E-TRAC - Manual versus Auto features for expert users

January 10, 2011 11:40am

The E-TRAC has some very useful ‘Automatic’ features that allow users to find targets at great depths from day one.
Auto Sensitivity and Auto Noise Cancel work together to stabilise the E-TRAC’s performance, limiting noise from iron, changes in mineralisation and electromagnetic interference (EMI).
Although both of these auto features work perfectly well, experienced users wanting to squeeze extra performance from their E-TRAC soon switch to Manual Sensitivity, and in doing so increase their find rate.
In this blog I’m going to argue the virtues of also manually setting the noise cancel feature.

X-TERRA - Which frequency coil should you use?

January 07, 2011 01:15pm

Well, it all depends on what you are looking for? There are three frequencies available: (1) Low, (2) Medium & (3) High.

The Low Frequency of 3kHz would be well suited to searching out metals of a high conductivity such as copper and silver coins. It might be considered a good cache hunting coil. Useful also in hunted out parks for deeper silver coins which are masked by trash items.

The Medium Frequency of 7.5kHz is...

X-TERRA... Controlling the search coil

January 04, 2011 10:10am

When it comes to sweep speed, the X-TERRA is a very forgiving detector. You can operate with a relatively quick sweep in wide open areas, and slow down when targets are abundant. But to gain a better understanding of how sweep technique may affect the quantity of our finds, let's first analyze the field of detection for both the X-TERRA Concentric coils and the Double-D coils.

Based on my field analysis, with the center of the coil as the "hot spot", I find the field of detection for a Concentric coil will go "straight down" until you reach approximately 55 - 60% of the maximum depth for a specific target. In other words, if you are capable of detecting a target at maximum of 10 inches, you will find the circular field of detection begins to narrow at the 5.5 to 6 inch depth level.

Safari - The quiet achiever

December 21, 2010 12:17pm

Full Band Spectrum or FBS, is Minelab’s patented 28 Frequency Technology, used in high-end coin detectors such as the Explorer series, and now the E-TRAC. For detector operators who are familiar with older analogue detectors such as the Musketeer Advantage, the number of fine tuning options available on the Explorer SE Pro and E-TRAC and the ability to create customised search patterns could seem a little daunting at first, so making the move up to FBS may seem like a big jump. This is where the Safari comes in, and provides a stepping stone between older single frequency units, and the high end Explorer SE Pro and E-TRAC.

Why I like to use Large Mono Coils

December 14, 2010 02:52pm

I recently went out for a few hours detecting not far from my home here in Clermont (Central QLD, Australia). The reason? I had just received a new coil, an 18” Commander Monoloop, and I wanted to give it a go on some deepish ground I knew. Because I had also just bought a new POV (Point of View) camera I decided to rig it up on the detectors stem and record some of the potential action for posterity.

What prompted this blog were my experiences during filming using the large Mono and my thoughts on their effectiveness in the arsenal of serious prospectors...

I found a Civil War relic; what's it worth?

December 10, 2010 03:37pm

To be honest, any collectible item is only worth what another person or entity will pay. Price guides are very useful, especially for the beginning collector, but current market value, current "hot" item craze, buyer or sellers market and the economy (let's not forget sometimes local, State or Federal laws concerning the sale of antiquities) will define what a certain relic will bring.

A good starting point for American Civil War relics would be the North/South Traders Civil War price guide. These are updated about every 2-3 years and offer the collector a very broad range of Civil War collectibles including non dug items such as photo's, paper money, flags and more. Another good reference would be...

David Keith - Introduction to Treasure Talk

December 09, 2010 10:00am

David Keith began metal detecting in the early 1980s after joining a Civil War re-enactment Regiment. His fascination with history has always been of keen interest to him especially prehistory and the American civil war.

His desire skyrocketed when he dug his first civil war bullet in a friends yard in Tennessee. He became an authorized metal detector dealer in 1985 and became one of Minelab's early dealer's in 1992.

His initial experience with the original Sovereign yielded him 10 civil war belt buckles from a hospital site that...

Hunting by ear... Audio tones on the X-TERRA

December 06, 2010 10:08am

With "old" being a relative term, I hunt for old coins at old sites. The part of the world that I live in wasn't settled until the mid 1850's. So finding coins older than 1900 is considered to be a good hunt. Many of my favorite spots to detect are old homesteads and farm sites. With the houses and out buildings long gone, to the passerby, most of these places look like any other corn field in this part of the Country. Pieces of brick, stone, glass and pottery are some of the things that I look for when wandering across these corn fields. And when I start hearing the low tones produced by nails and other "farm trash", I know I'm getting close to where I want to be...

How I got into electronic gold prospecting

December 01, 2010 09:35am

Around 1983 I was introduced to “Gold Prospecting” by a neighbour who moved in beside us. I remember spending many weekends dry-blowing gullies and being pleased with the few grams of gold got. I bought a VLF machine and spent time learning how to fly it before I was rewarded with a “massive” first nugget weighing 0.1 grams.

The nuggets rose in weight as I learned more about this strange machine until I got to a stage that I thought I was proficient in its use. In those early days...

Peter Cragg - Introduction to Treasure Talk

November 26, 2010 09:12am

Peter or as he is known on detecting forums as ‘Qld Sandy’ was first introduced to gold prospecting by a new neighbour in 1983. In that year he purchased his first VLF metal detector. His first gold find was a 0.1 gram piece and the sizes grew as his experience did. In those early years he spent as much time as possible detecting for nuggets and sometimes coins for a different challenge. He has through the years graduated to nearly every new Minelab SD, GP and GPX metal detector.

Because of Peter’s interest in detecting and his desires to assist others learn and become proficient in this hobby he recently opened ‘Gold City Detecting’ in April 2010...
