Dear friends, my name is Carlos, after take some time reading and learning in this excellent forum which you speak, I decided to register to participate and make a query.
Sorry for the translation but either speak your language, I only speak Spanish.
I have a GPX5000 with 2 coils of 11 "that comes standard, plus one 10" -5 "elliptical.
The problem is that I can not make work the mode detector relic coin, I always respond with a loud earth.
Regulating or gain rx, no stability and other parameters make it work with any of the 3 coils.
Could any of you if you please, tell me if the same thing happens or how it could make it work?
I greet you and thank you for your attention. Very Happy
Carlos

I think you'll find that the "Coin/Relic" mode also turns the ground balance off, hence is only suitable for benign soils. If you're trying to use this mode on mineralised ground it will squeal every time you get the coil near the soil. Cheers.

Greetings Carlos,

If you are searching for relics with the 5000 and the ground is noisey use enhance with a mono coil.

It will be difficult if there are lots of metal targets in the ground but it will pick up deep targets which is good.

Coins, silver and bronze will give you slightly different sounds compared to iron in many cases.

Others members with more experience may give better advice??

The 5000 is not the best relic detector unless the ground is very quite or you need to detect very deep small targets.

Dear Qld Sandy and tribute, thank you for your answers.
Do any of you or someone successfully tested coin-relic mode, or simply not possible to use it?
I tested on several types of terrain without success, to bring the coil to the ground always gives a signal as if metal. I think that this mode can not be used, at least with my gpx5000.
It is a shame because it seems to look very deep and I would like to use it.
Greetings.
Carlos

G'day Carlos

There are better coin/relic machines eg: (Minelab E-TRAC) that are dedicated to the task than the GPX5000, the GPX5000 is a very capable machine on the gold fields or even for hunting coins and relics if used correctly.

My suggestion is to forget the coin/relic setting on the GPX5000 and just use it in either normal or enhance or even finegold mode, you will get all the performance you need.

If your ground is even slightly mineralized the coin/relic mode will give you grief, where as the other more standard modes won't and it will still find coins or relics just the same as it will find gold.

I dont know why Minelab put this feature on the machine when it is as near to useless as you can get (IMO) except on a few spots of ground where it is about as mineralized as air.

Just stick with normal or enhance or finegold modes and adujust the other settings somewhere around the (FP) factory presets to start of with and then you can finetune the machine from there to suit the job you are trying to do.

Ok. Thanks davsgold.
This was what I wanted to know if all GPX5000 have that problem with the way coin relic or mine had some trouble.
I can see what he tells me that this detector is not suitable for that mode and it is better not to use it.
Perhaps with a large coil does not have much sensitivity to the land and can use, I have to prove it.
I have thought about buying a larger coil for gold deep, it might work well with coin-relic mode.
¿What do you recommend, mono or double D, and that particular coil size or think is better?
Here is a little gold and there to look deeper, if there are other valuable things. rabbit Wink
Thanks again for your attention

G'day Carlos

I am pleased that you find that helpful.

Even with a bigger coil you will still find that the coin/relic mode will not be much good at all. If the ground you are trying to use it on has any mineralization it will cause the coin/relic mode to be unusable, as a bigger coil is just taking a bigger sample of the ground, even though the bigger coil is not as sensetive as a small coil.

I prefer the mono coils on the GPX model machines and use it in the "ENHANCE" mode most of the time. If I am using a Double D coil I use it in "NORMAL" Mode.

Mostly in an area where ferrous junk (iron and tins) are everywhere the GPX5000 or 4500 for that matter can be very frustrating because they are very sensetive and can pick up junk signals from ferrous objects from a long distance, so you need to be very patient and slowly go through the area removing the rubbish targets and then re detect listening for the better deeper soft targets.

Because there are people in the world who can and do use the Coin/Relic mode because mineralisation is not an issue (areas in Europe where the soils are derived from Glacial action (soils are known as Loess type soils which are made up of large particles)).

Short clip of interview with Bruce Candy (designer of the GPX detectors) on the Coin/Relic Mode




The GPX series detectors are about giving operators world wide a variety of shovels for different holes, some of those shovels you will never use but it is nice to know the detector is capable of satisfy a very large range of people who do have a need for different shovels.

Well then JP why not explain to Carlos how to use it then, he's not from Aus and he may or may not have the type of soils you describe, but in any case he is having trouble and you may well be able to help him.

Post  davsgold on Fri Feb 11, 2011 7:48 pm

JP none of those links helps to explain how to effectivly use the coin/relic setting on the GPX5000

As far as I could see they were using the fine gold timing or enhance and on the last link using a DD in normal and with discrimination.

