The Nokta representative has said that the Nokta FORS Gold and Nokta FORS CoRe are basically the same detector. The FORS Gold was intended as a machine marketed for the prospecting market, with much of that being in third world countries. They wanted to make it clear the machine was intended for and capable of prospecting for gold and the best way to make that clear is in the name.
The FORS CoRe is literally aimed at the coin and relic market, and the name is derived from that - Coin & Relic.
The two detector are obviously different colors with different decals. But how about operationally? They currently are the same price so why chose one over the other?
The decision was made to simplify the FORS Gold by removing one operation mode - the Conductive Ground or COG mode. The COG mode expands the ground balance range to include not only mineralized ground but also the conductive salt range. We would best recognize this as a salt or beach mode. It is intended primarily for beach use however it may also very well have applications for alkali salt flat detecting and would be a good prospecting option to have. The FORS Gold can compensate for conductive salt ground by the more drastic measure of increasing the ID Mask setting until the signal from salt ground is eliminated. This works but employing ground balance as in the COnductive Ground mode is the preferred solution. For this one simple reason I recommend people buy the FORS CoRe instead of the FORS Gold since they are the same price at this time. Do note that by adjusting out the effects of conductive salt you also eliminate small gold signals since the two overlap. This is just the trade off you make to be able to operate a detector on conductive ground.
There is one other operational difference between the FORS CoRe and FORS Gold that I am aware of. From the manuals:
FORS CoRe TONE:
It allows you to change the audio frequency of the threshold and target warning tones according to your preference. There are 5 different audio frequencies ranging from treble to bass. Tone change does not affect the iron tone. It is active in the General Search, DI2 and COG modes. It is inactive in the Discrimination 3 (DI3) mode. It changes the audio frequency of the threshold sound in the General Search mode and the gold/non-ferrous metal sound in the DI2 and COG modes.
FORS Gold TONE:
It allows you to change the audio frequency of the threshold and target warning tones according to your preference. There are 5 different audio frequencies ranging from treble to bass. Tone change does not affect the iron tone. It is active in the General Search and Boost (BST) modes only. It is inactive in the Discrimination 3 mode. It changes the audio frequency of the threshold sound in the General Search mode and the gold/non-ferrous metal sound in the BST mode (TONE 02 -TONE 03 - TONE 04 - TONE 05).
NOTE: YOUR DEVICE WILL START IN BOOST MODE TONE 4. WHEN USING THE BOOST MODE, IF YOU CHANGE THE TONE SETTING OF THE DEVICE TO 1 (TONE 01) THE DEVICE WILL PRODUCE A SINGLE TONE FOR ALL METALS (GOLD, NON-FERROUS, FERROUS) ENABLING YOU TO HEAR SMALLER GOLD NUGGET SIGNALS MORE CLEARLY.
Note that DI2 (Discriminate, 2 Tones) on the FORS CoRe and BST (Boost) appear to be the same mode. It is possible BST has been tweaked for extra performance while prospecting but frankly I doubt it. The big difference is that it appears BST can be switched from a two tone discriminate mode to a single tone discriminate mode. This in effect changes the FORS Gold into a simple beep dig unit reminiscent of something like a single knob Tesoro. Just set the ID Mask to wherever you want and dig everything that beeps. By going extra low the division between ferrous and non-ferrous can be set better than on many other detectors - could be something here a person can apply to good advantage.
A lot of detectors if you set the discrimination control to zero there is still some built in ferrous rejection. They are not true "zero disc" units. Some are calibrated to give you a true zero disc setting, but the Nokta units go beyond this. The control incorporates not only the ferrous range but drops all the way down into the ground range itself, allowing for a very nice ability to fine tune the discrimination ferrous range from 0 - 40.
