Why do coins sink?

November 15, 2010 02:08pm

Several months ago while conducting a routine field test of a Minelab detector, I got a signal from just underneath a fallen log – I moved the log and found a coin target which as it turned out was on the surface hidden from view by just a few leaves – the date was 1946. A few feet away another signal produced a 1986 coin from around the six inch level.

At the time I didn’t think much about it as it was a routine test and many targets were located that day and that’s what I wanted, as many targets as possible to assess the detector.

Chris Gholson - Introduction to Treasure Talk

November 12, 2010 05:15pm

Chris Gholson’s introduction to gold prospecting started as a young boy when his grandfather began taking him along on his many excursions into the Arizona desert to search for Indian artifacts, relics, and of course gold.

In 1998, Chris wrote his first book, Metal Detecting for Placer Gold. In 2002, he authored another book about gold mining with his colleagues from the University of Arizona and California State University. He is a columnist for Lost Treasure Magazine, and is contributing author for several other magazines including: The Gold Prospector, and the International California Mining Journal.

The power of positive thought

November 08, 2010 02:11pm

Do you know your mind is a far more important part of a successful electronic prospecting equation than even the technology in your detector? Well it’s true, and for a very good reason! Without positive thought there is very little reason to get out of bed in the morning, becoming confident in what your detector can do by learning what it has to offer is a very big part of the equation which then leads you to becoming more confident in succeeding.

A lesson I learned very early on in my career was to always look at the glass as being half full rather than half empty, so in the field I will always leave something in reserve as a positive motivator. A good example of this is...

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.
