E-TRAC - Threshold and sweep speed

April 27, 2011 02:43pm

On the Minelab Owners forum we often see questions concerning Minelab’s flagship FBS metal detector, the E-TRAC.

A couple of regular questions are: Do I need a threshold? How fast should I swing my coil?

The answer to these questions is related, and in this blog I’ll explain why.

Detecting, a passionate obsession!

April 15, 2011 04:38pm

Thinking about my first blog is detecting a passion or an obsession; well for me I must admit it’s more likely to be an obsession. Funny thing is since the vast majority of my friends and colleagues are detectorists I rarely encounter the “What in all weathers traipsing across fields?” type of question.

Well for me and I suppose the vast majority of like-minded detectorists it’s a mixture of what’s that next signal going to be... the anticipation, the feeling and knowing in some cases that you are on a superb site and the potential to make good finds is good.

E-TRAC - Two Tone Ferrous… unlocking the "mystery" Part 2

April 08, 2011 03:36pm

In part one I explained what ‘Two Tone Ferrous’ (TTF) is and how it works. In part 2 I’ll explain why I use it…

For me, deciding whether to use ferrous tones or conductive tones depends on the amount and type of "trash" at each site. As a coin-shooter who hunts old farm sites, I believe there are instances where TTF is the optimum choice.

If I am hunting an old farm site with an abundance of iron trash, I run a fairly “open screen” using TTF (little or no discrimination). A low tone is provided for all targets with ferrous readings of 18 or higher...

Heritage Interviews

March 31, 2011 02:06pm

I’m proud to introduce a new series of interviews, which will be hosted on MLOtv. These interviews are brought to you in collaboration with Minelab metal detectors.

The concept is simple; we travel to finders of important discoveries and interview them for MLOtv. The first of these interviews will be of British finders, but it’s our intention to expand this series worldwide.

Gain, what’s a good level to start from?

March 18, 2011 12:12pm

On page 63 in the GPX 5000 Instruction Manual, Gain is described as being:

“…..a function that allows the GPX Series to be optimised for differing conditions; controlling the sensitivity of the detector to its environment and targets.”

Basically speaking this means you can use the Gain control to lift or brighten the response from a signal, a little like increasing the volume of your detector but in a more dynamic way.

Finding Civil War military camps: Getting permission

March 16, 2011 03:28pm

Finding Civil War military camps from ages past requires a number of things. Among those are firstly, research, which includes books, diaries, maps and time. Secondly, you'll need permission to access land where you feel a camp or camps may be located. Third, equipment! A good metal detector that can handle multiple soil conditions, navigate ferrous trash with good discrimination, and go deep. We can break these three categories into separate discussions, so I'll start with getting permission, something that is paramount to legal metal detecting.

Pitch Hold in E-TRAC & Explorer SE Pro

March 11, 2011 02:41pm

The Pitch Hold mode in the Response menu can be a very interesting choice of audio sound to use. While not for the faint-hearted due to its undulating audio, if a person is willing to give it time, the effort in learning its audio nuances will be well worthwhile. Essentially, it works because the pitch of the target signal will hold the Threshold hum sound until the next target is detected. i.e. the threshold mimics or adopts the tone relative to the conductivity of the target.

E-TRAC - Two Tone Ferrous... Unlocking the "mystery" - Part 1

February 25, 2011 04:31pm

While browsing several metal detecting forums, I've noticed numerous posts regarding the use of Two-Tone Ferrous (TTF) and how it has seemingly "increased the results" for many E-TRAC metal detector users. I won't disagree that they may be finding more than before. However, I believe the reason for their new found success is due to more than simply their choice of audio tones.

Finding the crystal gold patch

February 18, 2011 04:38pm

I thought that maybe you all might be interested in how my prospecting mate and I hit upon the “Crystal Gold” patch. We had been detecting an area that we found a few decent nuggets in, including a very nice pendant quality nugget that we christened the “dog t#rd” because of its long and thin shape, and my mate (he found it) wouldn’t let me near it for a long while because I kept saying it would disappear into my collection. This particular day we were detecting the same area and the only nugget was a 15 grammer that I scored from the gully that ran through this spot below where “doggy” was found. I suggested that we should go and look at a spot that I found plotted on a map, as it gathered my interest because I’d never seen it listed on any other map I’d ever looked at for this area...

Détection dans une mare (première partie)

February 15, 2011 05:06pm

La détection de métaux ne se résume pas aux champs et à la forêt. Ainsi nous allons vous présenter des manières différentes de prospecter, que ce soit dans une rivière, une grotte, un souterrain, un puits, dans des murs ou dans d’autres lieux auxquels vous n’oseriez penser. Aujourd’hui, nous allons traiter de la détection dans une mare et vous raconter l’une de nos sorties avec un professionnel de la recherche aquatique : Mudy Diver.
