Minelab’s winning combination
Minelab’s winning combination - detecting gold ‘easily at one meter’.
Combining a state-of-the-art Minelab GPZ 7000 detector with a GPZ 19 coil has proved more than profitable for a gold prospector in Western Australia.
The man, who wishes to remain anonymous, has used the combination to unearth a beautiful specimen containing 68-ounces (2.11 kgs) of gold worth some $110,000. It was the largest of a number of “considerable” nuggets found during the same trip.
The big one was discovered 800mm down on a piece of land which had been well worked over in the past.
“I’ve found gold at 1.1 meters and the testing I’ve done with the new GPZ 7000 and the Minelab 19” coil shows it can easily achieve that depth and more. I’m really confident that if there’s a big nugget down there you’ll find it,” the successful prospector said.
“It’s pretty simple really, the big ones aren’t always there, but you have to be ready in case they are. And if you’re looking for them, then you need the tools to find them.”
Since starting his gold-hunting career more than a decade ago, the prospector has always believed in having the best technology he could afford.
“I’d been having a lot of success with the Minelab GPX 5000 so I only hired the 7000 to start with. When I got it all set up I thought I’d start on an old patch and I couldn’t believe I’d left so much gold behind!
“So I bought a GPZ 7000 straight away along with the GPZ 19 coil and I found enough gold in the first 15 minutes to pay for the coil. I couldn’t believe I was still finding gold on this land.
“It’s like having a whole new piece of ground to go over, only you know there’s gold there.”
A man who takes his prospecting very seriously, he keeps careful records of his finds, the detectors used and the depth of the gold.
“The difference between the 14” and the 19” coil is huge. The GPZ 19 has more than double the depth of the 14 and will clearly find targets the 14 can’t detect,” he said.
But it’s not just the coil. With a range of new technologies, Minelab’s GPZ 7000 finds gold like nothing before it.
The GPZ 7000 provides much deeper ground penetration while maximising sensitivity for small nuggets near the surface.
“It is very sensitive to small gold - 0.2 and 0.3 of a gram - which was extremely surprising,” he said. “It’s practically unheard of.”
The GPZ 7000 also accurately balances and ‘tracks’ to even the most severe ground conditions. This latest find, in the northern W.A gold fields, was in tough clay that had to be soaked before it could be dug through.
“It’s difficult ground to work in the best of times but the new software in the 7000 handles the EMI (electro-magnetic interference) really well. I use headphones and it’s really quiet without all the pop, bang, wizz, you often get,” he said.
“You can bump the coil on the ground and not get the false signals like you’d get from other detectors.”
The GPZ 7000 provides a different user interface to earlier Minelab detectors and the software can be easily upgraded as new developments are made.
“I did the latest upgrade myself. It was easy to do and I was very happy with it. The detector was smoother and quieter than before.”
That’s important because the really deep finds can be quiet.
“They’re clear but they can be subtle. There’s no special range of settings which guarantee success, it all depends on the conditions, but I’ve found that walking slowly and listening carefully with a normal swing speed gets me the best results.
“Like they say, you can’t rush - you have to sneak up on nuggets.”
And, of course, it helps a lot if you’re sneaking up with a Minelab GPZ 7000 detector with a GPZ 19 coil.