Nokta FORS VDI Chart
0 - 5 Hot Rocks
5 -25 Mineralized Ground
25 - 35 Salty and Alkali Soils
10 - 40 Ferrous Targets (Iron, nails)
40 - 50 Foil, Small Gold
56 - 58 US Nickel
82 - 83 Zinc Penny
84 - 86 US Dime
88 - 92 US Quarter
95 - 99 Hot Rocks
To sum up, at the same price I still think the FORS CoRe is the way to go. I have suggested to Nokta that they need to make the FORS Gold slightly less expensive than the CoRe in recognition of the Gold lacking a mode the CoRe includes for no extra charge.

I already have a Nokta FORS Gold and I just received a latest update Nokta FORS CoRe control box that will run on the same handle and coil assembly. This is really fantastic because back on October 11th I did a detailed review of the Nokta FORS Gold At that time I noted that I thought the control panel rocker switches were a problem as they would collect dirt and water. I also pointed out the left side mounted control panel would provide some hardship for left handed people.
Nokta responded by almost immediately announcing a special order version for left handed people! Shortly after that they announced the control switches would be upgraded. I have never in my decades of experience working with metal detector manufacturers seen anyone respond so quickly is addressing physical issues with a model already in production. There was nothing wrong or defective. It was just things that could be improved on. It was a rather stunning response and really made me sit up and pay attention to the company even more.
The bottom line is the LCD panel has been redesigned with a sealed touch pad. The power toggle has been replaced with one incorporating a rubber accordian type seal. The plastic cap covering the headphone jack has been replaced with a softer rubber version that seals better. The ground balance tracking rocker, which is in the downside facing protected end has been left as is, which is fine as this is a rarely operated switch anyway.
I also had noted that the coil scuff covers were paper thin and subject to splitting when removed and not likely to last in any case. Nokta sent a couple new scuff covers along with the control box. They are much thicker and either the extra thickness of use of a different plastic mix now has them feeling much tougher, comparable to other good scuff covers on the market.
This really should be nothing worth making a big deal out of except I think most people would agree we have all gotten pretty used to just generally being ignored. People make simple, sensible suggestions, and years go by with no change and no acknowledgement even of the suggestion. We have been told for ages changes like this just are not practical, so live with it. Well, looks like the game is about to change!
One last note while I was shooting photos - I thought I would point out that the Nokta FORS control box has a couple holes in the rod allowing the box to shift forward and back for better balance. Most people probably do not know that the actual box mount is also adjustable via a sliding section in the slot on top. Just loosen to allen screws, slide around until you have it where you want it, and tighten. At one point I thought there would be little need for me to have the FORS after the new Racer comes out but this ability to custom balance the unit when using the 15.5" x 13.5" coil is actually pretty important to me so looks like the FORS will be sticking around.
I'm new to this forum. So wanted to say hello to all members.
Ive been detecting for years, but been detecting for almost a year with nokta fors gold. Got out today to do some detecting at our property where we have found good gold before. There is many mounds in the ground sluicing areas that we never detected before. They are covered in several inches of pine needles and sticks. So we took a lawn rake and raked down to dirt to see what there was. I found 10 pcs of gold with fors gold at great depths. Also found 1 pc of gold at 8" with gpx 5000 and new camo coiltek mono elite. All in all was a good day. Gold weighed 1.9 dwt. Again wanted to say hello to the members and Steve
Im sure ill enjoy reading post on this forum. Seems pretty busy.

I don't post very much but I have been detecting 4 years now usually 2 to 3 times a week and recently bought one of the new Nokta Fors 10"x 5.5" coils and one of the ears broke after only using it in parks for 3 weeks etc, not in any gold fields which would put it to the test for quality.
I found that the ears are to thin and the holes are too close to the edge which is a weak point for it to break and that's what happen to my coil.
I wish Nokta made this coil with stronger coil ears with more meat around the holes like the other coils provided in the pro-package deals and made it epoxy filled and even if it had to be an open style coil to keep it light, so it could be used in water, as the way it is designed now it is buoyant in water and not suitable for use there.
Anyway I asked for my money back as I did not want a repeat of this coil breaking at the ears again and I would like to hear anyone elses experience with this coil braking at the ears, as I've had no problem with the other coils in the pro-package.
