GPX 5000 Mono Coil Setting

Good Evening All

I have a new GPX 5000 and have managed to set the DD commander coil and get the machine to hit the Gold Target.
How ever anything deeper than 6 to 8 inches the target is fairly soft and need to hear very carefully.
The soil is very mineralised . I swapped then to the elliptical Mono coil that comes with the machine and yeah she is a bit loader on the target but getting a lot of ground Noice when I'm sweeping that almost sound like a target . What is the best setting for a Mono coil on heavy mineralised ground?

Also what is your thoughts on the Nugget Finder Evo 19" coil is there any other settings i need to take care of.

Hi Dennis, I had a 5 and they are a very good machine, my advice from my own experience is: get a 12 inch Nuggetfinder evolution coil, it's light and I found plenty of really small pieces and some bigger pieces at depth, when you have your settings right the detector runs quiet and you will definitely hear the targets, I've been back over the patches I found with the 5000 using a 7 and a 6 and have only found a few small pieces which proves how good the 5000 is, good luck with it.

Great info Dave. Much appreciated thank you.

Dennis, I've not owned a 5000 but I've had a GPX4500 for many years. I have my favorite settings that hardly ever change and it seems to make very little difference when I change coil sizes. The same settings seem to suit all the coils I've had attached. I've rarely used the DD coil so I can't help you with that.

If ever you get confused with the settings just be sure you are switched to Mono and usually Enhanced. Hold the on/off switch down on startup until it beeps, select All Settings in the display. This will give you factory settings and it's a good place to start and suitable to find gold in most cases. Adjust the threshold to a very faint constant sound. Variations to this sound is what you are looking for. Phil

Hi Dennis.

PM also sent. Not sure if you had checked it.

Best of luck with it

Thanks mush appreciated

Thanks I will keep that in mind next time i get stuck.

Hi Dennis,

The best thing you can do is test, test & then test some more

Mono's, Dd's can react differently to different size targets/nuggets & a particular depth.

Bury a few different size targets @ around 30cm & use every coil u have, every imaginable settings u can dream up.

Be sure to setup the audio tone and response setting and volume setting to suit your hearing. Some people can't hear all high pitch audio signals or all low tone audio signals. Finding an tone which is more noticible to you will improve your overal detecting preformace as your setting the detector up for yourself and not someone else using their elses settings. Audio tone works well with response setting and set the volume to suit to your level of tolerance. I can't tell you what to set it too unless you lend me your ears.

If you bury a target and wave the coil over it its not an accurate depth test infact it should be seen as a signal test. The ground is different from place to place, metal targets are buried at different depths. Metal targets don't dig themselves deeper because your nearby. Depth is out of your control its always going to be variable. What you should be more concerned with is actually hearing the signal response from the target, setting up audio to suit your hearing levels.

Also can run a DD coil in mono setting. It turns the DD coil into a small elliptical type mono coil by using one side of the two overlapping wire coils inside a DD.
This used to work very well for me with an Extreme that I used to have. When using my DD coil in mono mode, I had the option to double check "iffy" targets by switching between DD and Mono mode on the control box.
Later models have improved noise reduction for mono operation so now it is possible to use larger mono coils. Still if you lack a small sized mono that is still an option on a 5000.
The 5000 also has an additional Fine Gold setting which works very well with most coils and particularly well with small coils and is my preferred setting whichever coil I am using.

I believe the more recent mono coils (Evo/Elite/Detech Ultra) were mostly designed around using the smooth timings but in particular Fine Gold on the 5000.
