Interesting thread on Herschbach on the GR - in it "cabin fever" posted some interesting stuff on rings. Hope nobody minds my cross posting - the link follows.

"The amount of tiny pieces of foil is disturbing. This detector is extremely sensitive!

Even though the Gold Racer is hyper sensitive to foil I have hope it still could be a good
gold ring hunter.
What I noticed is that all these tiny foil signals were in the upper 30s low 40s and the
numbers jumped all over the place.
Doing some air testing at home I noticed the Racer locks on to rings hard!
You can't shake the number.
Several gold lady's rings from thin 10k to med. 14k with diamonds each had their own
number. 48 50 51. Different numbers for each ring of course but it locks on hard to
those numbers. "

But diamond-stud earrings, pendents, charms, hoop earrings etc........ will look quite a bit like tiny pieces of foil.
A closed-loop gold ring will give reasonably solid/repeatable ID's.

That is one of the great nuances/traits of the Turkish machines. They lock on extremely well to good metal no matter what the shape.

That was my post.
My CTX 3030 locks pretty good on rings but the Gold Racer REALLY laches on.
You can't shake the number until you get to the very tip of the coil or are almost scraping the ring
And even then it will only waver one number.
One thing to remember is these are tests run on my floor.
Add in some bad ground, depth, rings on edge etc. who knows what will happen.
The one thing I do know is that my Gold Racer holds on to gold ring ID #s better than my CTX.
I did do in ground testing on pieces of can slaw and foil with both machines.
When the CTX did lock on to a trash target the Gold Racer numbers bounced all over.
Only time will tell but I'm hoping for an edge on rings with the Gold Racer.
Aren't we all?

Thanks CF - hope you don't mind my cross posting, but I think any info on shape recognition is interesting.

Its a pure gold machine...

Nuggets are porous and weird shaped so it will nail them just like the foil hits..At least the nuggets I have ...Its all over them...and yes it loves foil especially TONAL wise...

That's a good thing,,

Now round does really lock the I.D. up well..

From gold coin testing this thing ought to be the APEX unit the way it just ignites a Dollar gold coin......

BUT!!!!!in dense iron its going to be a Bear to unlock a gold coin with this unit...I would go back to FG+ for that task ...

But in more scattered iron and I find at the edges of the house sites if theres a Gold coin its coming out of the dirt...or any type round low conductor for that matter...

Ill be truthful.. This has been one of the most Tedious machines I've used in iron...you will take a beating in iron with it...and find little...FOR NOW...I will keep at it ..

Pull out of the iron till its scattered and it will lite up targets ,,,I dont know of any machine that will match it on SOME of the targets it sees

SO what we have is a Serious gold unit,,,that is on a Freq that is not the kindest to trash...Yet its the only unit we have that is unique enough to let it do double duty...


Right now I feel the FG+is a superb relic hunter and surely a great nugget hunter....the Racer Gold SHOULD be a Superb Gold nugget unit and a GREAT Jewelry hunter if you can dig some trash...Im sure it will get the stuff the others leave behind ..unless its a 71 Khz GB,But Ill leave that to the Je hunters to sort out...

Im after relics and STILL at the moment its a NICHE Unit for relics...Maybe the best there is at the NICHE of nabbing the lowest of conductors at decent depth.. but its site dependent iron contamination wise..

My woods hunting starts this week.. as Deer season ended today...So I can start to really see what it can do in some of my better sites that aren't modern trash littered...


It will wear you out on a construction site by the way...LOL...

What I have found is if it can get a clean read on a target it really can talk to you and will lite up stuff few if any can or will.Smaller stuff at good depth for that size and of low conductance.......if its co located in iron it will not talk to you like say the Racer or Core or even the FG+..

Heck I like running it..I like the challenge...I'm just waiting for the Moment to hit me when it SHOWS OFF and I find out what it can REALLY do...

One of the more if not most challenging machines Ive ever used in iron...I LIKE IT !!New Challenge..

Still hoping for a 5 inch Concentric...That might be the ticket for dense iron work..the 5 DD right now is a godsend but a Con. of same size MIGHT be the unlocker component..

Don't mind at all. I can't wait to get feed back from others.
It was something that really jumped out at me when I was doing my testing.
When I first started using my CTX I was hoping to use its ability to lock on to rings
While park hunting but it turns out that it will also lock on to a lot foil can slaw and pull tabs too.

I did some more testing tonight. I think it's a round thing but type of metal might come in to play too.
I'm not smart enough to know that and will leave to other members here.

I tested all different shapes and types of pull tabs as well as foil.
The rounder it is the more it locks on but I still could not get any foil or pull tabs to lock on like a gold ring.
The dreaded beaver tail pull tab where the tab is bent up in the center of the ring always fools my CTX and was pretty tight
On the Gold Racer but still bounced by one number off and on.
I smashed a wad of foil flat and round to the size of a nickel and it also bounced, again by one number.

I tested 4 lady's rings 10 and 14k. 2 of the heavier rings have diamonds..
They would not come off there ID number. No bounce, not even one number.
Bryan

Hey Bryan it may just turn out to be a Ring hunter extreme..

Especially the Thin ones..

Always good when something makes you take notice right off the bat...LIke the rings Vs Foil you have discovered I.D. Wise..

Good intelligent awareness you have..


One thing for sure is if its round its out of the ground..


Thank's for bringing the post over Rick!

Nugget hunting is what I bought the Gold Racer for and it is HOT on small gold in my testing
for sure.
It's a very smooth running detector in All Metal so far. Hope this holds true when I get it out in
to some tough ground in gold country.
If the Gold Racer ends up being a decent gold ring cherry picker that will just be a bonus.

Now if the snow would melt I can get out and put this thing to work!
Bryan

By the way. Gold Ring ID numbers do not lock up in All Metal. The number bounce around quite a bit.
Most of my Ring vs foil testing has been in the disc 2 mode.
Bryan

Hope the snow melts soon for ya ..

With this weird weather you never know...

Are there any comments you can share from your testing about the GR's susceptibility to EMI?

Very limited time on the Gold Racer but so far very quiet.
In fact better behaved than my CTX.

I had one skinny strip of grass with no snow out in front of an elementary school to work with.
Pretty busy area with a stop light and power lines running right down the street next to me.
The CTX can usually be tamed pretty good with noise canceling which I had to do 2 times.
Still a little chatty after noise cancelling
No EMI issues with the Gold Racer at all. Even with both detectors on at the same time.

I want to state that I have very little time on this detector so I want to be careful talking about it, but so far I really like
what I see, hear, and feel. It is a very unique detector. I have never ran anything like it.
I have a feeling it might be a little special.
Time will tell.
