CoRe, but a lot is more of a gut feeling of what I think might work and how I feel about the type and amount of discarded junk that needs to be dealt with. But just as dependable as the CoRe is to not get bumped by the release of the Relic, both the CoRe and Relic can still hold-their-own since the release of the new Nokta Impact.

I know some people might only want to afford one detector, and if they want a lot of flexibility and versatility in one feature-packed device they can't go wrong with the Impact! Another model that also has a very nice assortment of search coils available, to include the new 7" Concentric, which really gives it some different performance capability and the Impact, Relic and CoRe all can complement each other quite well to add versatility to my Regular-Use Detector Team and there is absolutely no way I would want to part with any of them. Each device provides me with excellent general-purpose performance and all of them can unmask desired targets in trashy conditions very well.

Why did the Relic and Impact impress me so much? To be honest, it was partly because they had to do really well when I worked them afield in the nail plagued older sites I frequently hunt when going up against the FORS CoRe with the small 'OOR' DD coil. The CoRe, as well as the Relic and Impact, can work well with their standard 7X11 DD for average search needs, but when the amount of trash, especially dense ferrous debris, calls for a change to a smaller-size coil to better handle the conditions, there are not many detectors that can keep up with the CoRe and small 4.7X5.2 Out-Of-Round DD coil.

Mike, my CoRe units are saved to turn on at a Sensitivity of '95' in the Di2 two-tone mode, and at '99' in the Di3 three-tone mode. I can adjust them down if I find them to be a bit unstable.

As for the ID Mask, aka Discrimination, my preference is to hear iron nails, along with most other ferrous junk, and I search at my saved setting of '10.' If I get into a lot of nails to the point where it is just too annoying to listen to, I can switch to a relic or Impact that feature the Iron Audio Volume adjustment ... or ... I just bump my CoRe ID Mask setting to '20' or '21' and reject the iron nail response. There are a few times, not many but a few, when I use a Discrimination setting of '39' or '40' to reject most ferrous trash but ti doesn't happen all that often. I probably search with a setting of '10' about 90% of the time.

As for noisy operation, I find the Di3 three-tone mode to be the one I use when Coin Hunting in a dense urban littered site such as around a frequently used picnic site. It is my mode-of-choice when working a smaller coil in a ghost town, homestead or other location where there is an ample amount of nails and other iron discards but also when I have to deal with a lot of rusty tin. Di3 does a very good job for me to audibly classify tin and similar sheet iron type trash. I use a slow and methodical sweep speed and I think that helps to reduce some amount of noisy operation, especially in a very littered location.

I'll be heading out for some chores in about two hours, and as daylight breaks I hope to also get in a bit of detecting. Today is going to be a FORS CoRe day when I get started. I have a CoRe, relic, Impact and a Tesoro loaded in my Tahoe, but enjoy starting out with the very proven CoRe because I can find stuff, but also get a feel of what a site might provide in the way of challenges. As the day progresses I might also work my Relic and/or Impact as all three models serve me well, but there's just something I really like about my CoRe units.

Best of success to you as you continue to use and learn your FORS CoRe. It looks like you're doing well on the small site you described and there just might be another silver coin lurking there for you to find. Oh, don't forget to consider adding the little 'OOR' DD coil to your accessory gear, either. The new FC24 coil will impress you, I am sure, but once you slowly and methodically work a small 'OOR' in and around trash and brush and rubble you'll really be surprised by the performance. I know I was.

Thanks Monte. I'm getting the OOR coil. That coil will exercise my patience because I often move faster than I probably should and patience is not my forte but I think I have a few places that could really use a coil like that. I'm talking massive trash. I like to pull a single good target from a site where a number of people have told me was hunted out.

By the way, I bought the Killer B's Optima headphones in camo. They should be here soon.
