Whats Wrong With My GPX 5000

Recommended Posts

I bought this GPX 5000 second-hand and when I first had it it worked fine, but now when I turn it on it doesn't seem to be able to detect any signals. If I wand it over a large piece of metal it just about detects it and if I turned the unit on and off it seems to improve it. Could it be the coil?
I've made a video :

It's not a Chinese copy is it?

I have the original bill of sale from a metal detecting retailer with the corresponding serial number so I don't think it's a copy

There's a post june 10, 2014 by Reno Chris in minelab metal detectors titled .... if Your GPX Appears Broken, Try This.....where he explains how to do factory reset.

I've just done a factory reset and it's still not working. All I'm getting is the hum from the threshold and if I put it over a large metal object I get a signal but if I put over a coin on the floor it sees nothing.

I'm going to make a little short video to be put out on Saturday morning about my progress to fix it.

I was not able to get out today because we've had heavy rain and I'll probably do a live broadcast tomorrow night.

Hi Cleggy, welcome to the forum.

The first thing I would try is a factory reset then setup using basic settings.  The owner of this forum, Steve Herschbach, has instruction here:

Try a different coil...if the result is the same it is the control box...

I always had a spare power cord...they are a weak link, especially the way some use them.

If it is the coil you can repair it yourself if one of the wires is broke at the connector.

I've made this video to show you the faults I'm getting.

In the  video I talked about a live broadcast and that will be tomorrow night because this video will be going out tomorrow morning.

I see your coil wire is very loose, before you take it detecting you should tie the cord so it does not wobble. That will save many false signals.

yes, this has nothing to do with your current issue, just a tip for the future.

did you try a different coil yet.

there is some chance you have multiple problems, I bought a used 5000 that did...having another to compare would be helpful.

good luck

      GPX 4500. Been detecting for a while in the hills in California (Sierras) where I got started in 1970 ish with my White 5000 D I purchased from Jimmy Sierra at his shop in San Rafael. We’re still in touch although he says he doesn’t get out anymore but loves to read about others adventures. 
      then moved to New Mexico. I decided recently I needed to try my hand with Minelab and purchased the GPX 4500. I’m finding it difficult to find reading material on settings or proper videos. I have a friend that suggested a setting for the area I prospect in. I got a mono Commander and a GP Series coil with it. Hopefully I’ll find good info on this site. 😎
      Cheers

      I’ve been hunting a good site using the Deus and Equinox which has nails and small iron mixed in with good targets, some good targets being deep, but near or in the iron. My question is, will a GPX with Iron Discrimination turned up and the smallest DD coil pull out the deeper, non-ferrous items amongst heavy iron? Has anyone had any experience with this? I think for shallow targets the Equinox or Deus works better for shallow targets in this “machine gun iron”, but would like to see what others may have insight on for using the GPX. I’m assuming the fast setting and special soil timing may need to be adjusted as well. Thank you in advance.

      Can I reduce the sensitivity of my GPX 5000 but still keep good depth. 
      I'll show you the problems I'm getting in this video

      Need help. My equinox 600 doesn't change discrimination patterns when I switch detect modes. I am always in all metal mode. My boyfriend has the same machine and his changes with each mode...he doesn't know why mine does not. I can't figure it out...help please.

      I have had a Garrett ACE 250 for several years and just bought a very slightly used Garrett AT Pro a week ago.  A couple of times I did not get any sound when first turned on but after wiggling the coil cable it started giving tones again.  On occasion it has suddenly started chattering with almost no movement and I have done a reset and it corrected the problem.  My main issue right now is that if I bump the coil cable close to the connector I get a tone every time.  I have removed and re-inserted the connector twice making sure it is fully inserted but still get the tones.  I have made sure its not the connector itself.  I don't have another coil for the AT Pro to swap out.  I texted the previous owner to find out when he purchased it hoping it was less than the 24 month warranty that Garrett has.  Wondering how strict Garrett is on fixing issues like this or replacing a coil with a bad cable if I was not the original purchaser.  Any suggestions are appreciated.
