Getting the best out of the Eureka Gold

October 29, 2010 05:00pm

The Eureka Gold is Minelab’s flagship VLF gold detector, which has been overshadowed somewhat by the GPX series, but it has quietly gone about its business for years now, and has built up an excellent reputation. It is a popular model for a number of reasons: lightweight, economical, hip-mount capability, high sensitivity, good iron reject, long life NiMH pack included, fast Auto ground balance, 3 switchable frequencies, but most of all, it just works!
For users that already have a Eureka Gold, or those in the process of buying one, here are a few tips to help you get the best out of this little gold machine:

Corfe rally report

October 26, 2010 02:58pm

Hi every one, this is my first blog and I’ve decided to report on this years annual Minelab Owners (MLO) rally. This year we returned to Corfe Dorset England where all our fields seem to overlook the very historic Corfe Castle.

Corfe castle sits on a prominent hill at a natural pass through the Purbeck hills. This pass has always had strategic importance, and castles have been built here to guard it since Saxon times (if not earlier). The ruins you see today are the result of the 17th Century civil war, when it systematically destroyed in 1646 by the parliamentary Roundheads.

'Recovery Deep' in depth

October 22, 2010 02:23pm

The Recovery Deep setting on the E-TRAC, Explorer and Explorer SE detectors is designed to enhance the detection and identification of deep targets. This article will explain the way in which deep recovery mode enhances the operation of the detector and points out those situations when you may not choose to use this setting.

When Recovery Deep is turned on, it only has an effect on weak signals, stronger signals remain completely unaffected. When Recovery Deep is turned on and a weak signal is detected, the identification signals undergo stronger filtering to smooth out the data

Gordon Heritage - Introduction to Treasure Talk

October 19, 2010 04:33pm

I’d like to introduce Gordon Heritage as a new member to Minelab’s Treasure Talk blog. Gordon is a well known English metal detectorist with over 34 years of detecting experience.
 
He first started coin hunting on parks and commons in Buckinghamshire and soon amassed many thousands of coins dating back to the 17th century. Not content with this he started researching areas that had yielded older finds and in 1987 found his first hoard of 627 Roman silver denarii. This find transformed his hobby into a fulltime pursuit and it wasn’t long before his exceptional discoveries were being featured in treasure hunting magazines.

Noise the enemy of detectorists

October 15, 2010 04:20pm

The first thing new comers to detecting will learn is, detectors are all about noise; they can seem like a talkative child who rambles on incessantly with the poor listener not being able to make head or tail of what it is they are trying to say. Noise or the lack of it is one of the main reasons why Minelab have what is considered to be the “World’s Best Metal Detection Technologies”. In my first blog as a guest writer for Treasure Talk I want to talk about noise and why I feel the lack of it makes the GPX 5000 so unique.

Specific Ground Balance on the GPX detectors

October 13, 2010 01:58pm

The GPX-4000 metal detector first introduced a special ground balance mode called Specific Ground Balance which is still used in newer GPX detectors. This ground balance mode may allow the detector to ground balance in areas that otherwise would have too much ground noise. The Specific mode uses a special second-order ground balance algorithm that can deal with more complicated ground responses than the normal first order ground model.

If you ground balance in the normal way and the detector still displays ground noise then this may be a situation for Specific ground balance mode.

So, you've found a few nuggets, now what?

October 08, 2010 01:09pm

So, you’ve bought yourself a brand new gold detector, lots of gold maps, have gone out a few times and have finally found a few nuggets, and the 6 million dollar question is….. “Now what?”

You obviously want to find more, so what is the best way to go about it? Well it is generally true that where there is one nugget, there should be more nearby, so carefully detecting the surrounding area should be your first priority. Detect under every bush, around every tree, move fallen logs and detect the ground under them. Now let’s assume you’ve done all this for one extra little nugget, and you feel like you should move on to another area. Okay, rule no.1, don’t think the pastures are greener on the other side of the hill.

Notch Discrimination on the X-TERRA - Ever wonder what you're missing? Part 2

October 06, 2010 11:34am

Part One of this blog post described how the X-TERRA categorizes targets, based on their conductive values. In Part Two, learn how to increase your opportunity to detect jewelry and old coins by modifying the preset Patterns.

Now that I've outlined how the ferrous vs. conductive properties are represented by the visual and audio TID, let’s evaluate some targets. If you turn your X-TERRA 70 or 705 to the Coin/Treasure Mode, and set it to hunt in factory preset Pattern 2, you will be rejecting notch segments -8, -6, -4, -2, +2, +4, +6, +14, +16, +18, +20, +22, +24, +26 and +48. You will be accepting notch segments 8, 10, 12, 28, 30, 32, 34, 36, 38, 40, 42, 44 and 46. Those of you who have performed target ID tests with your X-TERRA know that this setting will accept U.S. pennies, nickels, dimes, quarters, half dollars and dollar coins. A Coin hunters dream?

Jonathan Porter - Introduction to Treasure Talk

October 01, 2010 03:31pm

I’d like to introduce Jonathan Porter as a new member to Minelab’s Treasure Talk blog. Jonathan Porter is a well known Australian professional prospector with over twenty three years of gold detecting experience. He first started prospecting as a hobby with a Minelab GT 16000 metal detector back in 1987 on the Palmer River gold field in far North Queensland.

His biggest gold nugget to date weighed in at 83 ounces along with 79 and 54 ounce pieces unearthed the same day using a Minelab GP 3500.

In 1995 Jonathan was asked to assist Minelab with the evaluation and field testing of Minelab’s MPS metal detectors, including some countermine work. He also continues to work in close association with Bruce Candy, Minelab’s Chief Scientist.
