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.
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.
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.[size=small]7[/size]X5.[size=small]2[/size]

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).
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.
