Gpx 5000 Coil Recommendation

Recommended Posts

as I already put in another post, I just bought a second-hand gpx 5000.  It comes with the comander 11 DD and 11Mono coils.  I would like if it is possible for a colleague to recommend a coil to complement the ones it brings.  Its use would be to search for coins.  I've been looking at the detech 15 inch DD ultra sensing.  If anyone has used it, what can you tell me about it?

Hi, I use a 12.5" DD coil from Detech for coin hunting on beaches. I have not tried it in fields as much, but when I did, it worked fine. The 15" ultra sensing sounds interesting. If you buy one I would be interested in knowing how you like it.

Saludos Luis!

I own the Detech 15DD Ultra Sensing coil for use on my GPX 5000.  I can say it runs extremely smoothly in both normal and sensitive extra timings in medium to high mineralization areas I've used it.  It was much smoother in difficult ground spots than when using my mono coils.  

This coil is also quite sensitive to small items, both ferrous and non ferrous.  I found many small bits of iron wire and small shards of nails going over old areas, along with a few small lead pieces of bird shot.   I managed to find a couple of 1g+ nuggets with mine at a depth of around 8 inches in a spot with high mineralization where mono coils are not able to run in normal or sensitive extra timings.  These nugget signals were clear and repeatable, though starting to get faint.

I ran my machine with the "iron rejection" setting on a a level of 5 of 10.  When I encountered larger or shallower trash items, the detector blanked out the signal and the few I dug were in fact iron like nails or flat iron.  I found at a setting of 5, small ferrous items would not blank out until within a few inches of the coil.  I did not try higher rejection levels since I tend to dig most targets in this spot, as it has had a lot of nuggets for me.

The coil also pinpointed well for me, even on smaller items as long as they weren't deeper than 3-4 inches.  The main disadvantage of this coil is the weight.  It weighs 1350g and after 2-3 hours of swinging, I rigged up my bungee cord for the rest of my detecting time.  15 inches also makes it necessary to dig wide holes, so that is something to consider in areas with rough terrain or a lot of rocks.  

I've seen a few reports and viewed several videos where relic hunters use this coil successfully.  For general coin hunting, I don't think this coil would be ideal since the discrimination on the GPX 5000 isn't likely to be useful in areas with extreme amounts of modern trash like aluminum or areas with dense iron objects.

Thank you very much for the answers.  At the moment it seems that I am going to stay with the 11th DD comander.  When I have more experience I'll see what I do

The 11" DD Commander is pretty good for coin hunting, of course I'm comparing it to using a VLF but the depth it can get is pretty amazing.

I have the 15x12" DD Commander also, that's a good coil also but I prefer the 11" as it's lighter and the bigger size starts to feel hard work and I didn't really notice a depth difference on coin size targets.

Spend some time on the 11" and see if you think you need anything else, you might find you're satisfied.  It also runs nice and handles EMI pretty well considering.  The ultra sensing Detech might be a bit worse with EMI being a spiral coil and will more sensitive to small targets so tiny bits of junk might be more of a problem.

The Detech Ultra sensing coil comes in mono and DD, they're a decent price too.  I might give one of their DD coils a go one of these days, I'm not interested in buying any mono GPX coils, I've got a great selection of Mono's, it's DD's I'm lacking and I'm starting to get pretty interested in using my GPX as a coin unit with the deep coins around here as it doesn't get used for gold much if at all anymore.

      I have been detecting an old home site. I started out with my ORX and the x35 9" coil it found alot of targets, and then kinda went quite, so i grabbed the Tarsacci, with its 12" coal and the ground let up again , and in the one spot the east yard it to went silent, but what gagged me was i was digging down 14 inchesand doing what i call a frontabout 3ft wide and just detecting the dirt i was throwing out of the hole and using a magnet to pull out the iron and going over the dirt again but now i was using the Mackro racer with the 5" coil to do this and it was pulling out lots of non iron targets this way but what caught me off gard was when i went out side of the hole and just for the heck of it started scanning the surface the other two detectors had gone over , i started getting hits, pulling up more shotgun shells and other non iron targets , so the 5" Racer coil was doing somthing the other two could not do . it was getting in between the metal and at a good 6 "  , this took me back because i figured  no way it would do so well but it did and is ,

      Early wet Weather in Northern Nevada, sure messed up a few of my hunts!  But, this last Hunt was called Rain or Shine!  Be there or miss out with the original hunting party.  We had half the amount of coils on the ground during this hunt and managed to find a few sweet spots of dinks to add to our pokes.  Rain on us with snow in the ground 200’ above us all 4-Days!  6000, Retune Button got a workout.  I kept the 11” Mono on.  Tried the DD for a few hours with no luck, don’t know if the ground and line I took was bad, but the guys behind me where finding nuggets…so back to the 11”.  My truck is out in the drive way in the wet Weather still loaded up with me gear!  Getting wet again to unload it, I can’t wait 🤨
      Until the next Hunt!

      I’m looking for an after market COIL SUPPORT for a COILTEK 10X5 EQUINOX coil…. I just finally bit the bullet and found one…. I’d like to put a coil support on this coil to hopefully not break the tabs too soon on it…. Does anyone know where a coil support for this coil can be obtained ? ? ?………thanks …..Al

      Is there or has there been any comparison testing done in the field on depth with the 6000 vs the 7000 using the NF 12" Z-search coil.
      Thanks . . .

      I had something strange happen, today. I had my GPX 6000 battery fully charged and fresh off the charger.  It had completed its charge cycle and then trickle charged overnight.  I popped it in the detector and started detecting. Within five minutes the battery meter dropped from three bars to two bars.  If I turned off the detector and let it sit for a 5-10 minutes and then turned it back on, it would go back up to three bars for a short period of time before then going back to two bars. Has anyone else noticed this with theirs?

      Hey all, still have a gpx 4000 I bought from AK M&D. Guess it's time for an upgrade. My Question is does the 4500 have enough improvements to justify the upgrade