Gordon Heritage dosn't seem to mention much about coin/relic, but says in part "For low mineralised soils there are several dedicated timings. Sharp timing is probably the best for finding deep small hammered coins. Coin/Relic is great for finding larger items like cannonballs on old battle fields, but isn’t the best choice for finding thin section finds like hammered coins. Coin/Relic is the most powerful timing, but doesn’t handle mineralisation like other timings, so can be very difficult to stabilise on all but the most benign soils. Normal timing is also a good choice and my personal favourite."

Your question JP to Gordons article doesn't ask about coin/relic either but more on the other timings that we already know about and use.

I expect that "there are people in the world who can and do use the Coin/Relic mode"

Carlos is one of these people that was trying to use the coin/relic mode and was having no success, so you should be able to better than anyone else explain to him how to use this mode, or if it won't work on his ground what may be better.

I still say that if the coin/relic mode is not suited to a particular ground type it is as good as useless, and you have to try some of the other modes like finegold enhance or normal, as these suit a far wider range of soil types.

Dave seriously, "stop trying to teach your mother how to suck eggs". It's pretty obvious the OP is working in ground that is not conducive to Coin/Relic, hence the links to material that will hopefully help him achieve his ends! My first post on this thread was in reference your obviously critical remarks about Coin/Relic in general which I feel are just plain wrong!!

Contrary to your opinion there are places in the world were Coin/Relic will perform wonders, one of which is on the beach, but of course you don't detect there so of course that is also a wasted option on a detector you obviously don't intend to own. scratch

Thank you all for your help friends.
I see how currencies relic is too sensitive to mineralized soil. This is what I wanted to know, that my GPX5000 has no problem.
Monolop buy a larger coil to have more depth and will use other modes stable detector.
I have prepared at home a little place for testing, with a PVC pipe buried in diagonal and depth scale. They'll try all the modes and settings as well as the answers to all types of metals.
Jonathan Porter, thanks for those links, there is much important information in them, read that always learning new things.
I understand you have said, to buy a GPX5000 if I just go in search of relics, as for gold, there is a river near my house have been removed several tons of gold and those that still remain to be discovered.
The relic as currency is for a search point where I need more depth, just that.
This detector GPX5000 is far superior to my old but appreciated xplorer XS and my good Rex Land Kraft , this is very deep but very unstable.

Thanks to all friends, I send a greeting from . the area I live

Carlos for gold nugget detecting in mineralised areas try these settings, using the supplied 11" Monoloop Commader coil and supplied headphones.

Main Menu

Volume Limit 12
GB Type General
Special Fine Gold
Manual Tune 80 - 130
General Search Mode
Motion Slow
RX Gain 11
Audio Normal
Audio Tone 50 to 60
Stabilizer 10
Signal 19
Target Volume 8
Response Normal
Tracking Medium
Iron Reject OFF

Suggested switch positions on coil lead connection end of detector.

Search Mode General
Soil Timings Special or Enhance (if you select Special then the Fine Gold timing of the Special menu option is selected)
Coil/RX Mono
Ground Balance Fixed (use the Quick Trak button on the handle to manually Ground Balance the detector)

Notes: The reason the detector was unstable in your environment is because by the sound of things it is a gold field, gold fields are generally mineralised which means your detector needs to have effective Ground Balance to handle the ground conditions, something that the Coin/Relic timings cannot do. However the GPX 5000 is still a very powerful detector so don;t be afraid to use the other timings on the detector to see which one of them will handle the mineralisation specific to your area.

If the mineralisation is not too severe then you can use another timing such as Normal or Sensitive Extra or even Sharp, all these timings can be used in the tracking mode if required.

Good luck in your search,

Regards

Jonathan Porter

Dear Jonathan Porter appreciate your help.
I will have this configuration in mind when you go in search of gold.
Until spring or summer will not go out looking for gold in the river water carries a lot of poker now and it is not possible.
I have heard that there is much gold in the old channels, but is gold millimeter
and that can not be detected with GPX5000, only to (panning).
Also tell you that in this country (Spain), are not let out with a listener and treat us like criminals, so we hide from the police ... lucky you are free to practice their hobby.
I also practice trial with motorcicle, and is also prohibited, as well, escape from the police for practicing a healthy sport ...
For my part I can stop answering this question, with the help they have given me my doubts have been as a result.
When you find some gold I will give a picture of the discovery.
Thank you all for your attention. Wink
