What is a GPX?

cudamark said:
You're going to have to experiment. Not all gold bearing ground is going to have the same mineralization and not rocks. Coil choice is another variable that can have a significant impact depending on the site. Learn the machine and what the settings will do so you can make educated guesses, and then try a few.

I tested this from the ground and tried it with a ring and a necklace. The device responded to the ring at a distance of twenty-five centimeters, and the necklace weighing 15 grams was about five centimeters away. How is this possible? Does the geometric shape of the gold affect the power of the device?

The ring is solid, the necklace is tiny links, detectors sees individual links not a solid necklace.
 

GPX can = Dig HUGE holes that you are too lazy to fill and leave the rusty iron on the side of the hole. Many times there is a water bottle or snack wrapper laying next to the hole where someone took a rest after getting the the bottom.

Sorry that’s what I’ve seen since the Minelab PI’s have become popular with the rise of the gold price.

Tell me you don’t see this detecting on public land.

I’d like to have one.

Gaslight them!
Take a photo of a big honking gold ring/coin/pendent in the dirt that they piled up.

"Wow look at this, they dug it, and missed it"

Say the public spot, then put it on the local FB, Craigslist, Reddit.
But not on here. 😁
 

I tested this with a gold ring and necklace I had. With the gpx4500 device, the ring works up to 25 cm, but the 15 gram necklace only works up to 5 cm? Does the geometry of the metal affect the power of the device or are there special settings? I tested this with an 18 inch coil. Please advise. Thanks Ahmed

Hi. I imagine you are not using it for natural gold like nuggets.
Treasure Hunter above did answer you.
But anyway, you will find the more solid the gold object the deeper it will detect. On natural gold a 5 gram solid nugget will detect deeper than a specimen with 5 grams of very small bits in it. Just like you are seeing a more solid 1 piece ring detect deeper than a chain.
There are no settings that will change this.
There are things you can do to increase sensitivity though.
The use of a mono flat wind, or spiral wind coil such as Nuggetfinder Evolutions or Coilteks or Detech comparative wound coils rather than the bundle wound traditional mono coils. The sensitivity increase is quite noticable.
If ground permits and doesn't create false signals the use of Sensitive Extra will bump that sensitivity up even more.
If ground is noisy the flat winds can get noisy themselves and then a traditional wound mono or DD may be the coil of choice. You also wouldn't find sensitive extra useable under those conditions.
Anywho have fun out there.

Heck no. Don’t need any more yahoo’s up there.
 

been doing some Youtube research on deeper nugget detectors. GPX 5000 is 15 years old, GPZ 7000 is 10 years old, GPX 6000 is 5 years old yet if you want these machines to work properly you need to spend about 2 grand to get them modded.
what the heck is wrong with Minelab that after a customer spends close to 10 grand on a detector thats been around for years it still needs to be upgraded??? you would think every year of production they would try to improve upon each generation
a modded GPX 5000 seems to do a better job than a GPZ 7000
up here in Canada i saw a "brand new" never used GPZ 7000 for $10,000 about a $4000 savings compared to brand new from a store
this guy does comparisons
for those of you that know
is a modded GPX 5000 really better than a GPZ 7000?
 

I’m pretty sure I heard that there are counterfeit Minelab detectors out there. Beware on the really good deals unless you know someone.
 

yes, the detector mod guy on youtube had 3? gpx 5000 detectors on his bench and all 3 cases and stickers and colors were different. I cant remember if they all were genuine or not. another guy was saying to stay away from amazon and ebay. Thankfully on Amazon.ca the scammers are asking $25,000 for a GPZ 7000 or $5000 for a Gold Monster 1000 lmao.
