Digging in the Rain

Strangely, well for me anyway, I have heard many times from detectorists located in some parts of England that they hate the rain and most certainly won’t choose to go digging in it. Some even say it puts them off detecting altogether when they are ‘forced’ to dig in wet weather.

Unfortunately, if most of us in Scotland actively chose not to go out digging in the rain, then it is safe to say that we would have a mere handful digging days per year. Besides, our main machine is the incredible, fully water (and Scottish weather) proof CTX 3030 with the CTX 17 inch coil – without question the greatest all round, all weather machine ever produced.

Basic Metal Detecting Techniques - How to Get the Most from your Sites!

Swinging Techniques

Some machines have faster processors than others. Typically, the higher-end machines are able to process more ground, faster. Obviously, whipping your detector around at light speed won’t yield great results in an iron-infested site, but if you’ve got a vast area of open space with little to no targets, a faster swing speed will offer you the ability to cover more ground in search for hot spots (places with tons of signals indicating substantial human activity).

Better Understanding Zero Voltage Transmission (ZVT)

Following on from my last blog about the GPZ 19 coil, here some further tips to help you get the best from your GPZ 7000, irrespective of which coil you are using.  The GPZ 7000 is not difficult once you come to terms with the way the technology performs over the ground. It is a blend of behaviours which are dictated by ZVT technology, the Super-D coil design and the detector’s ability to tap into the full gamut of target information, thanks to being able to run a very low noise floor without any major trade-offs to audio stability.

Practical tips for using the new GPZ 19 Super-D coil

With today’s release in Australia of the much anticipated GPZ 19 coil, I thought this would be an excellent opportunity to provide some practical field advice to enable early users to get the best results from this ‘beast of a coil’. I’ve been testing and refining it with the Minelab engineering team for quite some time now, and have to say, it’s worth the wait (weight), in more ways than one!

One man's trash is another man’s treasure

Trashy sites… you either love them or hate them, but one thing is for sure, as a detectorist, they are hard to avoid. Whether it is a recreational park or an old homestead you come across, years and years of rubbish lie under the soil, the waste of previous generations; but the question is, are they worth digging? The answer is yes. Trashy sites require patience, being prepared to dig lots and lots of holes and they also give you the opportunity to really get to know your machine.

The GPZ 19 coil – does it really detect 30% deeper?

With the imminent release of the GPZ 19 accessory coil, I thought it was worth discussing its depth capability and how our 30% performance statement was derived. Typically these types of claims are commonly greeted with much concern and doubt, before many are even able to get their hands on the product and test it for themselves. Even then, there are a wide range of settings to choose from and soils to test in, so results can vary greatly depending upon the test conditions. Also, larger objects will typically be detected deeper for the same size coil. Anyway, some background information first…

Ferrous-Conductivity readings for Non-Ferrous targets

Recently we had a Facebook comment about the Target ID difference between our older Explorer SE detector and the CTX 3030:

“One thing I've noticed on the CTX is that an all copper penny sounds just like a silver dime and both will read 12 43. On the Explorer SE coppers would show as 7 21 and silver 03 23. But it's a small sacrifice to pay to straighten out the graph curve into the 12 line.”

So, I thought it was worth revisiting the rationale behind evolving the Explorer FE/CO discrimination method into the one used in E-TRAC and CTX 3030…

GPS Mapping with the Minelab CTX and GPZ Detectors (Part 2)

There are various ways in which you may use the GPS mapping options included with the Minelab CTX 3030 and GPZ 7000 detectors. This Treasure Talk entry is for those who do NOT want to have any data saved on their detector and who do NOT wish to use the XChange 2 software. It is, however, still possible to find very good practical applications in this limited mode. The key thing to remember is that all information displayed to you will be lost as soon as you power the detector off.

Discovery of the largest hoard of Roman lead slingshot in the world

Imagine finding the largest lead slingshot hoard in the Roman Empire…well we did, and once again in Scotland!  Roman sling shot are made of lead and weigh approximately 50g. They also have very distinctive shapes and are mostly shaped like lemons or acorns. This might not sound like a deadly weapon to our modern ears, but in fact, expert slingers could sling these so fast, the projectile had the same velocity and impact as a .44 Magnum- very deadly indeed.

The Metal Detecting Bible - Tools of the Trade

It’s no secret, detectorists aim to get things discovered and excavated. This month we’ll be looking at some of the different tools that detectorists use to locate and excavate targets. Each and every environment comes with its own set of challenges. It’s important to take a look at the environment that you’ll be hunting before you actually go out swinging. Unless of course, you have a ton of tools that you don’t mind hauling to every site regardless of the conditions. Sadly, I don’t think that’s the case for most of us. Keep in mind, while some of our main objectives are retrieving the target quickly and effortlessly, the main objective should be property preservation. The tools that we select to excavate our targets should leave the land looking as if we’d never been there when we’re done. So let’s start with a few basics that every detectorist should consider carrying to EVERY site.
