David Cuisinier - Introduction to Treasure Talk

February 04, 2011 09:23am

Here’s David Cuisinier, the latest member of the Minelab’s Treasure Talk blog team. David has a great deal of experience with Minelab metal detectors, especially on the beach and underwater. He’s an active metal detector user, and has travelled all over France to prospect as a hobby in various conditions: on the ground, in caves and tunnels, in rivers and at the beach.

en Fançais - Voici David Cuisinier, le dernier même à rejoindre l’équipe de TREASURE TALK. David a une long expérience de la détection de métaux notamment avec les détecteurs Minelab de plage et sous marins. Ce passionné pratique ce loisir toutes les semaines, et voyage aux quatre coins de la France pour exercer sa passion dans ses nombreuses déclinaisons : détection à la plage et en terres intérieure, mais aussi sous l’eau, en rivière et dans des tunnels.

Detecting, a passion or an obsession...

February 03, 2011 05:00pm

To be unexpectedly asked by Minelab to be a contributor to their Blog section, was both a surprise and also a real honour. So firstly I would like to say hello to all Blog readers from Hertfordshire in the UK. Being a rather diverse metal detectorist I love everything metallic from finding Celtic coins to tracking down the crash sites and excavating the wreckage of World War Two aeroplanes, so it might appear easy to write something...but crikey where does one start? What would like minded individuals wish to read and expect? Well I have such a large spread of topics that could be of interest, I need some time to consider what order to position them so this first blog is simply a “Hello” with a sprinkling of hints regarding “things to come”.

The Power of SALT-GOLD

February 01, 2011 04:46pm

Since the release of the GPX 5000, one of the lesser talked about new features is the Salt-Gold timing. This replaces the Salt-Coarse timing found on the GPX 4800 and previous GPX and GP series models, so what is different about it?

Introducing Julian Evan-Hart

January 28, 2011 11:54am

Julian is from Hertfordshire, England and from a young age has always been interested in fossils and antiquities. When aged six he found a mammoth tooth lying by some recent road works and that was it! His passion took off!

Later Julian’s interests turned to aviation archaeology and wildlife. He has been involved in some 200 aircraft excavations and crash site searches. It was in the late 1970s that the logical move to metal detecting took place. Julian says “I simply love the honour of being able to handle antiquities and coins from bygone ages”.

Hot rocks - Part 2

January 21, 2011 04:30pm

While hot rocks can be incredibly annoying, they are actually a good indicator that gold may be nearby. As most experienced prospectors know, the yellow metal likes to hang out in highly mineralized ground. In fact, the worse the soil is and the more hot rocks there are, the better the odds of walking over a nugget.

Learning to deal with hot rocks does take patience, but with a little practice you’ll have a handle on them in no time. Here are a few tips that I have found useful for dealing with them:

The halo effect when nugget hunting

January 19, 2011 04:29pm

There have been a number of forum posts, questions and comments concerning the ‘halo effect’ that many encounter while detecting. Most explanations are great but sometimes too complicated.

Let’s look at what the halo is and how it affects you while detecting. In the simplest form the halo is nothing more than the oxidisation of a target. Anything buried in the ground that will rot, corrode, tarnish or leach can cause a halo effect.

The halo can be very frustrating to detectorists due to the fact that what seems to be a good target can simply disappear.

Achieving good Ground Balance when using the 'Smooth Class of Timings'

January 14, 2011 03:35pm

For my fourth blog on Treasure Talk I want to pass on some of my experiences about achieving a good Ground Balance (GB) when using Smooth, Enhance or Fine Gold. As most of you will know by now the 'Smooth Class of timings' were developed for the GPX Series to allow the use of a Monoloop coil in highly mineralised soils. The timings do this by removing a lot of the ground signal, however in doing so they also remove a small amount of the target signal too, dependent on Ground Balance position, target orientation and more particularly size and shape of target.

The reason it’s suggested a Monoloop coil is better for performance is they provide better...

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.
