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.

Grand Opening of the Minelab Technology Training Center

September 27, 2010 04:08pm

“Fantastic”, “unbelievable”, “This is great, a company that cares about training” were just some of the many positive remarks made during the Grand Opening of the Minelab Technology Training Center in Prescott Valley area of Arizona.

Friday was another ground breaking day in the metal detecting industry. After being involved in this sport for over 40+ years this is the first facility that I can think of that is dedicated to training and I want to thank everyone that made it a great day in the mountains of Arizona.

Notch Discrimination on the X-TERRA - Ever wonder what you're missing? Part 1

September 24, 2010 03:31pm

A guide for US coin-shooters
A metal detector does exactly what the name implies. It detects metals. Set to accept everything, you will find nails, foil, pull tabs, jewelry, coins, tokens, relics etc. Anything that is metal. In order to avoid digging those targets you don't want to dig, we implement a feature known as discrimination. Metal detector discrimination is basically the same for all makes and models. Some may do it better than others, but the theory is universal. Simply put, discrimination is the ability to adjust your detector so that it accepts most of the targets you want to dig. And, rejects most of those targets you don't want to dig.

Randy Horton (Digger) Introduction to Treasure Talk

September 21, 2010 03:18pm

I’d like to introduce Randy Horton as a new member to Minelab’s Treasure Talk blog. Randy (or Digger as he’s known in many circles) has been metal detecting in the Central US for over 38 years and has a passion for finding old coins at old sites. In addition to performing field tests for several manufacturers (including the Minelab X-TERRA), he also serves as Moderator on the X-TERRA forum at Find's Treasure Forums ( Digger has written several articles, and enjoys sharing his thoughts and tips on various aspects of the hobby. His detectors of choice include the X-TERRA, E-TRAC and Musketeer Advantage. If you like to hunt for old coins at old sites, make sure you introduce yourself to Digger.

Don't forget Factory Preset!

September 20, 2010 01:50pm

I have heard from some users that have tied themselves into knots when trying to find the best settings for their detector. This can happen because there are some combinations of settings that don’t work well together and there are some lesser used settings that you may have set and then forgotten to check.

In these cases please remember to perform a Factory Preset. This will return your detector to the settings that it contained from the factory.

X-TERRA Coil Range

September 13, 2010 11:02am

Why are there so many coils available for the X-TERRA series of detectors?
Good question.

Currently, there are eight coils available to suit your X-TERRA detectors.
All of them do mostly the same, detect metal but a few of them are ‘specialist’ coils more suited to a few tasks “the Pros” or seasoned hunters indulge in!

While there is absolutely nothing wrong with the “stock 9 concentric” that comes as standard kit with a lot of X-TERRA’s, the option to customize your detector without shelling out buckets of money is offered through what’s termed as VFLEX technology available only on the X-TERRA range.
